After about 10hrs on engine it started leaking oil around the seam between the lower and middle unit. After running at high RPM for a few minutes and then lifting boat out of water a large amount of "pinkish" oil (about 1/4 to 1/2 cup) oozes out around the seam. Dealer says it comes from the carb throats and runs down back of housing. He says no problem. I say something is definately wrong. Can anyone help?
