Re: test starter removed from motor

It might be a good idea to have it tested more formally at your local NAPA or AutoZone. That way you can see how many amps it is drawing. When the internals start to wear, it takes more amps from the battery to turn the starter. No load condition starter will draw 60 to 150A. On the flywheel they can draw 200-250A. Ensure that your battery cables are not cheapies (thick insulation and not enough wire), the battery is in good condition and connections are tight.

If the starter pulls way to many amps, then have it rebuilt or pick up a new one. It has to turn a typical V8 300-350 rpm to start the engine.

Replace with marine unit or have yours rebuilt locally.
