Jack plate? - 15 hp on 12' Deep V. Is it worth it?

[aeviaanah]

I want to get a few more opinions on the subject before I choose to or not to build this jack plate. My boat is actually a mod-v.

Do you think a jack plate will help a 12' mod v with a 15 hp 4 stroke?

Please don't consider cost or time.

Maybe I missed it and/or its in another thread. Did your motor arrive, mount it, measure where cav plate is, and have any performance numbers?

Cav plate way lower than bottom: worth doing, noticable improvement.

Cav plate near level with bottom: slight improvement.

Cav plate 1-2" above bottom: probably not worth building.

PS: Also better to check visually while on plane, vs measurement.

Hey this is the post I was needing to see. Thanks man. Ill wait the motor should be here this week. Ill mount it and measure cav plate. I dont have any measuring devices for performance. I downloaded a speedometer on my iphone. This should help a bit.
