As most outboard motor carburetors lack an accelerator pump, bogging can be a too lean setting of the low speed mixture screw. Carburetor float level can also be a cause (replacement of the inlet needle & seat assembly, and proper float adjustment would then be advised). There is no shock hazard with the ignition switch "off", but Do disconnect the negative battery cable from the battery, or both cables, to protect the ignition components when servicing (this is true for many outboards).
