I have a 1995 Merc. 175 EFI - coming in today it made a grinding type noise and stopped, no alarms. The flywheel will rotate back almost a full turn but forward it hits a solid stop. Any ideas???

Sounds like it broke a rod, pull the spark plugs and make sure the all pistons are moving.

Thanks laddies, I'll have a look at it when I get home Sat. Ever hear of something jamming up in the lower unit.

Yes, quite often a pinion brg. will set a engine up, the differance is your turns back and forth till it hits something (probably the broken rod) and you can turn it back a half turn till it hits it again.
