My 1st tunnel hull questions

[set_the_hook]

Well I got the old girl running, Thanks for all the help.
We out her in Lake Houston this afternoon and like I said this is my 1st Tunnel Hull.
1993 19' Predator with a 120hp Evinrude
This motor has a 4 bladed prop. Seems hard to get on plane, I thought that with the Tunnel it would jump on top; wide open it runs 5500 rpm-- speed ? no speedo.

Hard to turn, when you take a sharp turn it cavitates

The motor does not seem to be in the water far enough when on plane the top plate, right above the trim tab is barely under water
water pressure look good, but I do not have a gauge on it. Tell Tale is strong.

I hope that some one out there has a boat like this and tells me that all this is normal.
If not do I need a jack plate?

After all the work that I have done on this motor and boat I do not want to tear it up

Thanks Mike

Re: My 1st tunnel hull questions

It is the same sats as the 19' Bluewave tunnel I can not find any info on the Predator bay boat line, but I was told that one of builders for Bluewave left and started Predator. I am not sure if this is true, but they do look the same
I will get some pictures up tomorrow

I thought that a 4 bladed prop would have a GREAT hole shot and slow down the top end too. It just runs different than the other bay boat that I had. I love her all the same, Best of all the kids like her too.
