O.k. here is the scoop.. i've got a johnson 9.5 that i've been having trouble getting to pump water, i think ive narrowed it down to a grommet and a gasket at the base of the motor..how big of a deal is it to remove the engine so i can replace this gasket and grommet?? i guess what im asking is what how in the world does this thing come appart?? and is a job that a novice could do??(never been into one that far).. i would appreciate any advice i could get from someone that knows....thank you. also any parts i might need to replace while i have it apart.
