SO after a few lobstering trips (lots of starting and stopping of the motor) my 60 HP Johnson has decided to be tempermental.

Sometimes it fires right up, other times the solenoid only clicks and the starter doesn't spin.

I bypassed the solenoid and went straight to the starter and things started right up. I cleaned my connections etc.
It is tempermental but the solenoid always clicks.

Before I drop the cash, is it the solenoid? The battery, connectiones, ignition switch etc all seem to be fine.

This is a little deal but I need to get back out to hoop netting and the budget it tight :)

If you can jump the terminals of the solenoid and it starts, then it sounds like the solenoid to me.

It is possible to have bad connections on the key switch though.

An OEM replacement solenoid is only about $25. This has to be the least expensive replacement part on the whole motor. If you thing there is a problem with the solenoid, replace it!

It is possible that this solenoid makes the clicking sound as it normally should but that it is still defective. While this condition is very rare, I have seen it a couple of times. So it does sound like the solenoid is bad.

Hey Phil,
If it takes you a while to get the motor fixed, you'd be welcome to buzz up to Oceanside and run out with us after bugs.

I just remembered that one time that I had this OMC solenoid that clicked but seemed defective I sawed the thing in half to take a look. The way it works is when the solenoid is activated a thin metal disc is pulled up and bridges the connection between the two main teminals going from battery to starter. Maybe the disc wasn't being held tightly enough onto the connections or maybe it was corroded where it made contact to one or both contacts but it had been moving properly and still was defective. The clicking sound is made when the disc hits the contacts.
