Hello all .. I just bought a jon boat that came with a 7.5 Mcculloch motor. It runs great but I’m not seeing it pee out of a tell tail. I seen someone’s post on here that these outboards only sprits out a lil water at exhaust .. is this true? I don’t want to fry a good motor .. also I need help determining the year of it .. the serial# is 68600712-3844.... can any one help me? Thank you in advance

Should be a 68 low profile motor. They only spray a mist out of the idle relief holes while idling. I would recommend a new impeller for it. Most people don't replace them because they do not think they are available. A quick internet search will find them.

Thank you so much. I found a new one on eBay . Now I was out at the lake yesterday and my 7.5 smoked a little and cut off.. would this be a bad sign? After it cut off I only used my trolling motor to fish and get back to the dock.
