Dude. I was skeptical ordering a crate engine from Poland but WOW. Dropped this 350 into my 1989 Sea Ray Sundancer and it fired up on the first crank. Compression is dead even across all cylinders. Dariusz even emailed me the break-in procedure personally at 11pm his time. The packaging was insane — engine arrived on a custom pallet with zero damage. Already put 40 hours on it and she purrs like a kitten. Will 100% be back for the transmission next spring.

Rather impressed, I must say. The outboard was exactly as described — low hours, immaculate condition, and all paperwork in order. Communication was prompt and professional throughout. My only minor gripe was that DHL took an extra day due to customs, but Marine Engine Service kept me informed at every step. Fitted it to my Orkney Longliner and she's running beautifully. Fair price, honest people. Would recommend to any serious boater.

Sehr gut. I am a marine engineer with 22 years experience and I inspected the rebuild work myself when I visited the workshop in Zaton. The cylinder honing was within 0.0005" specification, and the crankshaft was magnafluxed properly — I checked the report. The engine dyno sheet showed 485 hp at 2800 rpm, exactly as promised. German precision meets Polish craftsmanship. Mein Charterboot runs now better than new. Die Rechnung war korrekt und die USt-ID funktionierte einwandfrei.

Magnifique! My Beneteau Antares is my life — I live aboard 6 months a year. When the D6 started smoking at idle, I was devastated. Dariusz diagnosed it via video call (at no charge!) and suspected the injectors. He was right. The service kit arrived in 3 days to Marseille, and with his step-by-step video guide I completed the job myself. The smoke is gone, fuel consumption dropped by 12%, and the Mediterranean has never looked more beautiful through clean exhaust. Merci beaucoup, mon ami.

MAMMA MIA! This engine is a BEAST! I put it in my restored Riva Aquarama and now she does 52 knots flat out. The sound — bellissimo! Deep, angry, like a Ferrari of the sea. Dariusz helped me choose the right camshaft for my application and even recommended the perfect propeller pitch. Shipping to Genoa was fast, only 5 days. The crate was so well packed my dock workers couldn't believe it came from Poland. Bravissimo, veramente professionale. La prossima estate comprerò un altro per il mio gommone!

Perfecto. I was worried about shipping to Canary Islands because many shops refuse, but Marine Engine Service arranged everything including the special maritime freight to Santa Cruz. Engine arrived in perfect condition, no scratches, no rust. Installed in my fishing boat and the power is incredible — 475hp feels like a rocket compared to my old 320hp. The price was much better than anything I found in Spain. Muchas gracias, totally recommended for any Canarian captain.

As a boat yard owner in Rotterdam, I have dealt with many engine suppliers. Marine Engine Service is now my preferred partner for transmissions and rebuilds. We ordered two ZF63IV gearboxes and their team flew in to supervise the installation on a 45ft motor yacht. The alignment was done with dial indicators — proper procedure, not guesswork. The VAT invoice was correct and their English is excellent. Professional, punctual, and they know their stuff. We have since placed three more orders. Aanbevolen voor alle Nederlandse jachtwerven.

I buy the brake kit for my boat trailer and it is very good quality. The price is nice, cheaper than local shop in Bruges. The shipping was 4 days to Belgium. I give 4 stars not 5 because the instruction manual was only in English, not in French or Dutch. But Dariusz send me a translated version by email after I ask, so it is okay. The brakes work perfect now, very strong stopping. I will buy again for sure. Merci!

Clean work. I booked the Complete Care maintenance plan for my Nimbus 365 before the Baltic winter. The team arrived on time, worked efficiently, and left zero mess in my engine room. They fogged the cylinders properly (many mechanics skip this), stabilized the fuel, and even sent me photos of the zinc anodes they replaced. The digital service log they provided is excellent — I appreciate the transparency. Boat started first try in April. Tack så mycket.

