which do I choose?

A little late, but we have a 24 foot sweetwater with tri-toons and a 150 HP Yamaha 2-stroke(HPDI), top speed with 500 lbs of people is 43 mph(gps speed, keep in mind we have the tops down, smooth water, and trimmed way up). Right after break in we had a rush of people who wanted on, my guess is if someone had weighed the weight of people we would have been near or over capacity(we had 9 adults and 3 kids on), and we were able to maintain 20 mph pulling a tube through corners(straight away's it was around 24).

We are able with 4 adults(3 of us are big people) and 4 kids to hold 40.5 mph trimmed up. I will say though the 150 2stroke is very fuel hungry when it passes 4500 rpm. With that said more horsepower is always a want for water sports on a pontoon, but overall the 150 is adequate.(you must keep in mind prior to this we had a 19 foot I/O deepV ski boat with a Merc 305 V8 with a power prop so this is way different)
