After we receive your cylinders we will inspect them and determine what oversize pistons it will take to make the cylinders straight (usually 1st or 2nd over) then bore your cylinders on a boring bar, final sized with a rigid hone. The ports are chamfered in a 3 stage process to ease the rings back in, including a final hone to extend engine life, and improves performance. The kit is returned to you with everything needed for your top end rebuild
No more trips home from the machine shop without your cylinders because the pistons weren't big enough to clean it up. Let alone the fact you have to send those pistons back and order another set. We keep it simple and offer solutions for your top end rebuild and get you back on the water.

If your cylinders are already 0.040" (1mm) over, or need to go larger to clean up, the purchase of Wiseco or Pro X upgrade would be required or cylinder resleeving.
Boring a cylinder needs attention to detail, if it is going to be done right. Here at Full Bore we take every precaution to make sure it is right and will custom size to what your needs are. Our strict quality control policy ensures specifications will be met. The cylinder is bored, sized, and followed by a three stage chamfer to ease the rings back in and increase engine life, and final hone for the proper cross hatch.
12 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 Platinum engine rebuild now comes with a 2 year warranty.
