Just bought a 98 Speedster and one motor overheats HELP!!

[sxsuperfly]

Hi Everyone,
I just bought my first jet boat after years of running outboards and have tryed to run the boat at the lake twice now with one problem after another. After extensive cleaning and rebuilding the carbs on both motors because the right motor would only run on one cylinder now the right motor overheats and makes the alarm go off (it is rediculously loud!!!!)
The starboard engine doesn't have any water coming out of the exit pee hole next to the jet pump when I hook up the hose to the lower flush inlet. Some thing must be plugged but I don't know how to unplug it. The port side motor has water coming out the pee hole just a few seconds after turning on the water. I'm new to these jet boats but if running the motors and flushing them with a hose under presure doesn't work to get water to come out of the outlet then what do I do next?
I tryed using the hose to force water back through the pee hole to back flush it but I couldn't get any water to go in with the hose turned all the way open!!! It acts like its plugged solid.
So far I've thrown alot of money, hard work and skinned knuckles into this boat and I just keep running into more problems and this one I don't know how to fix.
Any help/suggestions would be greatly appreciated
Thank you

Welcome to the forum. Sorry to hear about your problem. I think you're on the right track about the cooling system being clogged. You could try blowing compressed air in the "pee hole". If that doesn't work, remove the hoses one at a time and see if there are any clogs. If no luck there, try blowing the compressed air through the engine.

You may want to try posting this in the 2-stroke boat section of the forum. Others there may have some ideas on what you should try. Good luck.
