VW Pathfinder 50 marine diesel questions

[Sv_Veela]

Hi all I'm looking to replace the alternator on my pathfinder 50 but don't have a part number to reference, does anyone have specs on it. Currently have a 100 amp with balmar regulator

The original service manual states the Pathfinder engine had a Bosch alternator and could be driven with one belt if the alternator was 90A or less. A specific alternator is not mentioned.
Mine has a 75A Balmar alternator which was recently rebuilt. I'd like to find someone who'd like to buy the whole engine so I'm reluctant to start selling parts from it.

Thank you I had a 100 amp and it was burning belts even with balmar regulator. How much are you looking to get for the whole engine and where are you located. I am debating a repower in my boat.

This is where I'd like to take the conversation off this public forum onto my private email.
If you would reply to thibodeaulen29@gmail.com I can answer your question and provide more information.
Thanks
Len

I spoke to a parts person at Parts Place Inc. in Michigan who said that even they do not have a copy of this rare manual!

If there is anyone in the world who has this manual, they would be doing a number of us a great service by having it scanned and posting a digital version to the manuals section on the Cruisers Forum. I'd be happy to cover the cost of having the manual scanned by a commercial operation (many print shops provide bulk scanning services).

I don't have that specific manual but I have a Owners manual that includes a parts list and VW equivalents

We repowered last winter so I don't have the engine anymore, but I do have the manuals for the Pathfinder model 50 engine and Hurth HBW transmission. Photos should be attached. You can have both for $100 plus shipping.
I believe the Hurth reduction ratio was 2.7
