Make sure the impeller blades are oriented properly (engine turns clockwise looking at it from the top). Don't forget the key that locks the impeller to the driveshaft.

On bigger motors, a ratchet strap over the top of the cowling will help hold the lower unit as you get it aligned and reconnected when you go to put it back together.

It scared me until I figured out that the cooling water is routed through the exhaust on mine. No pee hole connection. I think I'm still gonna have my shade tree change the impeller when he hauls it in a couple weeks to install a fish finder.

The driveshaft always rotates clockwise looking from the top.

Ratchet strap is a rookie thing.

I can't count the number of large V6 gearcases I've stabbed by myself. Doing one on the back of a houseboat, in the water,

is really fun!
