Repowering with OB - Hp?

[mgarfield]

I'm looking to repower my V20. Currently it has an older Johson 120 2stroker. It can pull up a younger skier and will do +-35 top end with 2 on board. Considering putting on a 150hp 4stroke, but not sure if it is enough Hp. Any expereince as to if 150Hp is enough to pull up an adult skier? Would rather a 175Hp but options there are limited it seems. It also seems a 200Hp 4 cycle is too big and heavy - not to mention price. Any suggestions/advice/experience -- Thanks
