Shopping for a new motor and found that the 40-50-60 HP versions of one brand all weigh the same. So why would anyone buy the 40-50 HP versions when the 60 is so similar, the resale would be better, and it's more versatile? My hull is only rated for 40 HP but as long as the rpms were kept down, the boat would never know. Especially with so many people trying to convert 9.9 and 15's to 18's and 25's, I'd be ahead of the curve to start with.
