It depends on many many factors. IE;
What is your application? Off shore racing, lake racing, bass tournament
fishing, water skiing, trolling for fish, running a charter boat, gentle
curse on a small quiet lake?

How long is the boat? 8ft, 80ft, 800 ft?

How much is your budget?

Factory built outboard boats built in the past 40 years or so have a name
plate showing the maximum rated horsepower.

You might get a better reply at your local boat dealers.

If you can be more specific, we might be able to offer some suggestions.

It'll be fun to play on; might pull knee board or innertube -- but not fast...

It's my considered experience that the minimum HP for a 16-18 fiberglass
runnabout to do any kind of "pull-toy" work is 90hp. This from someone who
had 80 - 90 - 115 - 135 hp on the same boat in the same season. A really
light boat can get away with a 70hp. And remember to prop it correctly for
pulling stuff if you're at all low on HP.
