Hello everyone.. I lost my propeller on lake biscotasi last year, just happenened to be at the farthest end of the lake away from my camping spot before sunset, yadda yadda, long story!! I purchased a new one last week and installed it to manufacturers specifications. The motor is a 1994 9.9 johnson and the pitch of the prop I purchased was a 10 pitch.. So i start the motor for the first time this season and it fires up effortlessly as usual. Slip it into gear and away I go..I noticed at half throttle the engine was revving higher than usual. After a few seconds maybe 10, the motor kicked in and the I could feel the boat glide into what I feel is normal full throttle behaviour. For the entire evening my baby performed poorly for me on start up as described but ran smoothly for me at full throttle.. Could this be something to do with an impropper pitch??
