Default Mercruiser 3.0lx clicks but does not start

I have an inboard Mercruiser 3.0lx. I have two new batteries. I tried bypassing the ignition by placing a wire from the soleniod to the battery and the boat starts right up. What can I do? I was considering trying to run a wire straight from the ignition to the solenoid and the battery. But not too sure how to do that.

I need help or I will end up back at the repair shop before the summer is even started..

Check all of your connections at the battery and on the engine, make sure they are clean and tight. It sounds like a loose or corroded connector (positive or ground).

If the solenoid is clicking and the boat starts after jumping the two bolts on the solenoid, then the selonoid is probably bad and needs to be replaced. An easy fix for about $15.00 .

correct, but make sure you use parts for a marine application.

Combat, where did you jump the bolts, at the starter or at the starter slave solenoid (not attached to the starter)? If you jumpered the starter slave solenoid then that can indicate a bad solenoid but from the symptoms you gave (clicking) it sounds like you are just not getting enough current to the starter to turn the engine over. If you went directly from the battery to the starter then you bypassed all possible bad connections and had sufficient current to start the engine.

I would replace the whole starter then fix the one for a spare--- you have to remove the starter to fix the solinoid---- Better yet find that place that rebuilts for /swaps for $ 49.00 as posted on Volvo post

Didn't read the click part...definitely a solenoid. Joe is correct. GM starters use integral solenoid to energize starter and slide bendix out to engage flywheel. Easy fix.

Default Re: Mercruiser 3.0lx clicks but does not start

You have another solenoid or a helper solenoid, or starter slave solenoid in the system. They are usually mounted on the engine. These are known to go bad. When they do they will not allow the primary solenoid above the starter to engage! Symptoms are a clicking sound like in a weak battery.
A GM starter has the primary solenoid above the starter that when engaged move the bendix into the flywheel gear. So I doubt it's the primary solenoid, since he jumpered the sytem and it started. If he were to bypass the primary solenoid the starter would just turn and not engage!

A wire color of red/Purple, with the other side of it red going to the main solenoid above the starter.

I agree with Kevin, clicking would indicate that your solenoid is trying to do its job but the starter is not getting enough juice to do it. Since you were able to bypass everything and start it I still think that your battery is good but you have one or more loose/coroded connections somewhere. If the starter slave solenoid was bad you would get nothing and if your starter solenoid (aka bendix) was bad you may hear a click followed by the starter spinning but not the engine. Just clicking would indicate that the starter is engaging the flywheel but cannot turn it over.

Might have corrosion on the internal contacts of "Perko" or batt/isolator switch...happened to me...with everything off, rapidly spin that switch #1/All/#2 a few times by hand...cleans the internal corrosion off...then replace the switch if it works.

Not necessarily. GM starter solenoids do two things..engage the bendix and make a high current contact at the wire end. These contacts burn and wear. The solenoid can be sliding and engaging one but not both contacts. The old time cheap fix was to disassemble the solenoid and turn the contacts to a new surface.

If you applied 12 volts directly to the the small post on the the solenoid at the starter, and the engine started, that could indicate a bad slave solenoid, or possibly bad connections causing a voltage drop to the solenoid. Your slave solenoid could be clicking, indicating the electro magnet part is working, but the actual points of the switch could be burned, not passing the power to the solenoid at the starter. Get a voltmeter and when you have the key in the start position, check for 12v at the small terminal on the starter solenoid. If no power there, go back to the slave solenoid and check for 12v at the small terminal on it. If it has power, check the side of the switch that sends power to the starter solenoid, to make sure the actual contact points are closing and passing power thru.

Do like PBruce66 said, try your connections first. If it a clicking like a tick tick tick then I think you have a problem like PBruce 66 described. Take a wire brush to the connections even if they look good.

billinstuart - he went directly from the battery and bypassed, if he bypassed directlty to the starter it would just spin, if he connected directly to the solenoid the solenoid would still have to activate in order to pull in the bendix. In this case since the engine started the main solenoid is okay.
