    1997 GSI MPEM Problems

    I have a 1997 GSI and I suspect the MPEM is bad. I can't get the engine to turn over using the start switch. I checked the switch and have 0 ohms when pressed. I checked the DESS post and it I get 0 ohms between the black wire and the black/yellow wire with the tether installed and infinite...

    Sea-Doo GS GSI GSX (RF DI & LTD) RX (DI) '96-'03 OEM Boarding Step 295500693 $150

    Found this the other day and purchased one as for the price it's a steal (I'm from the UK & Only one place in the country sells this for just shy of £300/$425) So was a no-brainer for me to import it - I've never seen a GS or RX doo with a step on in this country (that means nothing though lol)...

    1997 Sea Doo GSI

    Hey guys quick question for the sea doo community :) We recently went to look at another jet ski a 1997 GSI. It's really clean everything on it works and is functional on it, but the compression in each cylinder reads 120 for both. Which seems low. What do you guys think? Let me know! Thanks

    97 GSI Power Issues

    My 97 gsi bogs off while accelerating and maxes out around 4K RPM EXCEPT when I hit a wave with a good jolt and the RPMs then go up to around 5.5+K (which it then appears to be delivering full power). This additional power will last for a second or so (unless I hit another wave). It seems that...

    1997 GSI - Keeps losing electrical power??

    Hey there... I've tried searching this on past threads with no luck. I have a 97 GSI that randomly keeps losing electrical power. It's only been in freshwater, has approximately 170hrs on it. I've narrowed down to something in the rear electrical box, located near the battery. I would assume...

    MPEM Problem - 1997 GSi

    Hello, I recently bought a 1997 GSi Seadoo and have had it running nicely (The engine is in mint condition). But the problem I have is that when I connect the lanyard to the DESS post it doesn't always beep (or even allow me to start the engine or use the VTS). Through tempering with the...

    Ok so I just bought a 98 GSX limited and the fuel gauge doesn't work. The shop that summerized it for me said the electrical module box that's up in front of the ski is bad and it's not sending a signal to the digital gauge up top. Is this true or is it the digital gauge I need to replace...
