72 27' seacraft

I just came back from looking at Capeds boat, his hull is the same as mine, actually it confirmed that my rear transom was cut flat to make it an inboard (Rather than make a pocket). The bottom rear of my hull has about an 18-20" flat, as opposed to the 4" flat where the "V" usually comes together. My mechanic is worried about the I/O installation and having good water coming back without the
"V". Anyone have an opinion, I figured if anyone knew the answer, you guy's might. I have a choice to "V" it off, install the jackshaft I/O the way it is, or keep it an inboard. From an engineering standpoint, I don't think it will make a difference having a larger than normal flat, maybe I will lose a little speed, but I am not sure. I want to make it an I/O for trailer-ability, better fuel economy, manueverability and better cruising speed.

Thanks

In my experience, the wider the "pad" - the faster/higher the boat will run. The pad will make the boat more stable at speed. If anything, I believe that the pad will give "cleaner" water for the prop to spin in. I wish my 25' Seafari had some kind of pad on it- might keep it from listing. Maybe this winter....Again, just my experience & opinion-

I agree with Doug, most go-fasts these days have some kind of pad on the aft bottom of the "V". Apparently this will help the boat plane better, be faster out of the hole and should work great with the jackshaft.

Thanks for the input, I agree with you and Doug, I may go for it. The transon was checked today, We were sure we wold have to re-do it, but it is very solid, a little damp, but not rotted. It is 2.75" thick, it will have to be trimmed down on the inside to 2.25". The glass on the outside of the lower transom is 1/2" thick !!! It is amazing how much glass was used on that hull, no wonder it is so heavy. Theoritcally it may pound if I launch it hard, but I have only been able to do that once in 3 years, and the landing was not that bad.

Thanks,

Dan

Seacraft POUND? You are a funny guy. You should enter that comic show on TV.

I say go for it. That 27cc with that pilot house is a cool boat. Be shure to take pics of the install and post em. Good luck.
