Muff placement help

[inthedirtagain]

Before I royally screw something up, can ya help a brutha out with the placement of muffs on this 66 Evinrude? I've been filling up a garbage can, but it would be so much faster and easier if I could just put muffs on this ol' gal. I'm new at all this boat stuff, so I appreciate the help. Is this the location, and would I need to trim the cup because of the proximity to the cav plate?




Also, I know that the plate above that is accessing the exhaust, but for what purpose? Thanks for the help?

As far as I know, you can't do it on that vintage....at least in any practical way.

Others will weigh in and confirm, or deny...

As Tim said, you can't use muffs on that engine. They used to make a contraption that you could attach to the water intake on the rear of the cavation plate and run them on a hose, but I haven't seen one of those in 15-20 years, I haven't seen any advertised either. Maybe someone will chime in if they know where you can get one.

So what would be the purpose of that plate then? The last time I was out, I had a buddy run the boat WOT while I checked the depth of the cav plate (2-3in below surface), and I noticed that water was coming out of that cover as if it weren't sealing 100%. When I pulled the cover today, I noticed that the gasket was torn. I think I remember reading somewhere about a contraption on the intake for a hose, but perhaps this cover can be pulled when running in a can to ensure that the pump is working? Hell, I'm grasping at straws at this point, so any information is mucho appreciated.

That is a cover for the exhaust housing, replace the gasket and see if it seals up if it bothers you. Your best bet is to run it in a barrel of some sort, making sure the water level is well above the pump.

Thanks for the advice. I'll just continue with a bucket for now. Don't want to kill it.

Tempo used to make a flusher for your mtr but I heard they went out of business. Stick with the barrel or the lake.
