Tank Vs. Muffs

[Evinrookie]

I have a 1967 Evinrude 80 Hp and was told that the standard suction cup style muffs won't work on my engine. The guy I had rebuild my starter showed me some antique piece of twisted metal with a hose fitting that he uses for older engines.

As of right now, the only option I have is to remove the hydrofoil the previous owner put on and run it in the hugely oversized trashcan my city makes me use. It would probably take me a good 20 minutes to fill it to the level I need and then I've a huge heavy bin full of water to dump (and nowhere to put my trash).

I know a test tank is the preferred method for working on an engine because it puts a load on it and makes it less likely to run away. However, I would prefer to something a little faster and easier to deal with.

I don't want to haul down to the lake and find a starting problem that I need to fix on the ramp. I also doubt the fish or the EPA would appreciate me decarbing my engine out on the lake. Does anyone know if the muffs will or will not work on my engine or what alternatives there might be?

Muffs won't work. There was a flushing attachment made by Tempo in bygone years, but they are about as rare as chicken fangs nowadays. It clamped to the cavitation plate and fed water into the screen in the snout behind the prop. I still have mine.

If that motor is like my '58 Fat-Fifty, you may be able to adapt a standard seet of flush muffs to work. See if you have a grating on the side of the lower unit, just below the A-V plate. If so, remove one of the muffs rubber cups and slide it on the LU 'till it covers the grating. I used to remove the grating to le is suck more water. If it fits relatively tight, you need to put some tape on the grating above and behind the prop. Now turn the water on pretty high and start it up. Watch for water discharge.

Just above the cavitation plate is a inlet plate. Take this out, and make a copy from sheet metal, and solder on a female hose connection. All you need here is a pair of tin snips.

Thanks for the suggestions guys. And thank you FR for the heads up on the Tempo brand. I just picked one up on eBay for $16 plus shipping (Part# 916 TFC). The company selling them has a bunch of different types that fit different engines. Search "Tempo Motor Flusher" on eBay and check out what they have. I'm sure there are alot of people on this forum that need these. You guys are lifesavers.
Thank you.

You can make one like I discribed in about 15 minutes for probably 50 cent's, depending on what you have laying around in the way of material. Plus! it won't fall off while your not looking.
