You should always align a seadoo driveshaft when an engine is removed because an unaligned driveshaft can cause all sorts of problems. Vibration, carbon seal wear problems, leaking, jet pump bearing problems, etc. On another note, in my experience, if the engine mounts are left bolted in the hull and a engine is removed and replaced, the engine is generally pretty close in alignment. However, I would still fine tune it to get it near perfect.

@EastCoastAntics12 жыл бұрын
Thanks. You would bore a block if the bore is distorted or there is deep scoring or gouging. Yes it needs oversized pistons and rings if bored depending on how much it needs to be bored over (+0.5, +1mm, etc.). If it's been bored already and at its service limit it would have to be sleeved or you'd need a new block.

@EastCoastAntics13 жыл бұрын
Thank you. That's awesome! Glad I could help. Sorry I haven't gotten a chance to do a video on the timing yet. Basically to check timing you need to use the starter to turn the engine over. Put a compression gauge in one of the cylinders and using the allen bolts on the cam sprocket move them until you are around 145psi. To do this you would use the cam lockout tool and spin the bolt on the supercharger either clockwise or counter to get to the desired psi (145). That's a perfect starting. Recheck after the rings are broken in and you're good to go.

@@EastCoastAntics1 thanks for the quick reply. I was using a flat shaft inserted into the slot on the end of the balance shaft and turned everything over with a wrench. The pressure I feel isn't consistent. Only thing I can think of is that I'm feeling the pressure of the valve springs.

@@bjensen64 yes that's the valve springs since they will load up and then unload depending on what stroke they are on. You generally notice the same thing when turning over the engine by the supercharger if your ski has one. If the engine spun over before the heads and cam timing installed you should be good as long at you checked that the cam moved freely in the head before installing all of the valvetrain. Also making sure timing it correct and the cranks not stopping and no longer turning over. That would indicate valve interference. .

Everything is spinning, feels smooth but definitely feel the valves loading and unloading. This engine is supercharge but I inherited it after it broke both exhaust valves on number three and I dont have experience with a 4 tec prior to thos motor. Thanks again for the feedback.

@@EastCoastAntics1 I recently purchased my first machine and I got absolutely blindsided. Took it to the lake and within 4 minutes the machine had blown up. I’m just wondering if my engine is some how salvageable or if I need to spend the 6-8k it’s probably going to cost to put a new motor in

@@SomeMikeGuy ok so what was the problem with it? You need to check all the parts based on service manual specs and see if they are reusable.
