1998

Hey guys and gals, recently purchased a 1998 challenger 1800 with twin rotax 787 engines. I’m fairly pleased with the boat and have had it out a couple of times now. I want to be able to use the boat for longer day trips without the sound system killing the battery and leaving me stranded on the...

Looking for a used mpem for 98-99 challenger or speedster with key. If anyone has had their MPEM replaced. I'd be interested in dissecting the old mpem board to learn how to repair it even if key is missing. The old owner of mine DESTROYED the one they fried due to jumping. Part # 204470155

My 951 GSX sucked up a bunch of weeds and overheated and took on a bit of water. I was w able to rectify the issue and get it back on the water for a short duration before it dying and unable to start back up. Since then I haven’t even gotten a beep from when I put the key on or hit the start...

I just inherited a 1998 xp limited and threw a new battery in it. The key has a faint beep (1/50 I get the loud standard double beep and then a solid alarm sound maybe 30 seconds later). When I click the start button, I get a repeating solenoid click. I have tried the sketchy way of putting a...

Hi. Summary: 12v low on display...won't start in water...started on trailer then backed into water...kind of ran, but not to standard max rpms. Compression is fine at ~145. Okay, so, checked fuses in rear electrical box. One 20amp was okay, the other 20amp was blown, the third fuse was fine...

So i recently purchased a 1998 Challenger 1800, with the intention of storing the boat in the garage. When storing the boat, there is a definite smell of gasoline. I am not worried about ignition, more the usability of the remainder of the garage (as it is meant to be my home gym). In was...

So I took the ski out the other day, everything was running fine for about 40 mins. on the lake. It then started bogging at half throttle and wouldn't go over 20mph. RPMs also skyrocket to 6-7k. It was pretty choppy out there and took a beating. Initially, I thought it was something with my fuel...

Hi All, My first post here. I am in the process of rebuilding my engine after a big end conrod bearing failure.. It is the first time i have rebuilt an engine and i have learnt a lot from reading the manual and online etc. Finally the engine is on the mend again and i have just sealed the...

Multiple issues. This is a 1998 SeaDoo GTS. First, I just replaced the mpem because it was blowing the 5 amp fuse. When I connect the lanyard, I hear two beeps, but get nothing when I hit it he start button. I ran a multimeter and can clearly see that the solenoid is not even activating (I took...

I just bought a 1998 Seadoo Speedster and it is missing the driver armrest in red. I have searched the internet and no one seems to have the part. Does anyone know where I can buy this part new or used? Are there any guides on how to make a replacement part? Any help is appreciated. Thanks.

Howdy! I am a newb, which is daunting. but, I have a question. I am looking at a 1998 seadoo jetski GTX Limited - my question is, how well will that until and that age work in high altitude with two adults and a child on it? Would it still haul? Or am I expecting too much from something 16 years...

Ok so I am out of ideas on this one. I have a 98 speedster, the twin with 220 hp. I have had all kinds of problems with this boat and now I have a new one I cant figure out. On my RH engine, the Aft cylinder is dead. I can pull the spark plug lead off of it and it will keep running, if I pull...

So I bought a couple of seadoos 2 yrs. ago. Last summer my mother (crazy) in law wanted me to leave them at the cabin to play on, stupid me I did. The next day they brought them home to me and told me, " I got to the middle of the lake and it flipped over on me, I couldn't get it flipped back...

I found a 1998 GSX Limited a guy wants to sell for $450 NO TRAILER. It needs a top end rebuild. He took care of this jet ski along with a 2000 GTX like they were his babies. Garage kept, covered, maintenance every year before and after summer. Has a bit of hours but taken care of to the max...

Hey everyone, I was hoping to get some clarification on what might be wrong with my 1998 GSX limited ( i believe it is the 951 dual carb motor). I just bought this ski at the beginning of the year, and out of the water it is fine, but after i took it out last weekend, i noticed a white grease...
