Opposed,
When I set up my motor I run my cav plate even with the bottom of the transom or even a tiny bit higher. Use a straight edge along the center keel & set the cav height even with that. Be sure to have the cav plate running on the same plane as your boat bottom too. It must cut thru the water at the same angle as the boat for starters. Remember if you set the motor out just one pin it changes the plate angle too so height must be reset to run true.
I just am even with the water with my cav plate running wot. Remember too when the water passes under & out the rear it instantly raises level before
getting to the leg of the motor. This gives another 1.5" or so of level of water at wot. Also be so careful how high the clamps are running on the inside of the transom & be sure to chain the motor to the boat too. My 12 tinny with a 63 Merc 200 runs very well using this formula & runs full rpm with stock 3 blade prop that is aluminim. Wish I had a Stainless Steel same to run. I’m only 02 hp different except I hide the 22hp under the 200 cover.
Hope this helps.
