over-boosting ...
...has been an ongoing problem with 914's ...
I'd go with the 912-S --- think that's why it was introduced !
Less complex than the 914, and more reliable, and with a
bit more power than the regular 912. Early vibration problems
have been resolved, and it looks like a clear winner in
fuel economy & reliability. Think I would use a GSC mechanical
in-flight variable pitch prop - only about $1,500 !! (Several
different blade choices, including W-D...)

Thanks again Bob, I will continue working on the floor.
The only reliability issues I heard re Rotax 914 were the possibility of a
vapour lock in the fuel system, and re both the 912 and 914, the possibility
of oil starvation due to slow oil return to the oil reservoir and some issue
with the oil pump. Apparently these have all been addressed by Rotax ADs.
I wonder if the Brampton 914 crank failures were related to the oil
problems.

Hi Paul !
Please put that floor in !!! You will virtually double the strength
of
the fuselage, and it's only about 5 lb. !!!
There's documented testing, and field results of damage, showing
that the rear double floor is definitely "A Good Thing"(tm). :-)
If you want to see some comments, i can send them offline, but
it really IS worth installing !! Remember, we had the floor, and
upholstery, and carpeting all the way back, in FINR, and others,
and they flew great !! Believe me, the difference rearward is not
as much of a problem as the forward C of G with O-320's, etc....
and they all fly OK toooooo ......
I think the 912-S is likely a better bet than the 914 - there have
been reliability issues with the 914 - a couple of broken crankshafts
on aircraft out of Brampton .... Should be great on straight floats.
My ideal 'retirement Rebel' will be a 912-S on amphibs ... :-)
Can't wait !
