" My 1979 OMC 800 is losing prime at the impellor pump. The telltale will flow and gradually stop. No water out the hose to the motor water pump. Replaced impellor, housing, wear plate, and all associated gaskets and seals related in the mid and the lower unit. Dealer indicated to run rtv around the top and bottom of the impellor housing outside to keep from sucking air. Any ideas??? Nothing has helped. Thanks. Rick "