Living in Norway, I need an engine that can handle the fjords and the rough North Sea weather. My Yanmar 6LY3 was burning oil badly — 1 liter every 10 hours. Marine Engine Service did a complete top-end rebuild including new valve guides, piston rings, and a re-honed block. Now it burns ZERO oil after 80 hours of hard fishing. The price was about 40% less than what the local Yanmar dealer quoted me, and the warranty is the same 24 months. Solid work. Tusen takk!

Brilliant service! I needed a new engine before the sailing season started in May, and Dariusz guaranteed delivery within 10 days — it arrived in 8. The Mercury 5.7L was a perfect drop-in replacement for my old Crusader. All the mounts lined up, the wiring harness was compatible, and even the exhaust manifolds bolted right on. Saved me weeks of fabrication. My family and I have already done two weekend trips to Bornholm. Kan varmt anbefales!

Good product, fast shipping. The engine mounts and suspension kit for my Targa 27 fitted perfectly. Finnish winter is hard on rubber mounts — they crack every 3 years. These ones look much higher quality than the OEM parts I replaced. Price was fair, communication was short and direct (I like that). Kiitos.

Jako polski klient mogę tylko polecić! Przyjechałem z Gdańska do Zatonu z moim silnikiem Mercury Racing 525 EFI. Dariusz osobiście nadzorował pracę na hamowni. Wynik? 542 KM i 678 Nm — więcej niż deklarowane z fabryki! Mapa paliwowa została dopracowana pod moje śruby i styl pływania. Warsztat czysty, profesjonalny sprzęt, a ceny naprawdę uczciwe. Faktura VAT od razu, bez problemów. Polecam każdemu kto szuka mocy na Bałtyku!

I run a charter company in Split with 6 boats. We ordered 3 Yamaha F150 outboards from Marine Engine Service for our new fleet expansion. Not only did they beat the local Croatian dealer price by €800 per unit, but they also delivered all three at once with synchronized serial numbers — important for our maintenance records. Dariusz arranged the transport to Split port and handled all the CE documentation. The engines have now done 200+ hours each this season without a single issue. Hvala puno, you have a customer for life.

Getting a 500kg engine to a Greek island is never easy, but these guys made it happen. The Cummins QSC arrived by truck to Piraeus, then ferry to Paros where my boat was waiting. Dariusz coordinated with the ferry company and even called me when the engine was loaded. The engine itself is magnificent — 600hp of pure reliability. Installed it in my commercial fishing vessel and my fuel economy actually IMPROVED by 8% compared to the old CAT. Ευχαριστώ πολύ, Marine Engine Service!

Merhaba! I was nervous about customs between Poland and Turkey, but Marine Engine Service prepared all the documents perfectly — ATR certificate, commercial invoice, packing list, everything. The transmission overhaul kit for my Borg Warner Velvet Drive arrived in 6 days with zero customs issues. The parts were genuine and the rebuild guide video they sent me (in English, but clear) was extremely helpful. My boat is back on the Bosphorus running smooth. Teşekkürler!

We maintain a fleet of luxury yachts in Dubai Marina, and our clients expect perfection. Marine Engine Service built us a custom supercharged 6.2L Mercury for a 42ft performance boat — 650hp on pump gas. The attention to detail was extraordinary: ceramic-coated pistons, upgraded oil system, blueprinted block. The dyno sheet was included in a leather-bound folder. When the engine arrived, our chief engineer (ex-F1 mechanic) inspected it and said it was "better than factory." That is the highest praise I can give. Shukran jazeelan.

