I need to reseal the Crankcase halves on my 1981 75hp Evinrude, I pulled the power head off and I am ready to separate the two halves but before I remove the bolts to separate the halves I was curious if the power head had to be in any certain position, I have the power head sitting on my work bench in the same position as it would be when it is mounted to the leg on the boat, is it ok to separate the halves in this position? I know to some this may sound like a stupid question but I just want to be sure that the crankshaft won't drop down or out pulling the pistons down to low.
My manual doesn?t say any thing about what position the power head should be in but it does give detailed instructions on how to separate the halves.

Re: Resealing Crankcase Halves

Lay it down on its back and remove the front half. From there you can rotate the crank as needed to get to the rod bolts. Much more stable than trying to work on one in the upright position.
