Identifying the outboard motor I should choose

I have a 14'8" Blazer Boats Tri Hull Without the Motor. It used to have a 55 evinrude. It says inside the max is a 90HP. I know someone who has a 90HP evinrude and a 55HP Johnson. But before i buy anything I wanted to know if There is a certain shaft Length I need specifically for this Style Boat or if it even matters. and if its the boat or the motor that would allow it to have power tilt and if they are interchangable.

Welcome to our forums.

If you measure the transom from the top of where the motor mounts to the bottom center of the boat you will find out which motor you need for the boat.
Fifteen inches is a short shaft and twenty inches is for a long shaft engine.
Power tilt/trim is a feature of the motor and should work on most boats.

The size of the motor you use would be a matter of how you will be using the boat.
A larger motor is always good but you need to balance increased fuel consumption and weight against the added power.

One thing I see that seems to becoming more popular is an added small engine for a back-up and trolling.
A smaller motor will allow a bit more space and weight capacity for a second motor.
