Help - Steam / Smoke

[paradave]

I know what your thinking .

Yup, I would definitely suspect the elbow given the improvement on mine after you recently replaced it. I’ll try and find a before and after video later and upload them.

Just you're satisfied you've got a clear run from the water pump, the only thing I can suggest is check for air leaks in the system. Mine saw some improvement after I applied vaseline to help seal the sea strainer lid

Both my 805‘s with the same unit produced that amount of steam.
if no black clag on the transom / platform and exhaust and cooling ok no problem
presume exhaust is above waterline at speed

Yes, almost all owners of these engines report the same condition so I conclude it's a characteristic of the engine and not a fault. The amount of steam does increase if, for example, the exhaust elbow has reduced flow, the prop has some fouling or the bottom is fouled.
