Hi all! I have been pulling my hair trying to figure out what's wrong with my 150 hp 1988 Evinrude xp vro. On sat I was running it in Lake Havasu and it ran like a charm all day. Sun morning I took it out again. The only thing different that I did was add tc3 oil to the oil tank. It ran alright for a few minutes then lost power when it was in gear. In neutral it runs great. When I put it in forward gear it would start to lose power. Sometimes I would leave it in the full throttle position as it barely moved 10 mph and then all of the sudden it would get its full power and take off...and then lose power. I changed the spark plugs (they were all oily) and checked the spark to all 6 cylinders...all seemed good. The primer bulb was also pretty firm. What can this be? Is it the carbs, fuel pump, or power pack? If so then why is it fine in neutral? Please help!!! Thanks, Nick
