I bass fish motoring up stream with an outboard at idle most of the time. The streams are to swift to use an electric motor. The sound of an outboard motor running has never has seemed to bother the fish. But the main problem is vibration. I have been using a 1977, model # 10R778, Johnson 9.9 that I purchased new and has, for the lack of a better description, a suspension system that does a great job of off-setting any vibration problems and is very quiet. I fish about 100 days a year so this motor now has many thousands of hours on it and I would like to replace it with a newer one but can't find one that does not have excess vibration. I have purchased and sold a 2004 Yamaha 8 hp that did not solve the vibration problem for my use. And I have tried a 1971 Johnson 9.5, with only 8 hours of use and it also vibrates a lot. No dealer will let me try out a new model. Even though one can try out a new automobile or a new lawnmower or even a garden tiller. Go figure! <br />Question #1; which outboard manufactures of 6hp to 15hp with 2-cyl in a 2 or 4 stroke design have made an effort to address the vibration problem with the newer models, if any?<br />#2; how long did Johnson make the model like my old motor?
