Starter Alternatives

[ehlien]

I have a 1994 454 Mercruiser that cranks very slowly. Chances are I may have a bad starter. If I have to replace it I was wondering if there is a better alternative to the stock starter?? Anybody have any experience on this subject?

You could start with a new/rebuilt starter but it could also be :
bad battery cables
battery cable ends, internal battery cable corrosion
bad connection at the neg block connection corrosion or rust
corroded connection at the starter main post

The mini Perm Mag starters are not rebuildable. Cranking slow if the batteries and cables are good is not a good sign for the engine.

The starter is a rebuild that was put on in 2003. I have cleaned all the connections to the batteries and the starter solenoid, some of which did have at least some oxidization. Now I only have the main grounds to the motor left to do ( in a bit#ch of a spot to remove and clean) then I will retest but will be out of town a couple days.
