Ok I have a 1988 115 Mairner (0B24B487) that has a busted piston that took out a water jacket. All of the electronics are good, I think.

My question is will a 1974 115 Mercury (4842874) be able to convert over to the newer style of electronics.

I have a lead on a whole boat which has the 74 merc on it, and they say it has 10 hours on it from a rebuild, runs and a water test is pending. Needs a new impeller. So if i pick up this boat and have trouble with any of the electronics, I would like to know if my stuff will fit on it.
