Quiet flushing
We've all been there. Running on muffs & waking up everyone within a 10 mile radius of the engine or p!ssing off the people enjoying a nice quiet pint in the pub on the front. I have solved the problem!
Take 1 bit of plywood slightly bigger than your prop hub diameter, 1 bit of bungee and an old cloth / rag.
Dril la couple of holes i nthe ply and use the bungee to hold the ply against the exhaust hole (hook it round the font of the leg above the gearbox- it wonlt fall off), bunch the cloth up and put it in between them. This essentially simulates the prop being underwater, and so the exhaust is forced out the idle ports via the silencer the way it was designed to.  The cloth allows the exhaust cooling water out & acts as a sound muffler.
Don't just use ply - it will rattle against the prop hub with the exhaust pressure trying to push it out thre way and double the noise levels!

Yes, it does involve a tiny amount of self control.....

BTW, I LIKED the noise my 90s used to make in the muffs. Good idea though - handy for late night flushing.

My neighbours already hate me.
I've seen me racing home during the summer so that I can flush the engine before the kids in the street go to bed. Having said that, their windows are usually open, and a Twatsoo 2-stroke reverberating with occasional revs (in for a penny in for a pound) seems to bring everyone to the window...FFS! I'll need to try this.

Brillant up to your usual standard. But I do hope you were not doing any 'underwater sport' in this vacinity or you will be pulling this thread down to the depths of the bil.......

My neighbours hated me when I had the 90 Yam. I chopped it in for a 90 honda and now I hate myself I doesn't make the right sound.

Happy memories. Flushing two of them really upset the wee scroats down my lane - pair of lads with noise boxes on their car exhausts.
Exhaust Envy is a terrible thing!

For that you need a couple of rolls of loft insulation to wrap yer cludgie in before you pull the chain.

The very reason I came up with this idea in the first place!

For the time I had a 4 stroke I really missed the muff noise!
200HP V6 4 stroke on muffs sounds amazing!
