I am considering a super sport 170. My concern is that it might be slightly underpowered for water sports. I'm 6'5", 220... Not sure 90hp is sufficient. I currently have a dauntless 200 which I like quite a bit, but need a bit shallower draft as getting to the bay behind my house requires going through a couple tight spots. Last night I had the toughest workout in 20 yrs pulling the dauntless through a sandbar.
Anyone have thoughts or experience with putting a larger than spec engine on a whaler?

The Boston Whaler Super Sport 170 was designed for a maximum outboard weight of 415 lbs.
I suggest you research the various brands of motors available with particular attention to the outboard weight in the horsepower range you want, without exceeding the 415 lbs.

I highly doubt it.
It's about propeller selection. I would first try buying the same prop included with 2" less pitch and use that for skiing, tubing and wake boarders .
For repowering:
While there are several engine choices under that weight limit, there is a sizable cost involved.Boston Whaler sells all models with Mercury motors, no exceptions. It is illegal to sell a new boat overpowered.
You will need to find a separate outfit willing to buy the "used but not used" motor, derig and install a different engine.
I would estimate swapping to a 115 hp motor DFI or 4 stroke will cost you around $5K when all done.
Modern Boston Whaler's have a high weight to horsepower ratio. Models prior to ~ 2000 are much lighter.
One example:
2003 - current Montauk, 1400 lbs, max hp of 90.
2002 and prior Montauk, 900 lbs, max hp of 100.
