Muff too loose for small engine

I have a Suzuki DF-30A and I've bought two pairs of muffs. Both are too loose. I need to use my hand or my feet to apply pressure on the muffs so that they are tight enough. Otherwise there's just no water flowing out of the tell-tale.

But this means I am smoking a fair amount of exhaust.

I can probably use a C-clamp to tighten it up, but, is there a more elegant solution to this?

Thanks!

I gather from looking online the DF-30A has what is described as 'an easy to access freshwater flush port'.

have you had a look at an owner's handbook?

Otherwise a large container that you can immerse the leg in as deep as required.

I have used the fresh water flush port, but the manual says when flushing this way, the motor should be off.

The manual recommends flushing with the engine on using muffs.

So I'll try flushing from a bucket. It will save water, too, which is good when California is in a drought! Thanks for the suggestion!

The container method - a dustbin/trashcan works - is also a good indicator that the pump is working well. A lot nicer for your neighbours too as its quieter!

Are the muffs the wire type? Bend the wire, and you're good to go.

It'll probably take a vise and either a hammer or a large pipe wrench though.

Personally, I use the flush port on my F115 (no noise other than the water hitting pavement.)

I prefer to use a dustbin for my mercury 15 but I have to take the prop off as I haven't found a dustbin big enough to use with the prop fitted

I always prefer to flush in a tub. I've used big floppy builders buckets, wheelie bins and as I have access to the big plastic 45 gallon drums chopped a couple of those .
I always think it's easier and less of a worry than if the muffs drop off and is guaranteed to circulate the water if the impeller is in good condition.

A couple of cable ties sorts it.

Same problem with my Tohatsu 20hp.
I use a bungee cord wrapped around the metal legs of the muffs pull tight to compress the legs inwards then I wrap the bungee cord around the power shaft of the outboard to double secure it.
Works a treat.

Thanks for the tips! I totally forgot about the top 3 "real men's tools" -- cable ties, bungee cords, and duck tape!

It looks like a lot of guys out there suffering due to slack muffs!
I wish I'd been a little more selective when I acquired my muff lol!

Having a selection of muffs is not an option when your married, especially if she finds out

To return momentarily to the flushing discussion.....

Somewhere on here I posted a pic of my solution - a couple of old cloths stuffed up the prop with a bungee to hold them in.

Works a treat for the noise. No help with the muffs tho'!

Back to the banter.......
