6.2L Merc with starter issue
 

First let me say that I have read the sticky thread on starter issues. But let me give you some background...

I just bought this boat a little over a month ago. We ran it 4 times in fresh water and no issues whatsoever. The last time we took it out, it started overheating as soon as we left the dock. I immediatley turned back around and shut her down. Once I got her home, I realized that the impeller had disintegrated. There was nothing left but the rubber shaft! So I replaced the impeller and the whole water pump housing. I wasn't able to test run her on land because my intake is on the bottom of the hull and I can't get a flusher under my trailer. So I took her back out to the lake to see if the impeller worked. When I turned the key, I got a very loud almost metal sounding bang, and the engine did not turn. I freaked out and thought the engine had seized up. So I took it to someone who looked at it and hit something back by the starter and the engine did bump over a little. We found that terminal A on the starter solenoid had disintegrated and the rubber boot over it was melted. I replaced the connector and tried to bump the engine and get nothing now. No click or anything.

So this is what I get following the sticky starter thread: I get voltage on Terminal A of the slave solenoid with the ignition switch off. As soon as I put the key in Accessory position, the voltage disappeared. I got no voltage on A, B, C, or D of the slave solenoid. UUUGGGGGHHHHH

I have tried to remove the ground wires on the grounding buss bar to clean them but they are frozen on there! So I am soaking them overnight in JB Blaster and will try tomorrow to remove and clean them. I am just hoping that after all this that my engine will actually crank and isn't toast!!!

Anyways, any help would be greatly appreciated....

I am such a freakin' idiot. After cleaning the ground buss bar in the engine compartment there was still no change. Long story short...It turned out to be a dirty terminal on the ignition switch. I cleaned them all up and the engine bumped over! Yea! Now I just need to get my Flush Pro system so I can start her all the way up on land.

Very glad to hear the good news.

Re: 6.2L Merc with starter issue
 

The saga continues...So I installed my homemade flush valve( I didn't want to fork out $68 for the Flush Pro system) on my raw water intake today and was so excited to try and fully start her up on land. So when I turned the key it sounded like the engine was turning over, but it was a loud metal sound. It was like the starter wasn't grabbing. So I am assuming that my starter or flywheel is shot. Is this a correct assumption? I will pull the starter tomorrow and see what it looks like. And any tricks to pulling the starter?

Re: 6.2L Merc with starter issue
 

Just a note, make sure voltage is high on the batteries. Its possible for the starter to not operate correctly with insufficient voltage I believe.

Re: 6.2L Merc with starter issue
 

Yea, my batteries are fully charged. I keep it plugged into my trickle charger with shore power at my house. Is there a way to check the flywheel when I pull the starter? I hate to destroy a new starter because it turns out the flywheel is chewed up!

Re: 6.2L Merc with starter issue
 

Maybe also check if not in gear whilst starting.

Succes,

Ok, got the starter out. I posted some pics of it. Is it possible to rebuild this or should I just chunk out the $214 for a new one....:(

Re: 6.2L Merc with starter issue
 

I vote go new, I am all for saving a buck but not on the starter. And only buy the marine starter, they are not the same as auto parts starters as you are likely aware.

Brand new starter installed and she fired right up! Love it!!!
