I have a 2002 gti that I recently got. So I just noticed some oil in the hull. Not much but just enough to be noticeable. Like I said I just bought this ski and have only had to add oil to it once. There was never oil in the hull until after I added oil that first time. I will say I accidentally filled it to the top, to the point that some overflowed. I know rookie move lol. But can the oil in the hull be caused from overfilling? I did take it to the shop the other day to get a couple cosmetic things done to it (new traction mat and seat wrapped) I asked the mechanic about the oil in the hull and he said will inspect. Upon picking the ski up the mechanic said he searched for a leak and did not find anything, then proceeded to say it's normal for a older 2 stroke ski to have a little bit of oil in the hull. I searched for a leak as well and found nothing. I just find that statement from the mechanic to be a bit weird and the fact that it wasnt in there before I filled it up the first time. I do check oil level before each time I take it out and I never lose oil. Meaning it could sit for a week and the oil level appears to be the exact same. I may be overthinking this but just doesn't seem normal to me. Any advice would be appreciated.
