HI. new to seadoo boats (new to boats period)

picked up a 1999 seadoo challenger 1800 twin 787 as a project.

guys said it had been sitting for about 2 years.

both engines have great compression

first time i turned them on seemed as they were in WIDE OPEN THROTTLE

bought new carbs for each engine

first engine idled a lot better, the other engine did the same (WOT)

i swapped carbs again and they were not as bad.. but still seemed as if they were reving too much for idle.

i took it to the water... (lots of smoke but it kinda went away after a while)

loud beep which i would turn off by pressing the bottom right yellow button

the small black pressure valve on one of the engine was leaking a little bit of water from the bottom

i got the boat to do 12mph full throttle.

i did not really pay attention to the rpm or anything else other than my boat sinking (very new to boats)


any help or suggestions would help.

Hello all. I bought a project 1999 challenger 1800. twin 787. the boat needed lots of work, river side engine turns just fine. Passenger side engine doesnt even turn, starter solenoid clicks when i press and depress start button. I switched starter solenoids and same thing happens.


while holding the start button i tapped on the starter with a hammer... engine didnt turn still but something starter to burn right under the starter 0_o smoke came out and all..

starter and power cable to starter are both hot now.

just wanted to introduce myself and hope to get some much needed help for my new purchase. 1999 seadoo challenger 1800
