Decent service, hard to reach
The work was fine, but getting someone on the phone to schedule an appointment was a nightmare. They need a better front desk.

Solid repair work but pricey
They really know their diesels. Fixed the injector issue on my engine perfectly, though the final bill was definitely on the high side.

Work took way too long
They had my boat for two weeks for a simple fuel pump issue. No updates until I called to complain repeatedly.

Fixed my engine issue fast
I was stuck with a boat that wouldn't start. They came out, towed it, and had it running by the weekend. Highly recommend.
