196? Evinrude 60hp Problems

[John_Matthews]

Hi,

I have a mid 1960's 60hp V4, model# 60553C that's giving me problems. It's very hard to start and when I can get it going it won't rev and tends to die after a few minutes. I was given the boat & motor so don't know exactly when last run but about 10 years ago.

Here's what I've done:

Replaced the impeller and lower unit oil
Checked timing & point gap
Checked for sheared flywheel key
Cleaned carb
Confirmed fuel pump working
Measured resistance at points (coil seems good)
Changed ignition switch (3 lug version but have jumped coil wire to battery)

I consider myself a pretty good mechanic (I run a shop and fix other people's stuff), but this one has me stumped. It'll crank and fire but not stay running, but sometimes it will run for a while, while other times it'll just build up fuel in the cylinders until it goes BOOM and my dog looks at me like I'm some kind of international terrorist. Please tell me it's something stupid like the wrong ignition switch (does anyone have a spare #25 key?), or bad condenser....

TIA,

John

Re: 196? Evinrude 60hp Problems

sounds like intermittant spark from a coil(s). If you have a coil with a crack in it, it might work for a little while and then go dead on ya and then come back to life only to do it again.

Is your mag timing correct?
Do you have a bright blue spark and does it jump 3/8' air gap?
What is your compression like?

EDIT: I forgot, by your mobel number it is a 1965.

This may not be much use to you but i thought,.... I had an old 60hp evinrude a few years ago, unable to get parts i experimented a bit. Put on a coil and condensor from a chev cavalier, had to bend mount a bit to get cover on but worked really well.
