mpem

95 XP does not crank with start button, dash turns on and then turns off It DOES crank by shorting solenoid, and also DOES crank on its own (only for a second) when key is attached, and only when grounding the MPEM to the stator for the first time, otherwise the stator connector must be...

If anyone has one of these i would be interested in buying. I have a RXT 215 2005 model with broken MPEM and need a new working one. Part number is 278001724. I heard that i need the 2005 or 2006 one because T.O.P.S implementation is different in those than older ones.

The MPEM 5A fuse blows whenever I attach the stator harness to the mag cover Engine turns over by shorting the solenoid Disconnecting two yellow wires from rectifier still blows fuse, disconnecting red wire from rectifier still blows fuse One of the 5A fuse terminals (But not both) has...

Hey all, are there any work-arounds to replacing the entire MPEM? Which component(s) generally blow? And can I order them? My little sister thought it was ok to jump/charge the boat battery while the car was running. Just trying not to spend $500 on the entire thing. Thanks!

Hi there, As we know these MPEMs are no longer available new and almost impossible to find working and used. We also know they are needed for the boat to run. With this being said, I read on a forum that I could swap My 95 657x sportster MPEM with a 95 ski with a 657x. Does anyone have any...

Hi there, MPEM is toast on my 95 and as you know impossible to find. I saw in another post it is possible with the 657x engine to swap an MOEM with a 95 657x PWC. Would anyone have any ideas how exactly this could be accomplished? I just purchased one off eBay but would like to make sure that...

I read many forum's but once people fix their issues they don't follow up on it worked out or any details on any other issues they worked out. So I am sharing my experience . My issue when I bought a used 1996 sea-doo GTI 717 5865 . I own a lakehouse so I have a advantage of trial and error...

Hi everyone happy I found this forum and clearly see alot of communication and helpful individuals on here. I have a 99 speedster with the twin 787s and have lost spark to my starboard side engine. I have tested every thing including even switching everything from one engine to the other no...

Hello everyone, New to the forum and I've been diagnosing some issues on my 2001 GTX RFI so I thought I would share. Bought the jet ski and it was running a little rough and fouling plugs so I cleaned the RAVE valves and it was running like a dream. Before taking it down to my house on the...

Hello all, I am hoping to get some help on how to fix my 2004 GTI RFI Sea Doo. I have tried to diagnose the wires my self but fear I am doing it wrong. So my Sea Doo is a Sea Don't. It is getting not beeps when I put the key on. I have read through other forums on here and have tried the tests...

I have a bad mpem in my 1995 speedster which has the twin 657x motors. I have seen where some people change the mpem to using two mpem. I purchased the two aftermarket mpem units and am working on wiring them to my harness. I have figured out some of the wiring however I am not 100% sure I have...

Hey guys! 3 days ago I came back after a great day on the water. I was so tired that I didn’t realize I left the DESS key on the post and the battery switch ON. I realized next day so I put the key away and plug my 2amp battery tender. After 12hrs Electronics work so I assume I was ready to...

Hello, I just picked up a seadoo xp 787 1997 for cheap with a trailer since it was hydrolocking with oil in the PTO cylinder. I was able to get it running today off starting fluid, put it in the water and let it run for a while to burn out the oil. It worked pretty well and the ski restarted...

Last time out on the water, when I would turn off the engine, intermittently upon putting the key back on the high temp LED would flash a few times, then whole info dash would turn off... take out key and try again, eventually it would just work as normal. Now it seems to be indefinite. Will not...

Hello, I am new to the Seadoo and PWC's and any input will help. I just bought a 2000 Seadoo GTX RFI, in very good conditions, but it is not running - at least I don't know how to start it. The ski has a brand new motor SBT ( 3.8 hours- some premix it is still in the tank after the brake in)...

So I just replaced the MPEM on my 01 gti, the machine fires right up and idles beautifully, putters around fine and will even cruise up onto plane, but if I go harder than 1/2 throttle it beeps and shuts off. Fires right back up after and runs but again cant get to WOT. Any thoughts

Recently bought a 2000 seadoo rx di....when I plugged everything into the mpem and replaced fuse in rear electrical box the mpem started smoking at plug 2 pin 25 and 26. The plastic on the mpem has started melting....the vts is unplugged aswell as 6 pin at stator. I have tried testing which fuse...

I got this part with a sale, it is an MSD ignition, I bought an XP, 1995 with the 720, he said he had it working with this, I cannot identify it. Anyone know?

Thanks to the members, great advice here. I've been lurking for too long, it's nice to be a member. So, I've got a 97 GTX. When I connect the battery it immediately tries to start. My battery was dead and I jumped it using my boat battery. The boat battery was in the driveway and not...

So, I need a new one of these or can these be repaired by someone? Does anyone have a working one for sale or any idea where I can find one that isn't seemingly overpriced. I can't really trust the ebay sellers because most don't say it is working and they are all a bit outrageously priced...
