My spelling is bad and spell check isnt working ..sorry
I'm have trouble conforming to normal practices with my exhaust
manufacturer recomends no more than a 40" rise of the exhaust
due to back pressure.
Given my configuration I would have to lift
the water lift
up to high to have a safe distance between it and the engine
I'm thinking to extend my exhaust drystack up about 3 ft +(behind my companionway
ladder) do a "U" bend at the top, then inject the cooling water
Then straight down with hose into the top of a water lift...this I'll fab. and will basicaly be a 10" dia fiberglass
cylinder on its side.
The outlet FG pipe will extend down to with in an inch and a half from the bottom of the cylinder.
The outlet hose goes up to high spot (but lower than the dry stack) then slopes down until it exets the boat about 6" above the water line.
This is all pretty normal ecept for the extra high dry stack.
It seems that with the high spot being lower than the drystack that it would be almost imposible to ever flood my engine.
I know that I'll have additional insulation
and vibration considerations but am sure I can deal with them.
Is there any other reason for not having an extra tall dry riser?
