I have had a skeeter with a 75hp in the past. My Brother-in law has a Bumble Bee with a 150.
I got the Skeeter in 1988 when my kids were small and we did the family stuff. Pulled them on ski and tubes. It was a bass boat primarily, but it was fine for the family trips. I agree with the others here in that if you get a fish and ski you have neither a fishing boat nor a skiing boat. My primary thing was fishing and it worked great for that, but it worked fine for the periodic skiing trip.
One thing not asked is what type of fishing will you be doing and which type of lakes are you planning on going to? I had been looking for two years to get a new boat and looked at all those makes. I have heard from more than one person that the Tracker Aluminum boats are not high on the quality scale. The Lowe boat I have is absolutely impressive in the quality and layout. However, the fish and ski Lowe model is really the deep water hull. That tends to be used more by northern fisherman for walleye, trout, salmon, etc. It is not for bass fishing and trying to get up in skinny water when you have to. The stinger models 190 and 195 are 18.5' boats and are wide. They can handle up to a 115. The hull is a modified V and rides very smooth in all water. I took my 175 on Pickwick and it was a much smoother ride than my old skeeter.
Starcraft and Lund are primarily Deep V hulls and have always been a big water northern type market boats. Again I would be wary they will not handle shallow water well.
Also Lowe currently has a $3,000 dollar rebate until end of March. The place I got mine is advertising a Stinger 190 or 195 for about $16,000 with a 90HP. Jaco's Marine
