Hi just took out my seadoo today after putting it all back together. Just had a rebuild top end and barrels etc by someone else.
Started well and idled and ran well for about 20 mins pretty smoothly and all seemed good. Was running it in slowly and didn't rev it past 50%. However after a while it stated running rough at low revs. Splutting a bit and then problem slowly got worse. Then after stopping in the middle of the river and tried to restart it wouldn't fire and just cranked and spluttered. Got it going by holding throttle flat and cranking it. It fired and ran rough. Managed to head back to the boat ramp and on the way back it wouldn't idle but would surge. Had to hold the throttle almost flat stick and then back off as the power kicked in just to get back.
Seemed like a fuel starvation issue or running on 1 cylinder at low speed and 2 cylinders at higher revs?
Has old fuel and oil in it so I should probably start there by replacing that. Got back on the trailer and it still won't idle but runs at half stick and only under revs. Likely needs carby tune and fuel system clean out. But any tips welcome or any similar experiences - I'm keen to hear. Thanks in advance.
