cavitation plate is just below water when planeing

[ Edited ]

I noticed today that at plane. The cavitation plate has water running over it.

I thaought that at plane i should see the cavitatin plate completely.

stock prop.

Re: cavitation plate is just below water when planeing

Your motor is probably mounted too low. See your dealer about raising it up one or two holes or whatever it takes to be visible.

Your rpm is too low, get the next smaller pitched prop. That should help your hesitation to go away and make your motor run more efficiently. It should be about 5600 rpm with a max of 5850.

Excellent thanks. Hopefully  my dealer will do this for me. I just boaught the boat, only has 14hrs on it.

What will this do too my performance, hole shot and top end.

I know i've heard other people talk about the slight hesitation on theres too. Will it completely go away or is it normal for it too do this to some degree....

If i run the motor like this for a while will it be ok. I'm in florida and boat won\t be back home for 3 months now.

thanks mike

Get the engine mounting height correct, the engine checked over, and change the prop to obtain the 5600 rpm and you may find that the hesitation is minimized or completely gone.
