Re: Year and model # of this 18 HP Johnson
1964 model with electric start.
Great motor, I have two and love them. Easy to work on, run great. Check the lower unit to make sure it is filled with clean gear lube and not water before you buy. If it needs seals, carb kit and coils, which is typical, plan to spend about $150 in parts to bring it back to A1 running order if all the mechanicals are good.
