Hi,
I have 67 Mercury 500 Thunderbolt. S/N 2168363 I also have the Mercury repair manual that covers years 66 thru 73 or so. How do I determine the particular model I have? The manual lists models with acronyms, such as SS, M and S, but doesn’t list what those acronyms stand for.
There are symbols that look like 2 lightening bolts after thunderbolt just above the exhaust housing. Is that supposed to be SS?
Clarification would greatly help in doing repairs with this manual.
Thanks for your help.
All the best,
Jason
