Mirage 33 strut

I'm looking for some information on the design and or removal of a strut for a Mirage 33/35 or Mirage 30. There might be other models with the same design but I know those are all the same. Thanks for any help.

Re: Mirage 33 strut

I might be able to help if you can provide more information. I have a copy of the design drawings for the Mirage 35.

Re: Mirage 33 strut

The strut on my mirage 33 has a slight amount of play in it. I don't have vibration issues but I would like to find a way to tighten it up. It has on the inside of the hull a fiberglass dome with 2 bolts holding the strut, but with those bolts removed it doesn't want to come out. I sanded the area around the strut but appears only to be fiberglass around it. So its not the typical design I'm familiar with, being a metal plate on the bottom of the hull with 4 or more mounting screws. So if I knew what it looked like removed or some advice on how to remove it would be a big help. Its getting late so I plan to launch these season and tackle it when it comes out this fall. Right now working on getting some information on it so I will be ready.

Re: Mirage 33 strut

We're talking the prop shaft strut, right? Mine is shown in the attached photo, looks what you're describing as a typical installation. It sounds like yours may have been modified. I'd be happy to dig through the drawings and see what the original design looked like if it would help.

Re: Mirage 33 strut

Yes the prop strut sorry should have made that clear. Its definitely a factory install I have seen a picture of the same dome on another mirage. I would appreciate the help. Its a great boat but finding info on it can be a bit difficult.

Re: Mirage 33 strut

Hmmm, now you have me curious - clearly not the same construction as what we have. FWIW ours is a 1989 model, which I understand was the last year they were built.

In any case, I'll take a look and will post back here if I see anything interesting. Enjoy your Mirage - we're enjoying ours.

Re: Mirage 33 strut

Thanks, mine is a 1982 model year. They are great boats especially here in the states where they aren't well know and can be bought for the price of a hunter. I had read a post from 2013 that talked about a Mirage 30 with the same design and same problem but never posted what he found with his.

Re: Mirage 33 strut

Used to have a Mirage but it had an outboard, generally well made boats.

From what I can tell from your pictures it looks like you have delamination at the strut, possibly because the strut style does not seem to have enough support ie. a proper flange.

I would look at cutting it out repairing the glass and then installing a more typical style strut as shown by Anglais-in-Hull.

Not fun but not really that big of a job.

Good Luck

Re: Mirage 33 strut

Definitely a good idea to replace it with a more common style. I will have to take a picture of the area after I sanded it. The picture you see there is after I scraped away the loose sealant the a putty knife. The area around it is solid checked with a mallet and moisture meter.

Re: Mirage 33 strut

FWIW here’s the view from inside my hull - looks like they changed the design by the time mine was built.

Re: Mirage 33 strut

What inboard motor did your boat come with from the factory?

Sorry, can't help you with that one - it had been re-powered before I bought it and I don't know the history.
