Scott,
It is rated for a 15 hp. I ran a 15 Johnson on my 93 until last season. If you hunt alone with a dog and gear you will be fine. Anything more and it will be under powered. I just put a new 25 hp Yamaha on mine. Plenty of motor. My only concern is the TDB motor mount integrity. Ratings are 6 persons or 650 pounds or 965 pounds with motor, persons and gear.
Hope this helps.
