1971 Ski-Doo Olympic

Tomorrow I am going to look at, and most likely pick up a 1971 Ski-Doo Olympic, at least that's what I was told it is. I'm planning on completely restoring it. I'll get some pictures up tomorrow, but he said that the engine "feels alright." From the pictures it looks like it is in decent shape. The hood has a few cracks. Is that a fiberglass hood that I could easily repair? Also the clutch has some rust on it, will that be a big issue, or will I be able to take care of that somehow? Thanks for the help!

Yes, fiberglass hood and the rusty clutch is not a problem.
You can clean it up with 120 grit sandpaper.

You can get some tiger hair fiberglass treatment and liquid hardener to seal the cracks on the cowl, worked great for mine. It was about $25 at autozone.

If it's a 1971, it's not a fiberglass hood. It's polycarbonate, a solid, color through plastic. It can be repaired, but it takes the correct glue. The cracks will also travel if you don't address them correctly.

You drill a hole at the end of the crack to stop it from spreading first. And fiberglass will still work as an adhesive regardless of the material it's being applied to.

Yes, it can be painted as long as you use the right paint formulation.
You need to be sure that the paint is flexible enough to not crack and peel right off.

Yep. Make sure you do exactly what the directions say (i.e sand using 40-80 grit and remove wax, paint, etc. prior to application). It won't harden like it should in cold weather, it's suggested that you do it in a 75 degree environment, but if you can't then just let it set longer.

Okay, thanks for the help. I'm going to get it running again before I do anything cosmetic. I was told the starter recoil is frozen, and it won't catch to start the engine, so that's the first thing to figure out I guess.

If the starter pawl is installed backwards it will do that.

I found a hood and wind shield for $20, so i'm just going to buy that most likely. That will be cheaper in the long run anyways. Now i just have to fix the starter. There are a few holes in the can, but that's getting welded.

Does anyone know whether or not the exhaust/muffler off of a 335 will work on this, even though it's 399? Thanks
