Morgan Moorings 50 shaft strut bend

Hello,
I managed to get the shaft strut of my Morgan Moorings bend after I ran on the rocks when my engine failed......
I was trying to remove the strut to bend it back. I saw some articles where struts go through the hull and have nuts to remove it.
However in my case the fuel tank is where the nuts are supposed to be in that case.
Is it possible that the nuts or however it is attached are on the outside (under the fiber glass)? I don't want to start removing fiber if I'm not sure.
Or would it be possible to bend it back while in place?

Re: Morgan Moorings 50 shaft strut bend

You may be able to bend the strut back in place, but it needs to line up EXACTLY with a straight propeller shaft, which is not what you have, either. You should be able to use the new, straight shaft to show you how much the strut needs to move, and bend it into the right position with repeated trial fittings. It may take a long while, so you will want to do it yourself or not pay by the hour. Using a sledgehammer might create shocks that would dislodge the base of the strut from the fiberglass. Some sort of hydraulic or screw jack might be better. Good luck.

Re: Morgan Moorings 50 shaft strut bend

I'd try bending it first too, though I'd use neither a hammer nor a jack.

If you can get hold of a big pipe wrench, 36" or better, and some aluminum sheet, 1/8" or better to protect the strut, tighten the jaws as tight as you can about where shown in the picture below, and get a 10 foot or so cheaterpipe and lever up. Or down from the other side.

You start closer to the route to avoid putting an unremovable kink in the middle of the strut, which is possible to do if you were to start lower down where you have better leverage.

As you work the bend out, move the tool gradually down the strut.

The keel needs to be resting on the ground.

If you see some motion, you can consider continuing with the pipe wrench, or you can go to the scrap yard and get some 3/4" -1" steel plate and cut and grind something to a better fit and use that. Or the yard might have a tool ready made.

That shaft looks hard up to the shaft log; it may not come out without 'relieving' that contact first, I'd go for it with the shaft in place, and then deal with the shaft after you're able to get it out.

That looks like a pretty long shaft, there's a slight chance that it's not even bent, or only slightly bent and able to be straightened, if money is an issue.

Re: Morgan Moorings 50 shaft strut bend

Thanks for the replies guys. Really appreciated.
I tried some metal plates with threaded rods and slowly turning the nuts, but all that was bent was the metal plates.
I found this video:

where a car jack was used and i tried it this afternoon and the strut was bent to the middle. See photo as well.
However the shaft is still not running fully free. I can hardly turn it with 2 hands.
The cutless bearing was replace 1 year ago and the engine ran less than 6 hours after that. It doesn't appear that the bearing is worn out on on end.
Any further suggestions?

Re: Morgan Moorings 50 shaft strut bend

I'd guess either the shaft is bent, the bracket is twisted or both.

You're gonna have to pull the shaft to tell. Once you get the shaft out you can have it checked for straightness, and use a line as shown in the video to check for alignment and twist in the bracket.

I'm assuming "strut was bent to the middle" means you straightened it successfully?

Re: Morgan Moorings 50 shaft strut bend

Use jacks or hydraulics. No sledgehammer. There is risk of damage to the hull.

If you can’t straighten it you may have to remove the tank

Re: Morgan Moorings 50 shaft strut bend

That strut is supposed to be angled somewhat- not sure if yours has gone a bit too far but it is angled very slightly to allow the shaft to make it past the rudder I believe... mine is the same way.

Excellent point. Mine is too but the strut itself is straight and mounted off-set.

Re: Morgan Moorings 50 shaft strut bend

Is the strut twisted relative to it's forward/back alignment as well? Meaning not lining up with the centerline of the boat?

Re: Morgan Moorings 50 shaft strut bend

M50 RELAX also has the strut off center, this was done to allow shaft removal without dropping the rudder.But bent from hitting a rock or flotsam is another matter
