I'm starting to think about getting my old boat and motor ready for the ice breakup in a couple months. Last outing last year, I finally got the old girl to run reasonably well after getting carbs rebuilt and finally playing around with the mixtures long enough to get it to both idle as well as accelerate to plane. However, it took between 15 and 20 seconds to get wound up to top speed, which according to the app on my i-phone was around 4400 rpm and 25 mph. It is on an old 14.5' fibreglass runabout, has a 15" pitch prop and the lake is at about 3700 ft. elevation. I'm thinking I should probably go to a lower pitch prop, but not sure if I should go to 13" or all the way to 11". Suggestions?
