    62 Johnson 40HP OIL MIX THEN AND NOW ....WHY??

    Well time on my hands I was thinking ( Yeah it hurts some times) Engine always used before me 1 qt 30w oil to 6 gallons of gas.That is a 24:1 Ratio right? Ok fine BUT NOW it's recommended to use 50:1 ratio with 2 stroke oil. Engine runs both ways BUT why 50:1 with 2 stroke oil? Some one maybe...

    Generator on 62 Johnson motor

    OK old motor fans here we go. I'm putting two batteries in parallel on boat. I was asked if the generator on my 1962 Johnson 40HP motor would be able to handle that. So here I am asking the experts. These batteries are regular car batteries as well. Any thoughts on this?

    Well kicking along great found bad spark plug wires & changes coils as well "found a cracks in both as well".

    Gear case oils

    Went to boat store & got handed Mercury 80-90 gear lube for my "1962 40HP" motor on my 1967 Starcraft. Didn't seem right to me so I passed on it. Can't seem to find "Johnson Hi-Vis or Ultra-HPF" that it calls for. Any alternatives or just keep looking? You have been great with me asking...
