Well my father in law got this thing for $50 put a new battery in it and he went out on the Creek called me and said it was sinking he got it back to the house and tied off to shore line woke up next morning it's sitting on bottom water in hull up to top of rear ebox salt water mind you so it burnt POS batt terminal off solenoid and battery I replaced the terminals on wire cleaned up connections got another new battery plug in lanyard got two beeps push start button turns over fine so pulled plugs shut fuel off and turned over in small burst till fuel oil mix stopped fogging out the plug holes put plugs in turned fuel on still won't start so I checked the plugs no fire so I clip the ends of plug wires still nothing checked white wire going to coil it pulses the test light when cranking all other wires have power in rear ebox fuses are good so I replaced coil and I get a weak spark when grounding plug to block but nothing when I put the test light in the plug wire and I have read that the 800 has to have a strong battery could anyone more knowledgeable then me tell me what I should do next other then sell the POS

Welcome... but don't blame the ski for letting it sink in salt water. (Seadoo's are not rated to be left in the water)

Anyway... yes... the 800 does better with a nice strong battery. Mostly, it's just to get it to crank over. (high compression) Put a meter on the battery and crank it. If the voltage is staying above 10.6v... you should be fine.

Since the electrical was wet, with salt water... all I can say is to flush it well with fresh water (even the conections)... let it dry, and make sure all the electrical connections are clean. Needless to say... disconnect the battery first. Since you get 2 beeps... the MPEM and the CDI are talking to each other... and with a new coil... you should have a stronger spark.

Oh... make sure you pull all the fuses, and check the contacts. They have a tendency to quickly decay with salt water.

And finally... if you want answers quicker... please use punctuation. In this forum... all we have are our words, and trying to read a post without punctuation makes it hard to follow.

Thank you. Sorry for being iliterate. Could water have gotten in the carbs? Like I said I took the plugs out turned fuel off and cranked till fuel and oil stopped fogging out of the plug holes. Would that be enough to get water out of the carbs?

Any water in the carbs would flush through. BUT... if water got back into the engine... then the plugs may be wet.
