re: Your add-on question in the other thread.<br /><br />You don't have cavitation, it is probably ventilation, but could be a spun prop hub.<br /><br />If your Whaler 13 Sport is a blue liner, pre-'73 model, it needs a short shaft (15") engine.<br /><br />Later 13s had a 20" transom and need a 20" (long) shaft engine.<br /><br />Where is the anti-ventilation plate relative to the bottom? It should be even to 1" above the keel.<br /><br />Give us more info, please.
