How to get electricity out of manually startet 20HP?

[ghaffy]

Hello everyone in this forum. I find great what is going on here!!!<br />Although I was searching for a while I could not find anything about this so far (probably a typical newbie question):<br /><br />I own a 1981 Mariner 20HP and want to charge a small 12V battery. Is there any way to do this? Is it maybe possible to install an alternator or so?<br />(Mariner 20, Serial# 6A9-S-02260. built 1981)<br /><br />Thank you.<br />Regards<br />Ghaffy from Vienna, Austria (Europe)

They do make a Electric Start kit that sells for $342.00, but that may be more that you want to put out. 1 50-97693M ELECTRIC MOTOR $341.62 from here.<br /><br /> web page<br /><br />Look under ELECTRIC START MOTOR

thank you, Rick, for this quick reply. Infact the electric start kit seems to be nice, yet too expensive for me, and I actually need the power supply only, and not so much an electric starter.<br /><br />regards<br />Ghaffy

Usually "charging systems" are associated with electric starting. <br /><br />I looked at those parts listings and what jumps out at me is that thy use a different magneto assembly and flywheel for the electric start models than they do for the manual start ones.<br /><br />Looking at those prices and NLA staus of some parts, the best way to get a charging system on that motor would be to steal the flywheel and magneto stuff from a dead electric start model - then add the rectifier mounting plate and rectifier.<br /><br />-W

Excellent idea as usual, Clams. That would do it on the cheap. Check E-Bay for dead motors that may have thrown a piston or lower unit...

Thank you, Clams & Rick, for these ideas. I have now already contacted Marinerparts for what would be so to say the minimum package (maybe starter kit without start motor or so), and I am going through the ebay listings more or less world wide to find a dead Mariner or Mercury that could fit. If I read my parts & sevice manuals correctly, the 20/25/30 HP versions are pretty much the same in terms of the electrical system.<br /><br />regards<br />Ghaffy
