Could be!? Check all to conections to the battery & starter motor and engine 'earths' too before condeming though.

Clean too?

Hi
Before condeming the starter motor, make sure that all connections especially earth wires are clean and tight. And no connections are getting hot/warm when cranking.
Also I would substitute the battery for a known good one to completly eliminate the battery from your diagnosis.

You say the battery is ok, has it been load tested and what does the voltage drop to when cranking??

[sophos9]

Battery at crank must produce >= 8v

i dont know what tests you have done on the battery but a battery will in time degrade,do you know how old the battery is? so even though it shows up at say 12-13v its the amps you should be concerned with, its possible you have a couple of bad cells,ideally disconnect it before checking due to other items drawing currant, you could try with jump leads off another car to see if more amps rectify the sluggish starter, or of course try another battery if you can find one to borrow, an iffy battery will always show up when the weather is cold & damp so id opt for that first as its easier than changing a starter,,,,good luck

right then when the engine is cranking over the reading is 11.6 is this about right

Quick elmination test - to make sure the earth cable is OK, connect a jump lead between the battery -ve terminal and a good metal part of the engine and try it again.  If it improves, check the earth connections thoroughly.

Do the battery terminals get warm when cranking?  If so, they're causing your problem.  You can also check my doing your voltage measurements in 2 places - battery terminal to battery terminal, and also the cable end to the cable end.  If there's ANY difference, your battery terminals are at fault..  Trying to take a measurement when cranking might be tricky - so try it just after you've started the engine (alternator should be producing some power at this point).
