1969 vs 1970

[jgrice]

I have a 1970 Johnson 25R70 and and have a chance to buy a factory repair manual for the 1969. Are there enough differences in the two engines that I shouldn't buy it? Thanks for any input.

The 18,20,25 and 28 are all in the same section in my
Intertec manual.It appears basic specs and procedures are the same prior to 77.

Thank you, Steelspike. I was pretty sure they were probably close enough to use the manual for either, just wanted to make sure.
