Sea Doo 787/800 and 947/951 require relieving the RAVE Valve if bored more then the first oversize as shown in our tech tips Page.

After boring the cylinders on a Sea Doo 787/800 947/951 or any other engine with a power valve, you must relieve the exhaust power (RAVE) valve for clearance or you will snag your rings and destroy your new top end. The old rule of standard bore and first over don't need the valves relieved doesn't always hold true. As things wear they tend to get closer and eventually they make contact even on std bore with high hours.

Send the valve only we do NOT want the plastic caps they tend to break in shipping.

***Note*** Rave valve mod gives you clearance for the freshly bored top end but it is also a high wear part with a reputation for failing with or without the mod and need to be inspected regularly for wear.

Comes complete with new Wiseco or Pro X pistons, rings, pins, upper bearings all of the gaskets (WSM) needed for a top end rebuild. Your cylinders are custom bored to fit.

If you already purchased a top end kit (from Full Bore) and your cylinder needs a new sleeve we will replace the sleeve part and labor for an additional $100 each, $150 for both on a twin cylinder and $200 on triple cylinders listed below.

Contrary to the common belief, you don't just press out a sleeve and press in a new one. Please don't wreck your cylinder trying. Besides installation they do need to be bored and sized after installation.

When shipping cylinders, pad them tightly with crumpled newspaper or dense foam, be sure cylinder (s) are secure and don't move freely in the box causing damage.

Don't forget to insure your shipment. If you keep your shipping receipt, you can check online to see when it is received on our end. Please send with signature required. When we ship your cylinders or engine back, you will receive an email with tracking info.

Be sure to include clear instructions of work requested, return address, and billing info, phone # and email address. If you have a pay pal receipt, please put a copy in with the cylinders or engine.
