Green sludge behind stator cover
2001 STX1100 DI, flashing "batt" light, BRAND NEW battery, so i checked all 5 coils' resistances and they were all outta spec. So i took the stator cover off anticipating to change it and found this green sludge, about 1-2 tablespoons worth.
The yamalube oil that i use is blue tho, so is this oil mixed with gas??

Probably an emulsion of water, oil, and starter drive grease.

Think this necessitates a front crank seal change?

I wouldn't just yet. Check the front plug to make sure it's not running lean, then check the front cover in a few hours. If it comes back, it might be the front seal. Have you had water in the hull? Could be water in the hull leaking past an improperly installed O-ring, mixing with starter grease or something.

Yea there was once a bit of water in the hull, so this sludge could be from then.
I just cleaned the FUUUU outta the stator w/ electrical cleaner seeing if just MAYBE the resistances would improve, but they didn't.
So Ima pick up another stator tomorrow assuming that one is good, hope that fixes the batt light, and take it off and inspect after my first days' ride.

A lot of the Ultra 150s had trouble with the battery light staying on, but the battery would charge and work normally. Before replacing the stator, are you having a problem besides the annoying light?

Other than me constantly being paranoid about the next time my ski doesn't start leaving me stranded??....
Last season with my freshly rebuilt EMM, I had to get towed in twice cuz I shut the ski off just to chill, than it wouldn't start again, just like it was a dead battery. Even tho the old battery is still reading 12.5volts as of yesterday, hasn't even been hooked up to a trickle charger either, just chillin in my room for the past ~7 months.

Check the engine ground near the starter, I had an issue with my 15f not starting and I cleaned the spot where the starter attaches to the block and where the ground cable attaches to the starter and it helped.

Yup already did that too. What a major PITA location that is with not enough clearance for a socket and ratchet, but with my trusty ratcheting open-ended wrench.... wasn't really a problem.
O yea, it also helped that I was able to get my entire head and left arm and shoulder into the hole the rear storage bin goes into so I could visually SEE the starter. Also made it pretty easy. But god I woulda loved to see a picture of the way my body was contorted into to fit into that hole lmfao
