[QUOTE="thill, post: 503531, member: 4972"] I took my boat out to lake test it, and found that a 15P prop was WAY too flat. It leaps out of the water like a jet ski and will run over 6K in seconds at around 30 MPH. I throttled back and took some video: [MEDIA=youtube]DCM2ZxjH8I4[/MEDIA] I found a 17 and a 19 pitch in my prop pile. I'll have to figure out which one next time I get some time. My guess of 35 or so should be right, but it might do 40 MPH at this rate. Engine ran well, but it makes a funny sound. There is a ticking sound I'm not used to hearing, about once every second or two. It sounds like a slow clock. It's not related to the RPM, I don't think, and it sounds electrical to me. I suspect it has something to do with the power pack going out previously. I found a strange grounding issue with the tilt trim system before. When I used the trim, the small internal ground cable between the trim and the block and the midsection would get hot. I disconnected it and the problem went away. This makes me feel a little cautious about taking this engine too far until I figure it out. [/QUOTE]
