Hey Steve M. ... glad to hear progress is being made ...
So ... were you using black iron pipe nipples? to roll the unit
around and out? 3/4 NPT nipples?, or, actual 3/4" O.D. pipe pieces?
How long would you say they would need to be to work best, and, how many
is "a few"?
I'm surprised Uniflite didn't install one of those Onan Aqua-Lift
muffler systems on your setup ... they did on mine (early 1979 build)
... my gen-set is installed ahead of the Stbd. 6-71N engine, otherwise
sounds pretty much identical to yours.
Did you have any trouble sourcing the new exhaust manifold and riser or was it just the riser than needed replacement?
I'll have to examine the base of mine and see if the plate is held
(clamped?) to the plywood shelf by 3 wood screws like yours was ... don't
suppose you took any pics of same eh?
