these boatys are nice with a 150 on them, but some have as low as 115, and others as much as 225 All depends what you are looking for, if speed is nothing to you the small s fine if you want speed then a 225 but you will only get to use it on the flat days, 150 is right down the middle and IMO all you will ever need
My power is a 150 HP Honda...I was looking for reliability and got it... since installing in '04, she's been tuned once, oil changed every 100 hrs (approx)..very efficient on gas if I don't get into the upper RPMs
I've got a '92 CC with '92 200 Merc, and my weighs in right at 2000 lbs. on our forklift scales. That's probably with a 3/4 tank of fuel (45gal.) and 5 gal of water.
