I just machined down a new impeller to fit and it does pump water (I put the lower unit in a pail of water and turned the drive shaft with a drill) the water jackets are not plugged as I ran water from a hose into the water intake tube while the lower unit was off. test ran it in a garbage pail full of water after assembly didnt pee. there is a water flush hole on the back of the leg if I take the screw out I can spray water in there, comes out hole on front of leg. but when running nothing comes out there. I think exhaust gasses exit behind water intake just above the prop, is that where cooling water comes out as well? I just got a service manual but it dosent have this info.
Thanks
