cavitatin plate

[1436delta]

WELL WAS LOOKING AT THE BOAT THIS MORNING BEFORE WORK AND I NOTICE THAT MY CAVITATION PLATE WAS ABOUT TWO INCHES LOW FROM THE BOTTOM OF THE BOAT IS THAT TO LOW ? I HERD THAT IT SHOULD BE EVEN WITH THE BOTTOM FOR MAX PERFORMANCE IF SO I HAVE TWO BOLT HOLES TO MOUNT IT WITH THAT ARE LOWER ON THE BRACKET WILL THAT HOLD IT WITH OUT THE CLAMPS BECAUSE THAT WILL MAKE THEM TO HIGH? OH I HAVE A 92 EVINRUDE 15 HP SHORT SHAFT

Your cavitation plate should be even or slightly higher 1/4" with the bottom. You should see a noticeable performance increase.

I personally wouldn't trust two bolts. You can build up the transome or get a set back plate. Set back plates can be found at any jackplate manufacturer. They are not hard to build yourself https://www.tinboats.net/forum/viewtopic.php?f=13&t=10425

My cavitation plate was about 2" lower than the bottom of the hull which was fine last year. This year the river I'm on is quite a bit lower. I added a minijacker set so the cavitation plate is about 1" above the bottom of the hull. I have also tried running with a 1" thick spacer on top of the minijacker. The water pickups are well in the water and the motor has a very good stream of water from the pee hole.

I got my Minijack plate from E-Bay $42.00 with shipping.

I think you will love it. It will change the way your boat handles. You can also raise it a little higher than even with your boat. As long as you have good water preasure cooling your motor. I believe that they say you can raise your motor a 1/4" for every inch of set back. I have a 5 1/2" set back and my motor is 1 3/4" higher than the bottom of my boat. It still could go up another inch +.

If it's any consolation, it looks good. I can laugh with you because as you know I did the same. I was lucky and had free material. I probably should have bought one also, but I'm a do it yourself kind of guy and like a challenge.
