I saw the PS engine run in MN at a big fly-in this spring. The only
vibration problem I noticed was the guys  cheeks as he stood behind the
prop. However in a boat there is generally much more bouncing...even more
than my landings. Will a rigid epoxied joint  hold up. Just occurred to me
that the o-rings and clamp would afford some flexibility.?

I would think you would have to support the pipe between wiggins couplings.
When you install them make sure they are not bottomed out. The pipe length
will grow somewhat as it heats up.
