Hello. I looking to buy a Princecraft 192 deck boat. It weighs approx. #2300. The standard motor is a Mercury 90 hp. A 150hp is a $4000 up charge. This boat will be used on small lakes for fishing and general pleasure boating with pre-teens.(and a dog) .Nobody knows how to water ski or anything but I think they will enjoy tubing and trying to wake board. Would a 90 hp. be sufficient to pull some one out of the water? I know bigger is better and the new 150 4s is nice but $4000 is a lot. I can't seem to find a way of comparing these things. Thank you
