While trying to start my 3.7 170 hp yesterday I could not get the motor to turn over. I used a fresh battery with 650 cranking amps. The crank turned maybe 1/8 of a rotation during the whole day-30 to 40 starting attemps.The oil was full and clean. 2 months ago it ran perfectly. I removed the plugs to relieve compression no differance. I loosened the year old starter hopeing the bendix gear was jamed but it was not. I then removed starter checked on bench seemed operate fine. Teeth on flywheel OK.Sprayed WD-40 into cylinders. Tried to turn with 3/8" rachet on crankshaft bolt would not budge. Closed system fluids were normal. I used 3 different batteries all were good. Is it possible something in the outdrive was preventing turn over? The oil was drained in the lower unit because I was getting ready to change the water pump. This has me stumped due to the fact that was operating so well just 2 mos ago.
