I've heard of the cooling mode. Is that in the manual? If not where can I find instructions for it?
Thanks,

I just got the battery in and checked the compression today. I found 60 psi on cylinder 1, 140 on cylinder 2 and 180 on cylinder 3. Checking the plugs, it appears that cylinder 3 has not been firing and it was full of oil. Thant may explain the high reading on 3 but cylinder 1 obviously has a problem. I'm trying to decide if the old ski is worth fixing up.
Question: Is it OK to bore cylinder one to first or second oversize to repair damage without boring the other two? If not is it OK to re-sleeve cylinder 1 and go back to the original piston size with out doing anything to the other two?
Thanks,
willno

Just got the battery in and it's not good. Ran a compression check and found 60 psi on cylinder 1, 140 psi on cylinder 2 and 170 on cylinder 3. Plugs look like #3 hasn't been firing at all and full of oil. Probably why compression is high there but #1 definitely has problems. I checked the spark and I got a visible spark at all three. I checked the injectors and all three had 20V when cranking. don't mind rebuilding the motor but I'm concerned that the EMM may have problems. Is there any way to check that? I found a copy of the KADIAG software but I don't have anything that will run it anymore. Any advice?

Thanks,
willno

Looks like your good emm wise. Cranking voltage is 20v, running voltage is 45.
Make sure the injectors stay on the cyl they are on. There is info in the emm that is related to that injector. If your going to take them off the head, make sure you label them.

Thanks for the advice. Glad to hear you think the EMM is good. I guess I'll have to pull the motor for the rebuild or can that be done with the motor in the boat? I have a manual but it's hard to use since they keep referring to the KADIAG s/w.

I also have a bad display unit on the dash. It doesn't even light. Does anyone rebuild those?
Thanks

If you decide to buy a new info gauge, I have one for a 2000 STX DI I'd be willing to sell.

No, you really need to pull the engine so you can split the cases and check and clean the crank bearings, and since you are doing that, I would put new bearings and seals in the driveshaft bearing assy and oil pump adapter that is in the stator cover.
