I had a 15HP 2 stroke Evinrude, same size and weight as the
9.9HP, on a Coronado 25. Worked great, the 9.9 may have been
enough? Don't know what your well configuration is but if you
do some measuring beforehand you should have an estimate as
to whether it would fit. Suggest you get a long shaft version.
The high thrust props were not available then so we went down
an inch or so from the stock prop and had all the thrust we could use.
We used the motor hard for 10 years with no problems.
On my present 2 stroke motor I switched to synthetic 2 stroke
oil, same 50:1 ratio, and the smoke was noticeably reduced.
