Flush muffs

[lockieboi]

Can anyone recommend a set of flush muffs for a 15hp Johnson 2 stroke OB.

I have these at the moment

But they don't work for some reason.

They are single sided muffs so do I need double ones maybe?

Thanks

They'll work, they work on my 115hp - make sure they are tight when you start the engine and they're in the right position.

As said they will work !, just keep those muffs tight - I use them on my 50 , 30 & 25 ....same as the link.

I squash my muffs every so often to keep them tight.....

( Sorry its been a long day ...... I'll get my coat...)

Thanks.

I shall have another go.

I did notice a lot of water escaping from the cups so maybe they were not tight enough.

Cable tie the arms together to add tension.

Good thinking

Short of the wheel, cable ties are the greatest invention ever! Used thousands of the things over the years for repairs or fixtures to just about everything.

but what is better cable ties or duct tape!

Another option is a garbage can. Much quieter if you have neighbors. Also better for tuning since you can hear the motor better.

With that said I use a similar but much older set of muffs. Actually I have two pairs. Leakage is normal. Just make sure the motor is peeing enough.

Thanks Peter.

I use a dustbin (uk version of garbage can) at the moment but I want to put my doel fins back on so with them on it won't fit.

I reckon the best thing to do is, when you have finished flushing the engine take it out of the dustbin and put the doel fins in the dustbin. It's the best place for them.

I'll second that too , the amount of people that i see setting the engine up on muffs then drop the boat in the water to only have problems
At least with a tub of water it gives a bit of back pressure on the exhaust if setting up the tickover,

Once blew the bottom out of a plastic dustbin/garbage can when trying to start an engine after flooding the carb ,,, fuel must have gone down into the exhaust when it back fired the explosion shot the engine about 3 ft high and blew the side and bottom out of the drum ,, engine ran great after that but we all had wet feet lol

Haha,

I only want to put the fins back on as I noticed at the weekend it took a long time to plane 3 up.

Was hoping the fins would make a difference.

I would only be using muffs for flushing not setting up.
