clearing exhaust tube w/ rev footholds

[fst89lx]

I was working on my ski tonight, trying to get the rev footholds in and noticed that the exhaust tube hits the toe on the right side. In order to remedy this problem, I just dented the tube w/ a hammer until the foothold would fit. Will this have any adverse effects on how the ski runs??


Yes I did search about this and found out that the preferred method seems to be to notch the foothold but It's a little too late for that now

Thanks!

How much did you dent it? If it is less than half way it shouldn't have hurt anything, but I would have notched the hold. You should be fine.

I'll take a pic of the tube in a bit after I eat dinner.

Here are the pictures. If I have dented the tube too much then I guess I'll just have to get a new section of tube welded in, but if the engine will not be effected by this, then it is staying.

Anyone?

Also, I plan to drop in a 701 next year to replace my 650. If the dent is ok to run w/ a 650 now, would it be ok for the 701?

ouch! that is going to restrict exhaust flow.
How much is another question . . . . every bit will affect backpressure
amount of water in the wbox, performance, etc.
I would look for another one- someone online has ditched theirs for front exhaust and dual scuppers so maybe get one cheap.

the shiddy part is it might be fine,, but if its not you gotta tare your ski all apart... Again..

people do run a 2" exit,, i think it will be fine

I took my exhaust tube to a muffler shop, had them bend it to fit. i then cut the original flange off and replace it with a garbage disposal drain with a 2 inch to 3 inch rubber coupler. Its all in my build page here....http://x-h2o.com/showthread.php?t=31058

im In the process of putting revs in my sj, i ended up pulling the pipe out and dropping it 1.5 inches. i just bored out the foam and lowered the pipe that way. Im thinking about starting a build thread because i have never seen anyone do it my way.

Actually most people do it that way.

i am about to put revs in my sj. why not just mod the hold a little bit?

All the threads I could find they would cut all of the foam out and refoam the entire tray area.

Do you have any pictures? If you lower it at the bulkhead then the flange won't sit flat on the rear of the hull. Or did you lower it at the front and the back.

I seen someone that took it to a muffler shop and had a bend put in it to clear.

you guys realize that the revs weren't designed to fit in a SJ right? there is a lot of work involved in making them fit correctly.

I just lowered it in the front and twisted it clockwise about half an inch and it lined up pretty good...

bluegtate just installed another set of REVs and he just cut the front of the right hold, put some wax paper over the tube, and glassed over it... came out nice.

I lowered my exhaust tube and still ended up having to cut a notch in the footholds. to make flange fit flush I built up the transom using marinetex
waste of time
just cut the foothold and rebuild while reinforcing the whole tray with biax:biggthumpup:

 

[fst89lx]

Looks like I'm going to either get a new tube or get a new section welded into this one and mod the foothold.

 

[Kennay]

All you have to do is lower the tube, and then take a hammer to the flange to make it flush against the boat, or if you didn't lower it alot like I had to for my setup, you can twist it for a new flush fit ... super easy.

better footholds is a better idea.
