To the OP, the hours are low on both boats and if you don’t mind spending the extra $8k for newer motors then you might consider going that route, if they check out. I’ve got a 2004 Yamaha F225 on my boat with just under 1k hours on it and it still runs great. I had the lower unit dropped and inspected for the dry exhaust corrosion issue, of which no issues were found thankfully. If they don’t have the problem then they’re pretty good and reliable motors. I know Italian Angler on here has I believe almost 2k hours on his, and I don’t believe he’s had the exhausts done, and still runs them on his boat. I think it all depends on your budget, your needs, how fast you want to go and so forth. The maximum horsepower for your boat is 500 hp, and I don’t really think you need 225’s to put you and 450 hp total. I think that 200’s would be just fine, of which my neighbor has a 270 Islander that has twin F150’s on it and they push that boat just fine. I think he said his top speed is in the high 30’s, which for me is plenty fast for being out on the water. I think 200’s on a lighter boat would probably put you into the low 40‘s for top speed. I’d call or email Grady White and see if they have the specs on the boat with both combinations of motors on them. I did that for my boat with the F225 on it and they emailed me back in about an hour or so. As always, I recommend having any boat/motor that you purchase inspected by a certified marine surveyor and/or outboard motor tech. Good luck!
