I noticed a mention of excessive smoking when discussing the props. I have a s/v Gulfstar 36 with a prop that has no markings. At the higher end of the RPM range I get backwash on my transom of un burned fuel. At about three quarter RPM very little is on the transom.
My mechanic says no problem run the engine. Tired of cleaning my rear end.
Am I missed proped?
Thanks in advance.
