And if you wish - I can talk you through a troubleshoot of the ignition.

1st test: Red on the switchbox (starbord side of box) outta be at +12 all
the time, when you turn the key on white will go +12. Switch is now tested.
Let me know when you get that far.

hi there,

I've been tinkering with a 1972 80hp merc that I got some time ago that
started, but has since failed to. It appears there may be a problem in
either the switch, and / or coil. Based on the prices of these old
parts
it
could be pretty pricey if they both need replacing (which I wouldn't
doubt).
My alternative to just not fixing it, is to get another motor that is
newer
and in good working condition for a bit more. I'm keeping my eye out on
those prices too, but have an important question to consider... Could I
use
a smaller motor?

This old 80hp has powered a 15.5 ft fiberglass boat. But could a newer
motor of a smaller HP do an equal or pretty good job? Perhaps a 40hp of
a
newer vintage?

Has anyone had experience changing motor sizes?

Chris
