Hello and thanks in advance for any advice. I bought a 2000GTX RFI with the motor in boxes (appeared to be a seized crank but was a piece of ring caught in cylinder) so i purchased a BRP short block, installed and was on the water.
The machine ran great with the exception of 12V low alarm. After ejecting a buddy from the back I shut it off, it wouldn't start, had boat tow it back to dock. I changed the battery and all was good (except 12V low) for about 15 minutes until it lost power and wouldn't rev over 2000 rpm. I changed plugs thinking I fouled as I am running 500ml Sea Doo full syn oil (dealer recommended amount)in full tank as well as injector this didn't fix anything. Rear plug appeared to have quite a bit of oil and gas, front plug looked good and dry.
When out of water I checked compression 150/147, spark good, pulled plugs and cranked engine - no water, removed raves they were oily but kind of milky with a couple bubbles that appeared to me like water. I also followed the 3 yellow stator wires back to regulator and found connectorwasn't mated entirely (oops). After a full charge I started it on hose and it ran fine revved up and no more 12 V low alarms.
Next was the water test, my buddy launched it for me as I was busy and said it seemed to rev up pretty good and got to 25mph and maybe a minute later went back to 10mph and 2000 rpm. He did not notice a 12 V low alarm.
Next I will check stator, regulator, fuel lines whether they are grey (not sur if this was rfi issue) and the spray pattern of the injectors.
What else am I missing, am I getting water in engine? cracked exhaust?? Any help is appreciated as lake testing is tough an hour away.
Thanks
