Just got a 1965 model 5502 serial 5502S-E05948 and have many questions about servicing the old girl. I bought it from the original owner who took religious care of his toys. The tag on the motor says it was winterized in 2000. It is a fresh water motor and under the cover it looks brand new.
Is there a better choice of plug than the Champion J4J?
Is it OK to use premium gas? I can only get Non-Eth in Premium.
What is the best 2 stroke oil to use?
Manual recommends 50-1 mix but others say to richen it up to 40-1 because of the type of bearings used.
Engine oil specified is 30W ML-MM or MM. Is there a better modern choice? Is detergent oil a consideration?
Gearcase oil specified is TYPE "C".... Is there a modern equivalent?
What is Lube TYPE "A"?
Anything tricky about changing the impeller..... Any gaskets, etc needed?
What else should I look for?
THANKS FOR ANY HELP.
