Cooked my impeller

[Jakem]

I have a mid to late 70s mc-1 outdrive as I've been told. Any suggestions on the impeller kit part numbers

Should be 46-96148A8

Ayuh,.... The MC-1 kits only come in 2 flavors,.....
Earlier has the little extra water port, 'n the later doesn't,.....

and the later one can replace the early one

Got it thank you

Installed new impeller and pump assembly and had great flow from back of boat...took boat out and it ran great...I did random heat checks with my ir gun. All was good....ran boat on muffs and I had more flow on port side and very little out the other. My manifold heat was climbing so I shut it off. Now while I was out running about 3000rpm I ran out of gas and boat stopped fast as you can imagine. Would that stop flow from leaving out the back on one side...like shutters stuck closed?

I also ran a wire up threw each hole on the back of transom plate and port side went way further then other
