I'm running a 76 Johnson 35hp and an 80 Evinrude 35 hp and I need to know the right level to have the prop on my hydro to keep the water flow uninterrupted. Does it differ from the usual cavitation plate level with the bottom of the boat? I tried that and I believe I was losing flow on tight turns under deceleration to the tune of an overheated Evinrude. Both these engines are 22" from the clamps to the cavitation plate and I made the transom 22" to accommodate them specifically. Boat is 11' long and 76" wide at the transom. It has very little bow rise and draft when on plane. Should I go deeper with the motor or add a low point pickup like on a tunnel hull racer? Maybe add some weight in the back or a 50hp Mercury at 60lbs heavier? Please help before I'm buying head gaskets in bulk. Thanks.
