Where do you find the model on 64 and earlier Merc 500 white motors. I see the serial number but not the model number.

Re: Merc 500 model?

Gerry, so it sounds like the model is determined by the s/n and noteally marked anywhere? The 61 is a short with starter. The l63 is a long with starter. Tring to fiure out if they should have alternators.

Here is the parts list for engines s/n 1421113 thru 1639472:

MERC 450/500 - Mercury, Mercruiser, Force, etc. Parts Lookup

See the stator, item 11 under FLYWHEEL ASSEMBLY AND STATOR and the rectifier, item 7, under STARTER MOTOR, STARTER SOLENOID, RECTIFIER AND WIRING HARNESS.

The rectifier is what converts AC to DC for charging your battery.

Don't know if you have a manual or not but the one you require is P/N: 90-25500 and here is one at an excellent price:

Mercury Outboard Marine Motor Factory Service Manual 1965 and Prior C 90 25500 | eBay

In the interim, here is a link to the condensed version of the Clymer manual to help you get started. Download it soonest to your computer as the link is short lived.
