Optimum motor height per BRP is when the AV plate is above green water when you're up on plane and fully trimmed out. Picture below shows the AV plate on my 25" motor at 3.5" above keel BEFORE I had Don Herman redrill the motor mount holes on the bracket to raise it about another inch! And it's STILL too low! Needs to come up another inch for top of AV plate to be above green water, so that would put me somewhere around 5-5.5"! I have to admit that I only picked up about 50 rpm and 0.5 mph with the last raise so another inch might not make much difference, but I'm sort of a perfectionist when it comes to engine performance, so it kinda bugs me if there is any more splash and drag than necessary!

Bushwhacker your exactly right... with the Setback I have used 3.5" on a 30 Inch Bracket... Since i have not launched my Tsunami Yet... Just picked up the Engine Tonight for it... My Bracket is mounted at 28" then i see these Seacrafts like another 1.5 to 2.5 inches to run... Then the AV plate can be raised even more... Basically until it Blows out then down One Hole... with that being said...

I just got my hands on a Land and Sea Electric 4" Jackplate to place onto my Bracket...then the motor. I am going to just set it up in the 2nd from the bottom hole basically up 2" then i will have the The opportunity to run it up another 6 inches once on plane. Drilling and Installing Water Pressure gauge as we speak...

Really Appreciate the input... Want to just get this close the first time.
