I am using a 9.9hp 2 stroke Nissan as a kicker on my 17' Fisher Deep-V. The Nissan has the stock 3 blade prop and I am wondering if i would notice a big improvement going to a 4 blade prop. Has anyone else had run into this situation and switched props and found that it helped a great deal? I am looking at this one from Solas: http://www.cabelas.com/prod-1/0031313017666a.shtml *I often fish 10hp restricted lakes and while trolling isn't a problem I am having difficulty maneuvering tight spaces like the docks etc. when only using the 9.9. (Handles like a barge.) Also, I feel like the prop is "slipping" at high rpm's since it is not pushing the Fisher nearly as fast as it did the basstracker. I'm not really worried too much about top end, but I'd like to see if I can find a solution to improve maneuvering at slow speeds - short of buying a new Yamaha high thrust 8hp or 9.9hp.
