Default Evinrude 100hp Cooling System Problem

Hey guys, okay ive just replaced the water pump, im positive the impellor is in the right way, positive that the water pipe is lined up correctly, and all my lines are clean b.c i am easily able to pass water through them with the hose. but when i start the motor i cant get water out the "piss hole". Really confused on this one hope you guys can help

Pull the hose off of the plastic water telltale outlet fitting, then clean it out with a piece of single strand wire.

If the engine's overheating, I'd suggest that you drop the lower unit to double check that pump. If water is flowing through the engine and it's just a case that water isn't flowing out to the telltale outlet..... have you checked that nylon elbow at the exhaust manifold plate?

That area..... the exhaust manifold plate assembly and the water telltale elbow outlet is the first place that water travels to.

You'll probably want to use some kind of gel sealant when you re-insert that nylon fitting.

Thanks to all you guys who tried to help me but none of that was the problem. I figured it out today. Liek i said i didnt know the year of my motor, so when i bought the new impeller kit, the plate that goes directly under the impeller didnt have a little inlet and the top of the water pump had an outlet that was supposed to go into it to get a good seal. well the new one that i bought was either older or newer than my motor and it didnt have the inlet on that plate so it wouldnt get a good seal and the water was getting pushed right out of there before it could even get into the motor.... at least most of it was because it only overheated on me once. Thanks alot guys hope this post helps someone else out