G'day from Down Under! Yeah, shipping from Poland to Australia took 3 weeks, but mate, it was worth every day of waiting. The Ford 302 went into my classic Haines Signature and now she absolutely rips across the Broadwater. The engine was beautifully dressed — painted, balanced, and ready to drop in. Even the dipstick was installed (sounds small but saves time). Dariusz answered my emails at weird hours due to time zones, never complained. Fair dinkum, best engine supplier I've dealt with. And no, the engine doesn't spin backwards because it's from the Northern Hemisphere 😂

We have a short boating season on Lake Ontario — basically May to October. I signed up for the Complete Care maintenance plan and it's the best decision I've made for my boat. Dariusz's team winterizes in October, commissions in May, and does the mid-season 100-hour service in July. They keep digital records of everything: oil analysis, compression tests, photos of wear items. When I sold my old boat, those records added $4,000 to the resale value. Now I'm on my second season with them on a new Cruisers Yachts. Highly recommended, eh!

The engine is excellent, really strong and well built. I use it in my fishing boat in Guanabara Bay. The only problem was Brazilian import taxes — I had to pay 60% extra on top of the price, which was a shock. But Marine Engine Service warned me about this before I ordered and helped me fill out the import papers correctly, so at least there were no delays in customs. The engine itself is 5 stars, but the tax situation in Brazil is rough. Obrigado Dariusz, maybe one day you open a warehouse in São Paulo!

Amigo, this shop is incredible. I shipped my blown Chevy 5.7L from Baja California all the way to Poland for a rebuild because the local shops in La Paz quoted me crazy money and couldn't guarantee the work. Dariusz sent me photos of EVERY step: the cracked piston he found, the cylinder bore measurements, the new camshaft, the valve job. When the engine came back, it looked brand new and came with a dyno certificate showing 340hp. I've run 150 hours in the Sea of Cortez since then, including some long runs to Cabo. Zero issues. Gracias, hermano!

The South Atlantic is not gentle. We fish commercially off Cape Town and our Volvo D4-300 is the heart of our operation. When it started losing coolant, I thought we were finished for the season. Marine Engine Service did a full rebuild — new head gasket, pressure-tested the block, replaced the heat exchanger tubes. The turnaround was 3 weeks including shipping both ways. Since the rebuild, we've done 400 hours in some of the roughest seas on Earth. The engine doesn't miss a beat. Dankie, truly world-class workmanship.

In Russia, winter is serious business. Temperatures in St. Petersburg drop to -25°C and most engines simply refuse to start. I ordered a Cummins QSB 5.9L with the cold climate package (block heater, arctic coolant, heavy-duty starter) from Marine Engine Service. Dariusz actually called me to discuss the exact specifications — he recommended a 5kW block heater instead of the standard 2kW because of our climate. He was right. My boat starts instantly even in January. The engine is installed in a 12-meter patrol boat for the Neva River. Spasibo bolshoe, otlichnyi produkt!

Sure lookit, I wasn't expecting much ordering an engine from Poland to the west of Ireland, but by God was I surprised. The little Evinrude 30hp is for my father's old currach that we restored together. The engine arrived in Galway in perfect nick, and Dariusz even included a bottle of 2-stroke oil as a gift — class touch. We took her out to the Aran Islands last weekend and she started first pull every time, even after sitting in the shed for a fortnight. Fair play to ye lads, grand job.

Living in the Azores, everything is difficult to get. We are in the middle of the Atlantic, 1500km from mainland Portugal. I needed two transmissions for our fishing fleet and nobody in Lisbon could deliver in under 3 months. Marine Engine Service had them in stock, shipped to Ponta Delgada port in 10 days, and the price was better than anything in Portugal. The ZF gearboxes are running perfectly on our two trawlers. Dariusz, if you ever visit São Miguel, you have a fishing trip and dinner waiting for you. Obrigado!

Precision is important to us Swiss, and Marine Engine Service delivered exactly that. I purchased a Volvo Penta V8-380 and paid for their installation supervision package. Their technician flew to Geneva, supervised the removal of the old engine, checked every measurement with calibrated tools, and verified the shaft alignment to 0.002" TIR — tighter than Volvo's own specification of 0.003". The installation certificate they provided is now in my boat's permanent file. Very professional, very precise. Exakt wie versprochen.

