    Question for Dhadley

    Does a two stroke outboard give any indication that it has too much total timing? Aside from total failure or melt down. If so what side effects may you notice other than the worst case senario? Can an audiable noise be heard like the ping you here from a 4 stroke automotive application with too...

    Prop Slip

    I have a Evinrude 150XP on a DC 175 Larson. It's mounted on the Third hole from the top, on the transom. I am running a 13 1/2" X 23 Pitch Renegade prop. The boat runs at 5500 rpm and 51 mph via the speedometer. By my calculations this looks like about 20% slip. Is this acceptable or are there...
