Certified in both automotive & marine specializing in performance.




We rebuild long and short block engines, cylinder heads and crankshafts and afterwards they are equivalent or better than new!  

RPM has been re-building engines for over two decades and our experience in engine rebuilding far exceeds our competitions’.

Our in-stock inventory of long and short block automotive, light truck and marine engines can expedite your needs in case you can’t wait for a full engine rebuild. 




Being avid long time boating enthusiast ourselves, RPM has 33 years of extensive experience in repair of inboard and inboard outboard engines.

Some outdated, obsolete or impossible to find  aluminum or stainless parts can be manufactured on site.

Rebuilt marine engines are run before delivery. Engines are leak checked and coolant temps and oil pressures are recorded before the engine reinstall.

Performance boating options include stroker and supercharged engines, camshaft and exhaust swaps and cylinder head/intake manifold upgrades.

Smaller Pleasure craft diesels such as Yanmar, Caterpillar, Detroit Diesel and Cummins are repaired/rebuilt on site.

Closed system intercoolers are surgically cleaned in our 4KW ultrasound cleaner.

Marine transmissions such as ZF, Twin Disc, Paragon are rebuilt along with the smaller Hurth sailboat trannies.

If it's boat related, we're your first call.
