Pulling the powerhead on this Nor-Tech Catamaran. This boat is equipped with four Mercury 450R engines. The port outside engine suffered a head gasket failure due to salt water corrosion, we pulled the powerhead to do a full replacement and get this client back on the water in time for some poker run fun!

Yes we know these are L6 engines, they have been flashed to make 450hp each

Micheal brought in his late 70s thundercraft for a transom replacement. Another shop attempted to replace the transom with coosa board but its failed due to poor lamination because they cut the back of the boat out instead of doing it the proper way. We split the decks and replace the coosa with proper marina grade Douglas fur ply wood and fiberglass as it was intended. After replacing the transom we repaired the outer transoms skin from the prior botched job and painted to match. This boat will now last another 25 years!

Testing another engine and setting timing before it gets dropped into its new home. This good used low hour 3.0L is going in a 90s ski boat, we should have the engine back in and ready for pick up within the next 24 hours!

A little REPOWER action this week! This wellcraft center console came in for initial diagnostics where we found the Johnson outboard had no compression on 3 cylinders. Our guest found a heck of a deal on this Yamaha 225 4 stroke set up, so we rigged the engine and control box along with new cables. Now this center console has a new lease on life and should last our guest another 15-20 years!

Another NanoXCel hull repair! This Waverunner had a small crack on the starboard side due to a roller style dry dock. We ground out the affected area, fiberglassed it with specialized components designed for these NanoXCel hulls. After applying the fiberglass patch we did a final coat of a specialized resin putty to fill any gaps or small holes. The final step was a full sand with 80 grit and a fresh coating of Super Slick 2000 to strengthen and reinforce the bottom of this ski.

If you have a waverunner that has a whole we can fix it! Dm us today to set up your appointment.

This guest brought in his Century Coronado Cardel for some initial diagnostics. He had just had a new motor installed elsewhere but we found an abundance of issues. The main issue was the incorrect camshaft and valve train were used upon assembly. This cause the cam lobes to wear and create internal damage. Our guest had enough and wanted the bad engine out. We upgraded him from a 7.4L Mercruiser to a 454 HO MPI set up which gives him more torque and horsepower with the reliably of multiport fuel injection! Now this boat is ready for the water and in less than 2 weeks time vs the 6-7 months it was with the other shop.
