Rebuilding your PWC engine.
   There are many advantages such as; no upfront core charge, you know your engine is the correct one for your PWC, all serial numbers will match and you don't send a good core and get back a patched up saltwater core.  It is guaranteed that you will get your same engine back, rebuilt to our engine specs.


Platinum pwc engine rebuild .

Our Platinum rebuild has been our flagship for many years.  We start with rebuilding the crankshaft with new rods, pins, bearings and thrush washers.  Trued to 0.001" or better and verified in your engine cases for proper fit and runnout.  Fitted with Teflon coated seals for less friction and longer life.  The cylinders are bored and fitted to molly coated pistons.  After the cylinders are bored, we give the ports a very aggressive (3 stage) chamfer. 

All of our engines run the same compression (within 1 or 2 psi) as the engine was originally designed for so you keep the power and don't lose the reliability.

Final finish is with a hi temp, oil and gas resistant gloss black engine enamel. 

The difference Is the attention to detail and the Quality of the parts. 

These aren't SBT remans and we don't and won't use SBT parts in anything we do.

Take pride in your ride with our Platinum rebuilds.

Our platinum engine rotates easier and produces less friction. This results in less heat, less drag, and more Horse Power, while increasing the dependability.

 All of our Platinum engines are built to last and we stand behind them, with a 2 year warranty on parts and craftsmanship. 

Accepting credit cards through pay pal, right here on the web site.  It's the safe and secure way to pay online.
