Alternator bolt Sheard

Recommended Posts

jdiaz78

Start my day off with an engine error...it showed a a misfire in cylinder number 8 again. After a quick inspection on the water, we could see a lot of water in the bilge. We were able to limp back to the slip. While trying to get the water out of the bilge, the alternator was leaning. A closer inspection of the alternator we observed a bolt was halfway out and broken. There was a second bolt that was holding the alternator in was tightened up.

I believe all the water that was in the bilge was caused from a rain storm two nights previous. I think the water might have caused the error because after it was drained and some running around, the error cleared itself.

Luckily I had someone on the boat that was mechanically inclined and was able to save the day. We had a day full of surfing and fun. The only item left is to remove the broken bolt and install a new one. I just hope that the broken piece of bolt will come out easily as I don't want to make a four hour trip to the dealer.

Shouldn't be a big deal to remove and replace that bolt. It happened to me on an older Sunsetter. I was able to get it out with an easy out and then cleaned the threads with a tap and I was good to go. Took about 15 minutes and the boat was 17 years old at the time.

Left hand drill bit first, and you may be able to skip the easy-out.

If you have the bolt size and threading needed, can you send it to me please? My boat is still at the marina and I forgot to grab the bolt to find a replacement with.

No recall.

OP, does your boat have a Marine Power engine?

I spoke with Gary at Marine Power and he is sending me a new bolt. He advised that the bolt he is sending is much stronger than the previous bolt as my engine has a lot of torque. Marine Power was easy to work with!

I thought it might be a MP motor.

Grade 8 bolts?

Grade 8 bolts?

Yes, Marine Power said that Malibu wanted the grade 9 bolt for aesthetics. He advised these bolts are breaking with all of the power from the engine. Once they go to the grade 8 bolt they haven't had that problem.

not sure why engine power would be particularly relevant.

I probably wrote it wrong, he was speaking about the torque put on the belts from quick acceleration of the engines. I am no mechanic, so I'm only probably getting half of what he said correct.

Grade 9? Maybe grade 5 or 2 ;)

I ask him to send all the bolts holding the thing to the engine and replace them all at once.

I'm thinking you were fed a line of BS.......

Exactly the same thing happened to my alternator on my '01 Sunsetter VLX this summer. It was a Grade 5 bolt that sheared. Had to drill down to get an easy-out on it. SLOW and precise is the key.

Mine broke on my ls3 also, I removed it by punching to Holea on the out edges of the bolt and using picks to spin it out.

I replaced mine with an equivalent ARP head bolt. It was a $15 bolt that I will never have to worry about again haha
