Propshaft alternator on 1985 Mango

Arlo
 

Hello all. Thought I would pass this info along to my fellow Mango and Maramu owners. (Not sure about the sharki or others)...Had my propshaft alternator rebuilt and a new regulator installed. The alternator is a motorola 9MR-2-814-0 20 amp 12 volt unit. The voltage regulator is not the original but we were able to get a motorola M5-763 regulator to work. Pictures are below.

As a Mango owner, I’m interested to know how you engage the alternator? Do you put the gearshift into forward or reverse while sailing? I understand there may be a difference depending on Model and year of the boat 
How much power do you generate when sailing?
Who did the rebuild for you?
Thanks for any insights you can share

 My Sharki from 1982 has a sticker near the gear shift level saying not to have the level in forward position and engine off while sailing.
Using the propshaft alternator the level must be in neutral position.
I have an instrument panel for the propshaft alternator with a switch key, an indicator lamp and an amp meter above the corridor to the aft cabine.
Depending the state of the battery the amp meter shows during sailing with about 6 knots 8 to 10 amps.
The propshaft alternator is a 40 Amps 12V Bosch type.
Rebuilding such an alternator does any good car repair shop for electric equippment.
The regulator is a cheap part you can buy at every car shop.
