I had a 40 HP Johnson which fitted nicely into a dustbin. Engine on
Shetland, 'dangling' into the dustbin filled with water to the correct
depth. Keep an eye on splash, keep the revs low and keep topping up if
required with a hose pipe.

The only thing you can test in the "dustbin" is that it starts and idles OK.
Overheats - ignition problems - and full power problems probably won't show
up. Outboard "test tanks" are specially constructed unit that allow extended
full throttle tests. The other option is to find a "floating boat tied to a
strong pier" to do your test.

and if indoors in a workshop, has an extractor fan to take away exhaust
fumes and a method of keeping the water clean via filters etc etc etc. I
don't somehow think the original poster quite had this in mind :-))

Why not use a pair of 'Muffs', these fit like earphones over the water inlet
and have an inlet for your garden hose, also useful for flusing out cooling
system after use.
