[QUOTE="thill, post: 503687, member: 4972"] 30 mph is not bad at all for a 50 HP on a 18' boat! I'd be pretty happy with that. Yesterday, I replaced the impeller in my water pump, and I also put on a 19p prop. A little high, maybe? Nope, it hit just right, as rigged. 39 mph at 5700 RPM when trimmed perfectly, which is the proper WOT for that motor. That little boat moves well. Here is a short video. I was playing with trim, so it took a bit to hit the right spot. Only ran 38.2 in the shot, but good enough for a quick demo: [MEDIA=youtube]4JLA9kuIi54[/MEDIA] Once I install trolling motor, batteries, seats, carpet and people, I'll probably end up with a 17 pitch prop, which I have. I'm guessing I'll probably be running about 35 then, but we will see. Flying solo was pretty fun. Speaking of flying... While taking video, an AIRPLANE did a touch and go in front of me. Not what I was expecting to see! You can see it at the end of the video. [/QUOTE]
