Hah! Imagine being called "experienced"! Just a backyard hacker flubbing around. I figured it's either throw the boat out or try this, and this has, if nothing else, been a great conversation starter! I was worried about the planks/stringers popping right off, but I had it down to bare woo...

Jacking out a hogged hull!

Thanks to everyone for their tips on what's wrong with the hull of my 1961 Thompson Offshore, in a thread back in September. It was hogged, and several folks suggested ideas on how to correct it: brace it against the shop ceiling, while keeping it wet, for several months. Unfortunately I don't have ...

So to measure the transom, I go from the transom top, vertically downwards to a straightedge held at the bottom of the KEEL? I was going to the bottom of the hull. This would make the motor about 2 1/2" too high. Thanks again for all the help!

Thanks again John: I didn't know transom height is measured at the vertical. The face of the transom is actually just under 22". I'm guessing it's not original, since I can find no serial number anywhere in it. When it was on the trailer, the motor trimmed to vertical and a straightedge is held...

John, that's a pretty impressive makeover! Beyond what I'm capable of doing, I'm afraid. What kind of boat is it? Stiffening the stringers might be all that is required. I put on my mask and snorkel and dove under the boat yesterday, and the keel looks straight. The trailer does not have rollers, bu...

Hooked bottom on 1961 Off Shore 19 -- how to fix?

I'm writing this as a result of answers I got on a previous post in the Engines forum about motor shaft length. Turns out the problem is a hooked or hogged bottom. Some people have suggested jacking the keel down, against a strong I-beam or something. This will likely straighten the keel, but I'm su...

Hi everyone-- I have cross-posted this thread to the Woodenboat.com forum, and opinions there are also that a hook or hog on the bottom is the problem. Joe, I'm aware of the effect of trimming in, but as soon as I trim it out, the prop cavitates-- which is one reason I thought shaft length is the pr...

Very interesting you'd mention a hook in the bottom. Part of getting it back in the water was a new coat of bottom paint. When I lifted it off the trailer there's a distinct, though shallow, depression just before the transom-- perhaps only 1/8" if a ruler were held against it. I believe it was...

Correct outboard shaft length for 1961 Off Shore?

Hi-- I've recently got our old family Thomson Off Shore 19 back in the water after 6 years on a trailer. It's 18'8" and is powered by a 1990, 100 HP Mercury. I've had it up and running a few times, and once on a plane the handling is, in a nutshell, scary! It bowsteers, the stern slides during ...
