For some reason, I couldn't get the muffs to work on my Yamaha. They
were the most expensive sold by West Marine, and they seemed to fit
fairly well, but even after about ten seconds of running, no water
came out the telltale. That's why I got out the tub.
I don't know about your area but we have a "Barrels, Boxes, and More"
where I can pick up a 55 gallon plastic barrel for about 40 bucks. Cut
it down a bit and I am sure you could fit most OB legs and props in
there.
