was on a friends boat last weekend and i noticed a sheen on the water when engine was running, none in hull, none in belly pan, just when running.
motor appears to have a diaphram pump and a vst, like my yamahas, my question is if the diaphram is bad will gas dump thru it into crankcase unspent and out exhaust ? or is there another issue going on .
thanks in advance
