Engine won't crank. Batter

Engine won't crank. Battery is above 70% charge. I disconnected the starter motor from the solenoid and turned the start key;the solenoid makes a solid click. With starter motor connected the starter rotates and then stops.It never gets sufficient RPM to throw out the gear to engage the flywheel. Suggestions? Do I need more tests to make sure it's the starter motor ?

I don't understand the slow starter motor rotation. Does this sound like I might need a new starter motor or does it sound like I could repair it with a repair kit?

"All cable connections must be clean and tight, remove, clean, then retighten all of them, including the battery terminals, powerhead ground, etc.

Using a good known battery, fully charged, run known good jumper cables directly to the electric starter. If the starter cranks the engine normally, then obviously the starter is okay.

This will happen with a weak battery. You can charge the batt until it reads full charge but there is not sufficient amp's to get the gear to pop up to the flywheel. Try a different new batt before spending money on a starter rebuild. Starters are geared to seem slow turning but the flywheel to starter ratio is correct.

"I had previously cleaned and tightened all battery connections. Nevertheless the starter switch behaved intermittently. Sometimes I'd get the beep when turning the key switch on, other times nothing.
I therefore checked all pertinent connections with a voltmeter. I found the problem in the attachment of the positive cable to the battery post. It seems the wing nut used to hold down the cable end loosens and is unreliable. It is a stamped and formed wing nut. I am going to replace it with something more substantial.
Everything is working fine!
Thanks to all for your suggestions."

And that's why I included the battery terminals.

Wing nuts! Replace them with a proper size nut that you can tighten with a wrench.

"Joe
You were right about checking the battery terminals. As for the wing nuts, as far as I can see any marine battery terminals sold these days with vertical posts come with wing nuts. I can certainly tighten a well made wing nut with some leverage from a wrench or pliers, but I'm wondering if there is some kind of lock washer
which would work for the corrosive conditions in this application."

"Yes, the wing nuts if high quality, tightened with pliers will work fine BUT most boaters give in to temptation and use the finger/thumb method on those things."
