I have been running B3 aluminum props on the SeaSport, and have switched out to C2 stainless. Everything seemed to go together ok, but upon starting her up in Whittier last week I experienced a "thumping" sound when I shifted into forward gear. Shut her down and looked everything over. No visible problems and I could easily turn props with boat stick.
After playing with it at the dock for a few minutes I realized that it thumped immediately when it shifted into forward. If I pushed the shifter just a small amount more it was quiet. Pushing the shifter handle was not enough to increase the rpm. It was still at idle.
Took her out of the harbor and turned a couple of circles to test out on step and everything was good. Ended up going out for a few days with no increase in problem. (NO decrease either).
Now at home, I need to address this problem. I am hoping its a shifter cable adjustment due to the much increased weight of the stainless props. I have never fiddled with the linkage under my shifter throttle and I was hoping someone here could offer some experience on this subject before I dive in and try to fix it. Any information or tips would be much appreciated.
