Re: mercruiser 3.o

from the pics, it looks like it was repowered some time in its life with a newer 3.0. the 84 vintage 3.0's had stamped steel valve covers.

I dont know if they did. My neighbor bought a new boat, and its still points. I want to get rid of points, trying to decide to go Pertronix or something else.

I put a Pertronix in my 2.5l. If you do it go with the Ignitor II and Flamethrower II coil. My dad put a Pertronix in his daily driver 1966 Mustang about 15 years ago and likes it.
