Aphrodite 34 (Built at Rex Marine in Sweden) strut repair

Recommended Posts

The propeller strut on my 1984 Aphrodite 34 is moving up and down.  

Attached is a picture of the strut from outside the hull, and also inside the hull right above the strut. I am thinking that there are bolts holding the strut in place - maybe hidden under the fiberglass in the protrusion inside the hull. I could grind the cap off and see if I can access and tighten the bolts.

Or, I may just have to grind away the fiberglass around the outside of the strut and see what is there, but before I start that I thought I would see if anyone had better suggestions.

Thanks.

If the bolts spinnwhen you try to tighten them, THERE ARE NO CRACKS, and leaking is not a problem, you might be able to grab the tops of the bolts with vice grips and tighten the nuts.

 

otherwise... it will only take an hour or two to dig out the filler on the outside and you may as well just do it. You will be done in a day and it will be right.

Bake, The strut might be bolted but I doubt it. It is more likely a blade cast right into the hull. If you grind (or cut) away the inner glass the strut may drop right out.

This is not a repair you should put off as if the glass inside breaks free, well lets just say you better hope your bilge pump works.

I did this repair on my boat. My strut was loose and leaked when I bought the boat. Now it is rock solid

1) remove all grass to the hull shape

2) I made a 5" block out of marine plywood

3) cut out the shape of the strut

4) bolt and bond the block to the hull

In my case I made 2 angle brackets to hold the strut in place once I realigned the prop shaft.

5) once the shaft and strut where aligned, fill the cavity with epoxy

6) I then glassed the whole thing in.
