71 Johnson 60 Hp need help/advice

[Neil G.]

Hi there, first post on forum so hope it makes sense! I purchased a 71 Starcraft SS with a 71 Johnson 60 hp ESL "C" motor on it from Minnesota this past June. Anyways this is my first boat and I'm detrmined to do all work on this baby myself!
I have been having intermitent spark issues, when turning key to on position I hear a humming/ buzzing sound from motor (seems like comimg from Amp) and then it fires up. But every now and then (when about to launch boat it seems) I lose that humming/ buzzing sound and it won't fire and has no spark! The other day I noticed the starter bendix was not disengaging from flywheel, so a shot of wd 40 solved the problem. I then put in a fully charged battery and have had no problems the last 4 days.
When turning key to on position just prior to turning engine over (engine cover off can hear best) should I hear that humming/ buzzing sound from the motor?
I took red wire from Amp off the power panel and when turned key to on position no hum/buzz and when put back on got the sound back.
I'm wondering if I'm even supposed to be hearing the hum/buzz sound and if I have a bad Amp!
Thanks, any help on this would be appreciated.

Just realized I have the after market CDI Ignition module which is wired completely different than what service manual states. Now I can do proper tests as stated at http://www.outboardparts.com/omc/troubleshooting/stators/troubleshooting113-7123.htm
Also, good news on the hum/ buzz sound at bottom of CDI module instructions:

NOTE: When you turn the ignition on, you may hear a high pitched whining noise coming from the CDI module. This is normal depending upon the battery voltage.
Thanks

Starcraft16SS here is your boats twin!
A 16' 71 SuperSport with a 71 60 hp Johnson!
Bought for $1400 north of Minneapolis in early June, needs some work but figure I will have a bit of time (Nov-May) to do that. The disadvantage or advantage depending how you look at it of living in a land where we put the boat away and pull out the snowmobile!

Re: 71 Johnson 60 Hp need help/advice

almost a twin...same year make and model ..same 60hp Johnson Outboard .....
*you have the blacked out windshield frame like ezmobee has on his 1976 18ft Starcraft SS
*CMC unit is like paulp64131 has on his 1972 18ft Starcraft SS
I see you have something extra between the transom and the outboard that I don't have...
aftermarket CMC trim/tilt??? how do you like/love it???
My outboard motor cover was loosing/missing the aluminum 60HP badges/tags..the old
adhesive had dried out too much...used small(1/8th inch) pop-rivets to put them back on..

Looks like someone used some nice wood for the dash on your boat...
In the pm message you sent me you asked about my dash...I added the Tach...
it did not come with the boat...
The small old-time chrome steering wheel on the bottom left corner of my dash controls
my spotlight...
You also said you replaced the fluid in the lower unit...did you make sure to use the blend???
Our 1971 60HP Johnsons require a special blend for our Hydro-Electric Shift system
to work properly..

Your boat looks very nice..great paint on the hull...lucky you...
