My grandpa (who just had his 92nd birthday) gave me his 1963 "ish" 5 hp (he thinks) Apache (Clinton engine) air cooled outboard motor. This thing is great. No plastic anywhere, pure pot metal. He told me he thinks he started in the 80's. I add a 1/2 pint of SAE 30 to a gallon of gas and it starts within a few pulls. No reverse, no neutral, only "go". Cant wait to put it on the boat and see how it performs while trolling. What oldish motors do you own that still function?
