I just replaced the Impeller on my omc 400 stringer outdrive. I might have not sealed it up right.
I haven't got my manual yet so I can someone verify where I need to put the permatex?
Also, which way do the vanes on the Impeller which way are they supposed to face. I have the 4 bolts on the bottom on the bottom off so it would be looking up into the housing.

How do I flush my manifolds? Can I just take them off and rinse them? There might be a blockage of some sort in there.

Im guessing the problem is in my outdrive though. I had the hose adaptor hooked up and it ran great idling in the yard. I took it out and after about 10mins it starts to get really hot. Didn't want to chance it so I shut it down and waited til it cooled down a bit started it up and headed for the ramp. Please help.
