wont crank

[gone_fishin14]

I recently bought a 72 fiber form with a 351w stern drive merccruiser model 888 I noticed yesterday a crack on the water intake at the top of the engine on the left side above the exhaust manifold I tryed to star it and it tryed to crank(cranked really slow about 1 full revolution)and it wont crank at all now.it just click I checked the batt and it has full charge any sudgestions.

p.s.I tryed to turn the block with a breaker(no luck) bar but wasnt sure of direction

Re: wont crank

Remove all the spark plugs, then try cranking the engine.

Re: wont crank

You didn't drain all the water out of the block last fall, didja? It froze and cracked!

There's a good chance you bent something by cranking on it without knowing what was wrong. Water could have entered a cylinder from the crack. Your piston rod will bend before you compress a cylinder full of water.
