Re-powering my seacraft

[FishStretcher]

I have a 356lb 100hp 4 stroke on a 20 footer and I like it just fine. I get the feeling that the water is often flatter in Florida, so you can take advantage of big power on little boats, so the combinations down there are sometimes a bit different from the those in the Northeast.

I would think that a modern 90 on an 18 footer would be a great combo for performance and on the wallet. And still fine for a 20 footer. Spend a little time on prop tuning and selection to maximize the potential.
