Alternator advice - '85 Mercruiser 170

[spareparts]

make sure you have room for the alternator, not knowing how big your engine compartment is, but the alternator kits I've seen take up a lot of room in front of the engine and to the starboard side, if you don't have room, then the decision is easy. I haven't done a swap over in a long while, so I'm probably out of date on the offerings. I've got a 25 Bertram that I'm helping a friend with that has two 3.7L mercruiser v drives in it, we are going to swap out the charging system to alternators and use the area where a power steering pump would be to mount it

BTW, if anyone needs it, I have a brand new in the box 3.7L balancer for sale

Spare - how long before you decide what alternators you're going to use on your buddy's boat? I really want to get mine functioning, but would wait a little to see what you come up with.

If I buy a stator on ebay and find it's shorted to ground, or other problems when I get it am I likely to get my money back - not experienced with ebay. Also, would you be inclined to go with the $50 - 100 used ones or the $300+/- new ones?

ebay stators will probably not have any warranty unless it states different, even then it may be an issue as most companies won't give credit for returned electrical parts. If you go that route, look at ebasicpower, they have the stator on there for $219. Thats not much more than my cost. The 3.7s we are going to convert are a very different set up, with them being inboards, they have an unusual set up with a sea water pump and an odd engine bracket that prevents a normal conversion kit being used. We are going to have to come up with our own set up

On EBAY.... If the seller states that is is in good condition and you pay w PayPal then 99% of the time PayPal will refund you if it shows up "not as described". In that case you will get a shipping label to return it and when tracking shows it is returned you get a 100% refund including shipping costs.... The seller has nothing to say about it.

That said, I wouldn't waste my time installing used charging components that are just as old as the ones that failed... Once and done beats the heck out of doing it again next month.

Agree with Smoke, use new stuff with a warranty. Even then sometimes the new stuff doesn't work right out of the box.

[scook]

Yeah, I agree. It doesn't make sense to install something that's as old as what failed. Time to do the research on whether to go with replacing original parts or doing a conversion. Thanks
