Alternator Replacement - 350 MAG

YYZRC

I pulled the seawater pumps today (what a nightmare of a task - especially with SeaCore) and while I had the belts off I gave the alternators a spin.  One clearly needs new bearings.  Thoughts on having the alternator rebuilt vs buying new aftermarket?  Looks like an aftermarket alternator is around $100 and I expect rebuilding wouldn't be much cheaper.

Thank you.

That's a marine alternator? I'd be sure to get the right one...no spark s allowed!

I'm betting a Marine alternator is more than double that price.  That is definitely NOT a part you want to try not using Marine.

Lots for under $100.

Just keep in mind that is not an oem mercruiser part, it’s just an offset for mercruiser, brand is “discount marine” or whatever. I always stuck with oem or Sierra for mercruiser parts. How much is a Sierra alternator?

DB electrical has good prices on marine alternators and starters.  Call them with your serial number to make sure you get the right one.  1 yr warranty i believe. Located in Tennessee. 

My dad has their starter and alternator on his pontoon and has had no issues.  3.0 inboard i believe.

That's my only experience with them.

Id still have the old one rebuit for a good spare on the shelf.

That’s exactly my plan! I will roll the dice on the aftermarket part, I’m sure it will be fine.

@skennelly , I just checked DB electrical’s site, great prices if they have quality products.

Being that there is a real person that answers when you call at a real facility there's usually a good chance the products are quailty.   If they were prone to issues with their warranty it would be a constant headache.  Unlike ebay/amazon where you're billing statement is in Chinese and the seller is pushing items they have never inventoried.

I replaced both of mine with ones from DB Electrical over two years ago.  I held onto one of my old ones as a spare.  So far they have been great.

I had a local guy rebuild my starter...not sure if he is still around or not as that was 5 years ago...guess he did a good job!
