Re: m70a2 impeller

You are not pumping. The "air" is exhaust leaking back into the cooling system. You may not have the water pump aligned with the water pipe. If so, even with the pump working, it would be pumping into the exhaust housing, rather than up the water pipe.

You need to connect wp housing upper rubber round seal into water pipe, probably misaligned during lower unit back up. Pull leg down and align properly when assembling back.

When I dropped the LU there was no water pipe attached to the impeller housing unless it came off when I was removing the lower unit. And is stuck in the housing is this possible
