Where do I release the tension to get the raw water impeller out, first time doing it.

I don't have that engine...but I would expect it is similar to the 5.7

Thanks AirTool, so from what I've read, turning the nut/bolt clockwise will loosen the pully and then the opposite when I'm done to tighten it back up?

That pulley is bolted to an arm that is tensioned by a spring. You don't want to loosen the bolt, just loosen the tension on the belt being placed on it by the pulley and the belt will fall off. Make a mental note of the routing of the belt before you remove it.

"just loosen the tension on the belt being placed on it by the pulley and the belt will fall off."

Confusing statement. I am asking how to loosen tension. I didnt see an obvious spring or release of the arm.

just go clockwise easy, you should see the pulley move. If not, go the other way. I can't tell yours by looking but mine was clockwise - you can see in the picture.

Its the only pulley with a visible nut on it, take a 5/8 wrench and yes turn it clockwise. it will spring back up with no belt on it, so be careful, Ive smashed a few fingers just letting the wrench go. Do the same to re-install the new belt!

In the 2nd Picture it will be the top right (port) pulley.
