Does any one know the optimum outboard shaft size for a Hunter 25. My boat is a 76 and the bracket looks like original equipment, a long shaft seems it might be to long. The boat is new to me, with no motor.
My original motor on a Hunter 24 was a 8 horse long shaft. I now have a new Hunter 24 with a 15hp standard shaft. Except in very high waves which cause ocassional cavetation I have not seen much of a difference. The extra hp gives me a little more stability coming out of the harbor, but of course it will only go 6.5 mph no matter what size engine.
The 25 I had came with a 9.9 long shaft Johnson and it worked well I bought it from the original owner who said he had order it this way. It was a great first boat. Good luck
IMHO When I bought my 74 Hunter 25 it was minus a motor and also had the original factory motor mount. I tried short shaft 9.9 hp and was not satisfied with it. I now have a 15 hp long shaft with a sail work prop, electric start and charger. The motor is only operating at 1/4 throttle to achieve hull speed and actually weighs the same as the 9.9 but the difference the prop makes is amazing. In reverse you have very good control and in forward it moves my boat easily and is great on gas.
My '78 H25 has a Yamaha 9.9 short shaft on it, and we find that we need to keep people off the foredeck or the prop will come out of the water! Also, in heavy following seas, the motor can be swamped(!) as it sits fairly low on the transom. If I had the choice (i.e., I had to purchase a new motor), I'd go with a long shaft. --Jon Bastien H25 'Adagio'
