Re: Neel's Palm Beach 22 build

Neel

You can do it! This is certainly not first time build! My approach would be to cut fat, then use my belt sander to cut off the stuff that is not boat.

Re: Biscayne 22 vs Belle Isle

Pat I don't see much difference in the running surface. The Belle seems to have a little more round transom, barrel. The Biscayne has a little blockier transom. That might but you an 1" or 2" width in the rear cockpit. No handling or performance difference. Just a matter of taste. On both ...

Re: Gear ratio....i'm so lost

Joe

If your engine will turn 4800, I assume it's not diesel. At 10 knots, that's about 65% of WOT. That is about right for gasoline. Diesels at 80-85%. The prop estimates should be good as starting point. Cruise RPM should bee about 2875.

Re: Gear ratio....i'm so lost

Joe

With a 2:1 ratio and 4600 RPM, I'm seeing a 16x11 prop. 16x10 at maybe 4800 and 16x12 at maybe 4400.

Let me try a different approach. What RPM is the max Torque and continuous operating RPM? That should be near the cruising speed. Boats are really about torque not ultimate HP.

Re: Gear ratio....i'm so lost

What Ken said. Plus, depending the exposed shaft length you may want to consider a whip strut.

Re: Glen-L Party Boat

Actually, I would love to build this boat, now. But, time and sensitivity to epoxy don't make it possible. I need to finish and run what I have!

Check with the prop-shops on the shaft dia. 1 1/8 may be plenty. 3000 RPM gives a blade tip speed near 200 MPH. After that you can get blade tip cavitation on a 16" prop.

Re: Gear ratio....i'm so lost

Joe I'm no expert on these hulls, for sure. I don't know about HP on these boats. But, you will be looking for a shaft RPM of 3000 w/16" prop. That gets you to a 1.5:1 gear. A 16" prop you will probably need a 1 1/4" shaft, maybe 1 1/8". I think a starting point on the prop would...

This transom doesn't look that heavy to me, lots of parts. I don't know the Gentry build up. Here is a picture of the Tahoe 19 build up. Both, top and bottom have that heavy laminated build up. That makes transom drains impractical.

Re: Monaco Restart

You might check with Hundley Chris Craft. They have tons of old parts. You might have to do some work to clean the stuff up. They are in Lake Houston TX.

I've wondered about this, too. I'm not happy about my exterior one and didn't think I wanted a thru-hull.