Yes, Austria has no sea. But we have the Danube, and my 9-meter river cruiser needed a new heart. I found Marine Engine Service online and thought "Poland is close, let's try." The Ford 302 Stage 2 is absolutely perfect for river cruising — tons of torque at low RPM, which is exactly what you need on the Donau. Dariusz found this amusing ("an Austrian captain!") and gave me a small discount. The engine runs so quietly that passengers don't even know it's diesel... wait, it's gasoline. Anyway, it's great. Danke schön!

Website is good, ordering is easy, price is fair. I sent my ECU by post from Tallinn and got it back in 5 days with a custom remap for my Yanmar 4JH4-TE. The engine now makes 65hp instead of 54hp and the torque curve is much flatter — perfect for the Baltic chop. Dariusz emailed me the before/after dyno graphs in PDF. Everything digital, no paper waste. Very modern company. Aitäh!

We operate 4 pilot boats in Riga Port and need 100% reliability. Marine Engine Service signed a fleet maintenance contract with us — they service all our engines every 250 hours, keep spare parts in stock for us, and provide 24/7 emergency phone support. Last month we had a coolant leak at 2 AM on a Friday. Dariusz answered the phone, diagnosed the issue, and had the parts couriered to Riga by Saturday noon. That kind of support is priceless in commercial shipping. Paldies, excellent partner.

Good quality brake kit for my boat trailer. I live near the Curonian Spit and tow my boat every weekend in summer. The old brakes were completely rusted from the Baltic salt. This new kit from Marine Engine Service is stainless steel and much better quality than the original. Installation took 2 hours with basic tools. The price including shipping to Klaipėda was still 30% cheaper than buying locally in Vilnius. Ačiū!

Malta is small but we love our boats! I put this LS 5.3L in a 21ft center console and it's absolutely mental — 475hp in a small boat is like riding a missile. The engine was perfectly dressed when it arrived: chrome valve covers, aluminum intake, serpentine kit already installed. Dariusz even set up the throttle linkage for my specific control box before shipping. Customer service is better than anything I've experienced in Malta or Italy. Grazzi ħafna, my boat is now the fastest in Marsamxett Harbour!

I keep my Princess 50 in Limassol Marina and use it only 3 months per year. Marine Engine Service handles the full seasonal cycle: winterization in November, spring commissioning in April, and the mid-season service in July. They coordinate with my marina manager so I don't even need to be present. Last season they found a failing raw water pump impeller during the spring check — replaced it before it could overheat my engines in August heat. That kind of proactive care saves thousands. Ευχαριστώ, see you next spring!

I am the captain of a 65ft Sunseeker based in Port Hercule. Our owner demands perfection — nothing less. Marine Engine Service built us twin supercharged 6.2L engines producing 700hp each, with custom exhaust manifolds to fit our tight engine room. The finish work is extraordinary: every hose clamp aligned, every wire labeled, every surface polished. When the owner saw the engines, he said they looked "like jewelry." That is the standard we require, and Marine Engine Service exceeded it. Service impeccable, communication discrète et professionnelle. Merci.

Hvala Marine Engine Service! My old Mercruiser 4.3L died in the middle of Boka Bay during tourist season — disaster for my charter business. I shipped the engine to Zaton and Dariusz rebuilt it in 10 days. Not only that, but he arranged a technician to come to Kotor and install it properly. We were back in business before I lost any bookings. The rebuild cost half what a new engine would cost, and it runs better than when it was new. These guys understand that for us, the engine IS the business. Hvala puno!

Quick and easy. I needed a bunch of maintenance parts for my Yamaha outboard — impeller, thermostats, gaskets, lower unit oil, spark plugs. Marine Engine Service had everything in stock, shipped to Piran in 2 days, and the total was €40 cheaper than the local Yamaha dealer. The parts are genuine, not cheap copies. Website is easy to use, Dariusz answered my question about oil viscosity within an hour. Hvala, will order again for sure!
