What makes this a real Premium engine rebuild?

We won't slap a higher price on the same box and call it a premium like some of our competitors.

We start with rebuilding the crankshaft with new pins, bearings and thrush washers and of course new rods with 4 oil feeders each. 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 with Wossner pistons forged.

Our engines rotate easier and produces less friction. This results in less heat, less drag, and more Horse Power, while increasing the dependability.   No shortcuts, no false claims, no bull, just perfection and attention to detail.

All of the machine work is done in house here at Full Bore and exceeds factory quality specifications. All of Full Bore rebuilt engines are built with new top quality parts, pistons, rings, pins, clips, rods, bearings, gaskets and seals. These aren't SBT remans and we don't and won't use SBT parts in anything we do. We only use parts that over the years and have proven them worthy of being in a full bore engine. Our engines rotate easier and produces less friction. This results in less heat, less drag, and more Horse Power, while increasing the dependability.   No shortcuts, no false claims, no bull, just perfection and attention to detail.    

All of our engines are built to last and we stand behind them. 

Our Premium rebuild comes with a 2 year warranty.

  Our rebuilds are rock solid and out last and outperform the competition.

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.


Scheduling and order of work done is determined by payment received or deposit date.

Without payment or a deposit you are not on the schedule. 

The reason for this policy is simple, we are a small family operated business and we can't afford to invest thousands of dollars into customers engines and have them sit on the shelf until spring.

Engine rebuild Deposit

Please note deposits are for engine rebuilds not top end kits or cylinder repair.

 $500 deposit or payment in full is require before starting your engine rebuild.  Immediately after receiving the deposit or payment we will put you on the schedule.   Balance of rebuild will be due upon completion.

No Core charge!!!

We don't charge a core charge because we are rebuilding your engine. If part of you engine core isn't rebuildable such as a hole in case we have many core parts in stock and would only charge for what is needed and only after contacting you first.

Core with hole in case

This is NOT a good core.

severely corroded engines may be considered unserviceable!!
