Short Shaft vs Long Shaft for a trolling motor question

[JandSGuns]

I have a 14' fiberglass fishing boat (Livinston Tri-Hull). I have been using a 1967 9.9 hp Johnson short shaft trolling motor. That motor runs beautiful. Starts on the 2nd pull every time. Never had a minute of trouble with it.

Recently I had a friend that bought a new boat and motor. He then gave me his old motor, a 1983 Johnson Seahorse 9.9 hp long shaft trolling motor. (16 years newer than my motor.)

I am a novice when it comes to boats and motors.

Other then the length, is there any difference in a short shaft vs a long shaft?

Would the long shaft work on my boat?

Any thoughts here on switching to the newer motor?

Thanks

Dave
