I used the prop calculator and got a recommendation of exactly what I have now. 9 1/2 x 10. Here is my situation. I have a 1959 14' v hull feather craft boat. 6 gallons of gas 2 batteries 2 10lb anchors, trolling motors 2 small coolers and probably 20 lbs of fishing gear. I myself am about 220. I run the batteries and tank up front and use the boat primarily by myself. The 1982 evinrude 9.9 pushes me about 16 mph. Perfect to me. When I put my 240 lb fishing buddy in the boat I run about 10mph. I don't even mind that so much but I spun the prop hub and need a new one. My thinking is (since I have no way to tell rpm) that obviously I'm turning way less rpm at 10 mph under a big load than 16 mph solo. I know lowering the pitch will lower speed, but wondering if the lower pitch will get my rpm up under the heavier load, Producing more hp, and may even pick up more speed. Since I have to purchase a new prop I'm concidering a 9 pitch instead of the 10 I have now. I know that may not be enough technical info to go on but I know a lot of you guys have enough experience to make a good judgement call. Any thoughts!
