"Hi,

Got an old (late 70's) 140hp 4cyl merc with the old contact point distributor. I know you can upgrade this to an electronic breaker with Pertronix, but I think the centrifugal advance etc is also worn etc and I would like to just replace the lot with a modern ignition.

Is there any reason I cant put in a salvaged digital ignition system from the slightly newer 140 such as this:

The only reason I can think of is if the timing advance is different between the engines then it may not work well at the higher revs as I guess the rate of advance is hard coded into the control module.

Anyone ever tried it?

thanks

Anthony"
