Welcome to Full Bore.
Full Bore offers rebuilt Sea Doo engines, rebuilt Yamaha pwc engines, cylinder boring, resleeving, and complete top end rebuild kits. Cylinder boring, resleeving and complete top end rebuild kits for Sea Doo, Yamaha, Polaris and Kawasaki PWC.
10 years ago we introduced our Platinum engine rebuild line with less friction, more power and longer life. Full Bore’s Platinum Sea doo engine line is often copied but never duplicated.

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 engines are built to last and we stand behind them, with a warranty on parts and craftsmanship. Our economy rebuild comes with a 1 year warranty and the Platinum now comes with a 2 year warranty.
