i am looking to repower my 15 foot glastron gt 150. i am looking at a 90 hp johnson spl motor and also considering a 90 hp yamaha. the boat is rated for 90 hp but iam concerned about the weight difference, i am guessing the yamaha to be about 270 lbs. but not sure about the johnson, does anyone know the weight of this motor. thanks, keykev..........
