My son and I just came back from the lake and we both thought the engine was running very well. We have 1962 crestliner with a 1966 60hp Johnson. We would slow to a crawl as though I was towing a skier then I went to full throttle. The motor reved up and stayed that way until we planed. If I sat up on the bow the boat we planed within a half a minute or less. If we both sat in the front two seats and repeated this, it took up to 3 minutes to get up and planeing. Once plaining, we flew, I don't have a speedometer but it felt like 35-40 mph. Someone told me that if there are nicks in the prop, that could inhibit performance. I just removed the prop to exam it. It is a Michigan and it says on it P J 7:5. I have a Johnson service manual and the recommend five different Props. 9-1/2"x10pitch, 10"x9-1/4", 10"x11", 10"x12", and 10-1/4"x10". What does this all mean??? As I oberved the Prop on the motor, I noticed that there is only 1/2" left before the blades of the prop would hit the bottom of the decavatation fin. I do think a different prop would move the boat along better. Can anyone make some recommendations?? Any comments on this?? I have to say that today the motor seemed good. No skipping no sluggish feeling. I redid the lync and sync and I checked the timing, all is good.<br />Thank you very much for the input, we're still having fun.<br />Mike and son Zach, still digging it!!!!! but would like to get the boat running better.
