View Full Version : Are these mufflers beyond repair?

04-05-2013, 09:35 AM

Obviously if I can avoid spending $500 on replacements I will. I just feel at this point building glass may be a temporary solution at best. I would love to have a more solid foundation to start with. Has anyone glassed a metal or plastic fitting on to one of these mufflers? The PO must have started to have a leak and decided that hulking down on the hose clamps was the solution. They dont have to be pretty, I just want them to work and not leak like a sieve. I have looked thorough archives and seen plenty of references to repair, but not actually found photos of what has been repaired. Thanks guys!

They look to be made out of fiberglass, so they can be repaired. Grind off the broken/crushed parts. Put a taper on all of the edges that need to be repaired. Insert some sort of round disposable piece that can be used to get the round shape right (Ive used a solo cup wrapped in wax paper) and then put several layers of glass over it.

That is simply brilliant! Thanks! I will use that method!

I used you idea, i just couldn't get the dixie cup to stay put so I made a mould using the cup and foil, i will wait for it to harden, remove the mould and then glass a few more layers and my formed piece to the muffler.

They must have changed a lot of stuff on this boat after the first year. Mine and others I have seen has the one piece Silent Master Egg-sawst. I had to do some glass patch work on mine too as it was leaking...

If you're replace'n all of your hoses, I used trident. Trident was the only one I could find with a blue stripe down the center. It don't say mastercraft like the OEM but I loked all over fer that...

I saw that your model had the other exhaust. It would have been nice because my tubes rub the corner of the motor mount bracket. I am going to grind a nice smooth corner so that doesn't happen again. Mine is the only one i can find that has 2 chairs in the cabin as opposed to one and a sink. The 90 is an odd ball boat for sure.

Mine has two chairs too and a toilet. My wife said that we would never use it but it gets used.... I clean it out at the end of every season and put clean blue wader in it. It don't get used that much but it gets used. lol

I think this one used to have a toilet, I may or may not get one to put back in it. I am surprised it doesn't smell like death being used at all and not cleaned out every weekend. That does make it more tempting to snag one. Is your toilet original to the boat or did you get one aftermarket?

They are OEM brother. Look at my pics in my profile and you may see a hint of it. It goes right in the fore peak. The bed has a little square pad in the front with a piece of carpet that hangs down in the front to hide it.

The Blue water is in the bottom and is separated. Now when you dump it, now that stinks! lol
