transom flex

[cooppat]

I am looking at a 1974 20'sf, that has a 1988 175hp black max on it, the transom currently has an alumnium plate which appears to be well done, it has not been raised and the transom has not been restored.

Should there be some flex in the transom, and how much is acceptable, what should I be looking for as a clear sign that the transom is junk.

I realize I would need to replace it at some point but when should it be done?

No Flex, Look for bleeding at the transom cap and/or engine bolts [img]/images/graemlins/shocked.gif[/img]

Bottom Line---> Metal Plate + 31 years = JUNK

What is a good way to test for flex in the transom, The surveyor sat on the engine and moved around and observed the flex in the transom, does this sound like an acceptable method. I question the method used, I have not seen the boat personally.

thanks for the information

The surveyor did the right test. Unless you drill into the transom a rubber mallet listening for hollow areas is another method.

BLEEDING @ 27 years



"JUNK"

I agree with that. The only sure way is to drill some hole and look at the wood that comes out. I'd be willing to wager it's mush...

Mine had hundreds of big black ants in it, and it was still stiff. Made Chucks look new.

consider it shot.....especially if it's had multiple motors.

Listen, if you want to find out all we know about these boats, spend a little, or a lot of time searching around this site and I am sure you'll find what you need to know.

here is a picture I hope it works.

Thanks again for the information, I have been searching this site for the past several weeks, the information is great and very helpful. My wife things I have some serious issues with the amount of time I have been reading on this site. You guys are great and provide a great resource.

For me my thinking is “When in doubt cut is out”. But on at 1972 with a aluminum plate that was added because of a known problem with the transom giving added stiffness to by a little time there isn’t any doubt “CUT IT OUT”.
