Pre-purchase engine survey on this beautiful Nordhavn 55, “What’s Next,” in Southport, North Carolina.

When you’re looking at purchasing a vessel like this, the machinery deserves a lot more than a quick look in the engine room. A proper pre-purchase engine survey is about getting a clear picture of what you’re actually buying before you sign on the dotted line.

We travel anywhere in the country to survey your next vessel.

Apex Marine Service specializes in long-range trawlers and passagemaker-style vessels, where understanding the entire mechanical package is especially important. Nordhavn, Selene, DeFever, Grand Banks, Hatteras and similar vessels are right in our wheelhouse — but our survey services aren't limited to trawlers. If it has an engine room, we're happy to take a look.

Whether the boat you're considering is 20 minutes away or 2,000 miles away, we can travel to the vessel and give you an independent mechanical assessment before you make one of the biggest decisions in the buying process.

Buying the boat should be exciting. Finding out what it really needs shouldn't happen after closing.

Another Nanni installed! 💪

This time, we repowered a really clean Valiant 50 with a Nanni N4.85 paired with a ZF V63 transmission, along with a Next Gen 5.5kW generator.

Another solid install completed by the Apex Marine team and another boat ready for many more years on the water.

We’ll also be at the Annapolis Powerboat Show and Sailboat Show this year and will be booking our winter engine specials while we’re there.

Another Nanni repower in the books—this time on a Grand Banks 36.

This was a fun one from start to finish. We tore out the original steel fuel tanks after finding rust holes in the tops, cut them apart for removal, and installed new custom aluminum tanks that fit through the salon window. While everything was apart, we fiberglassed in brand-new fuel tank supports, installed all new fuel lines and fuel manifolds, and built the fuel system from the ground up to ensure reliability for years to come.

The original Ford Lehman had reached the point where a repair just didn't make sense, so we removed it and repowered the boat with a Nanni N4.115 paired with a ZF 45A transmission. The new engine was brought in through the salon window, custom engine mount brackets were fabricated to adapt it to the existing beds, a new propeller shaft was installed, and the entire drivetrain was aligned and commissioned.

To finish it off, we built a custom wood panel to match the original interior so the installation looked like it belonged there from day one.

The best part? Every bit of this project was completed in-house by our team—from cutting out the old tanks and fiberglassing new supports to fabricating brackets, building the fuel system, installing the engine and shaft, aligning the drivetrain, and completing the finish carpentry.

If you're thinking about repowering your boat, give us a call. Whether you're replacing an aging engine or planning a complete drivetrain upgrade, we'd love to help with your next project.

We've got a lot of exciting projects in the works—bigger, better, and more to come. Stay tuned!

The Apex Marine team recently traveled to Myrtle Beach, SC to conduct an engine survey on this stunning Defever 52 Pilot House—powered by a pair of John Deere 6068 engines.

If you are considering purchasing a vessel, an engine survey is one of the smartest investments you can make before signing on the dotted line. Apex Marine will travel to wherever the job takes us.

Another Cummins coming out of a vessel. These aft cabin Sea Ray models make engine removals extremely difficult, but we have the tools, equipment, and experience to get the job done right.

A lot of work goes into this one moment. Proper preparation always makes the difference when it comes time to lift an engine safely and efficiently.

May the 4th be with you. And if your engine has gone to the dark side, you know where to find us.

Case in point—this valve seat dropped into the combustion chamber. All of that debris you're seeing is what's left of it. This engine came to us in rough shape and we are getting this owner back on the water with a full rebuild.

The Force is strong at Apex. 🔧
