Hello, first of all I would like to introduce myself.
I am from Austria Europe and just bought a motor boat "Ilver Ecstasy 24" equipped with 2 OMC 165 HP engines from 1973.
The situation I have here is that one engine is missing the alternator and on the other engine the alternator is down, it's totally blocked and the housing is broken.
The type label on the original alternator mentions the part no. "Prestolite ALK 6210 3E" and it's a 12V, 34 AMP alternator. The OMC part no. of the alternator is 985964.
I have 3 wires comming from the original alternator and on top of the engine there is a BOSCH voltage regulator mounted.
On the internet I found an alternator which should replace the ALK 6210 or the OMC 985964 but the new alternator would be a 1 wire 10SI Replacement Alternator 1.
So I really don't know if I can buy this part and use it as it has only 2 connections instead of 3.
If I can buy it how will I have to connect it?
Thank you in advance for all ideas and help!
Attached I have added some picture showing the original alternator, the new replacement alternator and also the voltage regulator.
