Zip Engine in Need of Starter

Postby gdcarpenter » Sun Feb 05, 2012 11:49 am

Finally got the '59 Mercury Mark 35A mounted to the Zip, and despite putting the engine in our living room years ago after restoring it I now seem to have a bad starter.

For what it's worth its a Delco Remy Model # 1113553 Serial # 46749, 58 tooth flywheel and 11 Tooth starter pinion gear.

Solenoid checks out fine with essentially zero resistance or voltage drop accross it.
Triple checked all connections, both feed and return.
Disassembled starter and cleaned thoroughly
Using ohmeter tested commutator bars for short to armature - all clear there
Using ohmeter tested field winding for shorts to ground - all clear there
Short of accessing a 'growler' to test the armature I suspect an internally shorted armature.
Carbon brushes about 1/2" long but otherwise look acceptable.

Jumping battery pos. and neg. directly to starter still will not crank engine despite 'engaging' starter bendix, and fully charged battery voltage drops to below 9 votls.

With plugs removed starter will spin engine but definitely seems to be spinning it too slowly for 'free spinning'

So if anyone has a source for an starter I'd much appreciate it.
This is my first, last and only boat build.

Ebay or try a good auto electric company that specializes in rebuilding old starters and rewinding armatures and field coils.

Thanks Roberta, have researched local rewinding outfits and will contact tomorrow, plus have inquiries out with the 'ususal suspects' - at least time is on my side. Glad I decided to mount the engine just to triple check all connectivity, but do want to start her before removing engine to verify tachometer connection.

Hopefully be starting the top side sub deck very soon!

Here is one on EBay. Not sure of the number of teeth on the gear.
