1998 150 Intruder E150GLECD(model) G04375455(serial). Bought the boat just over a year ago. Runs great no complaints or issues. VRO was removed when purchased. Premixing 50:1. Here recently I have noticed a fair amount of oil sludge on housing where it pivots (sorry do not know the name of that part) Today I took the shroud and there was a small puddle of fuel in the lower front of the engine housing. Any ideas where the source may be and how to fix?
