welcome to the forum,
i'm a fellow Cape Corallian.... off Chiquita and CC parkway... where are you located.?
also... I'm 99.9% sure I have a good mpem, it came off a 98 spx if I remember, I was keeping it as a spare for my 96 xp but I just sold it, so I no longer need a backup...
if you want we can maybe hook up and you can swap them out, it will at least tell if the mpem is the problem or not... but we might want to wait for somebody that understands mpems better to confirm that this procedure makes sense (swap mpem's vs looking at other sources as to why the fuse is blowing), I'd very much rather NOT have your ski blow my mpem
ps.. the question itself should be posted in the 2 stroke section, 99% of the regulars don't visit the meet & greet pages
I also might be able to offer some general help, i'm no mechanic by any stretch, but I know just enough to be dangerous
i'm sort of ski-less right now, the only one I have left is up for sale,
but it looks like i'm going in halfsies on a boat next week, but if you'd like to get out on the water, I might be game.
