What alternator for 1980 SKi Nautique ?

What alternator for 1980 SKi Nautique ?

After finally testing my old un regulated alternator it is official and she is burned out!

Where does one buy a new alternator for these beast? I don't know if my voltage regulator works and would prefer to get an internally regulated one. If so, which alternator do I get and how difficult is it to rewire?

Thanks again for all the help.

Good morning.

Thanks for your reply!

The auto shop said it was bad and I am not on the mood to dig into fixing this thing.
I like the one wire set up in that forum post you linked. However he does not list the part number of the alternator? I don't want to order something and then end up having to replace pullies or mount bushings. I searched IBoats, west marine, and Sierra marine catalogs and can't find an alternator that I know will work 100%!

I really want to get the alternator taken care of asap so I can work on getting my idle down (it's at 1200rpm) and possibly fix my timing issues (which may be part of the idle issue) I'll go into details of those in another post.

Thank you!
Would this be a good replacement?

I assume this is just two wires, ground and hot? Wouldn't ground through the mount?

Did you do some testing or did you take your alternator someplace? If the problem is a diode(s) in the alternators full wave rectification, that's an easy fix and I'd say the least expensive. If this is an option you may consider, the regulator needs checking too. You need to tell us more. I did a search for you on a one wire and came one with some information. One wire alternator Here's some info from Ebasic and a good source for a one wire.

I went ahead and ordered a one wire alternator from Ebasic! I'll post the model soon. I used a 4 gauge wire to go to the battery side of the solenoid. I roughly sanded the mounting flanges on the engine to make a good ground, I also added an 8 gauge ground wire from the alternator to the engine block.

It works great! My total cost was less than $170 and two hours of work max.

Thanks for all your help.
