Im guessing they wouldnt have as much usable thrust as the 9.9 with
its bigger prop, but probably a higher top speed?

Shaun, as you can tell from the replies so far, we need to know your
intended use ....
a) pushing a displacement hull
b) pushing a planing hull
c) combination of both "a" & "b"
d) none of the above

Its intended as the main engine on a thunderbird 26. i am planning to buy
second hand, and have seen more of the 15's come up for sale than 9.9's
which is what i was hoping for. will be used for general harbour docking as
well as motoring longer distances when becalmed.
