Recently upgraded the dinghy to RIB. The 6 HP will not get it on the
plane easily. Any effective suggestions on increasng the output of the
O/B. ie carby jets or exhaust restriction.
Thanks in advance.

Depends upon the engine, but I'd recommend against it for long-term
reliability, having played with small engines in my youth.

Unfortunately, the answer lies in more horsepower $$$.
RIBs go faster but need bigger engines.
What size is the RIB?

The good news is if you must buy a new engine and replace a two-stroke
with a four-stroke it will save fuel and run significantly quieter. and
no smoke or smell.

RIB is 2.7M (9')

About 9.9 horsepower should make it fly. But to be certain, check the
manufacturer=B4-s rating. Less than about 20 percent of max is too
little hp. Result: Slow to plane, if it planes at all, and less than
exhilarating top speed. Performance is dragged down even lower by
passengers and Jerry jugs. My avon 3 meter does fine with 9.9.
