Hi Howdy! Thanks for your suggestions about replacing the seals on my lower unit. I'm thinking of upgrading my 20 horse Johnson electric start. Some guys say buy a 2 stroke before the 2006 requirements make them more complicated. Some guys say buy a 4 stroke now that meets the new...
I was recently advised to use 105 weight oil for the lower unit to address leaking lower unit. This sounds questionable. Wouldn't it be better to reseal the gearbox & check the water pump (even though it seems to be pumping fine)?
