I hope someone can help. I bought a boat 1977? (real cheap) for me and my boys to play with. It starts fine but the oil turned milky after about 2 minutes. I drained and filled and same thing. The pre owner had installed a new carb and it looks like he made his own gasket so I am suspect of his work. I then noticed a trickel of water coming from the right side of the engine below the intake but above the frost plug. It is toward the front of the engine. I drained the oli once again and sure enough it filled with milk. The water seemed to be picking up speed running down the block. I find it hard to believe it would be a cracked block cause it runs fine. Except for the self sinking feature. Ideas? and if so where can I get parts for this unit if I have to repace anything? I would just buy a new one but my boys love it 4 and 9...
