I have a Yamaha 6hp fourstroke. The engine is approx 3 years old and is "as new" with very little usage. While having the engine serviced recantly we found that water is getting into the sump. Both the powerhead-to-leg and cylender head gaskets have been replaced, however, the problem still remains. My mechanic has run out of ideas, so if anyone has experienced this problem I would gladly like some davice.
