Hello Group, I have been lurking here for about a month, but decided it is time to introduce myself and dive in with an issue that has me a bit perplexed. BTW, I picked up my new 15 last weekend, and, if the weather cooperates, I'll be stepping the mast in my driveway for the first time on Sunday. I hope I can reconstruct Bob's instructions. If I can't, I now know where to turn for assistance. :-) Before I get around to the rigging business this weekend, however, I would like to seek your advice on an issue with the motor I just purchased. I know the Honda 2 hp is widely used in the Montgomery community, so, when I saw one advertised recently in the Denver area, I jumped on it. It had been very lightly used, the price was right, and it seems to generally run well. Now for the complicating factor: I live at 8K+ feet in the Rockies and will usually be sailing at altitudes between 5 and 8,000 feet. I read in the owner's manual that engine power, even if properly modified, will decrease approximately 3.5% per thousand feet of altitude. I expected that with a conventionally-carbureted engine, but when I called a local boat dealer that services Hondas, the technician I spoke with was not exactly encouraging about the Honda's ability to idle properly at altitude, even with the fuel mixture leaned out a bit. I did start the engine again yesterday, and while it runs fine at higher rpms, I did have trouble keeping it going when throttled down to the point where the clutch disengaged. So my question is..does anyone in the group sail at altitude and use this motor? Can you tell me what your experience has been and whether you have had to, and were successful in, adjusting the carb to achieve a smooth(er) idle. Did you feel you had lost a significant amount of power while underway? Or, if you just want to weigh in with your thoughts, I would certainly welcome them as well. Many thanks.
