I might end up putting a trolling motor on the back instead of the trade for more power, it would be cheaper also! Thanks for the thought!
Good luck with whatever you decide. I hear you about trying to figure out the way to get the functioning you want, but making it worth the cost. Outboards are so ridiculously expensive! I dream of upgrading my big old carb., gas sucking, stinking, noisy v-6 to something more modern. As a compromise I bought a cheap, old, but working kicker.<br /><br />RE: the idea of converting a 40 to a 50. I'm not saying the dealer is BS'ing you, but it would be the first time I've ever heard that it is actually practical to do it. This topic, usually in the form of converting a 10 hp to a 15, comes up very often. There are a LOT of engines that share the same block, but have different horsepower. If you look at any given manufacturer's web site, you'll see "groups" of engines that have the same weight, maybe even the same displacement, but different hp. But there are normally several different and expensive differences in the parts and design that boost the HP - it's normally not as simple as just changing a part or two. I'm no expert, but some that come to mind are carbeurator, manifolds, and various other internal and external electronic and mechanical parts. I'm just saying, that when you hear this sort of thing, be a skeptic. In the discussions I've seen, the general consensus is that somewhere down the road if a person tries to upgrade the HP, it ends up being cheaper to just trade it in on a new engine. The most economical way is to get the HP you need /want right from the get-go.<br /><br />I also hope that if I'm dead wrong, someone will correct me!
