Today I was reunited with my Father's 20 HP Johnson SeaHorse. I was originally purchased in Canada. Model #: 20BA76E S/N: C 45854. I wish to find web links and other info on this motor. Can anyone tell me what I have and what the model number tells me? I also require parts, throttle adjustment knob and linkage, tilt locking bar, and transom clanp handle. Thanks.
