Opinions on motor change?

[Chalk]

Hey, what about me. I got a phone, you could have called. I'm good for the $17 till the next time I see you.

You are, but they only had one for a 7-12 wt

Do you have a hydrofoil on your moter? I would not be without one on a smaller moter.

There is an article in Fla Sportsman about it. I don't think you will get enough difference to justify the cost. If you have money to burn change boats.

Are you talking about the difference in the 40hp4s verses the 50hp2s?

I think Chalks right on about the mysteriousness of tunnel hulls. I've never got mine quite right and am still tinkering around with ideas of 4-blade props and even doing a little fiberglass work to extend the tunnel a little closer to the motor. I saw a picture of the new Sterling and the motor sits up in a pocket with the tunnel extending closer to the prop.

I'm having issues with the prop washing out at full throttle, like the water is too dirty. I think the tunnel makes the boat squat a little and makes the hole shot suffer but once you get up and running the beauty of the tunnel takes over and you can run in spit.

Theres also some websites from Texas and Louisiana that have more info on tunnel hulls. Those boys over there seem to love tunnel hulls. Heres a link to a company that makes a cavitation plate that may help, its designed to channel water around the prop after coming through a tunnel as opposed to the other plates such as a Bobs which I am running.

That plate looks a lot like Bobs hydroplate. Can you give some links for those sites from Texas and Louisianna?

RedBelly,

I'll have to look them up, I found them linked in a thread on Florida Sportsman.

Heres a link to a thread in Florida Sportsman that talks about tunnel hulls. It also has a link to a thread of a guy that built a tunnel hull in Tx and it shows pics of the kind of plate I'm talking about. I just have a Bob's and it helped a lot with the cavitation but I'm considering a shallow blaster below:

These are all forums that talk about cavitation on tunnel hulls and the compression plates.

Here's some pics you can see they're a little larger than the Bob's plate. The side fins are supposed to compress the dirty water coming out of the tunnel which is what causes the prop to slip.





There thats all the info I've got up to this point, hope its useful.

Thanks T Smith, that plate is shore a biggun! I'll read up on this stuff, as I'll have the tachometer on in a day or so, and then gittin a 4 blade prop.
