I've been contemplating going with a 175hp over a 150hp but my dealer doesn't recommend it due to minimal noticeable difference in power. I think going to a 200hp would put me out of my comfort zone on the budget but not totally out of the question. Is the dealer right about the no real difference in power? To me 25hp should be noticeable but he says it's not worth it. I'd just like a 2nd opinion from you folks. Thanks. The boat its going on is a 23' swingback with sps package.
