Here’s a 5 hp Gale lower unit taken apart. The brown motor is a 1954 Buccaneer 3 hp,
and to the best of my recollection, it works the same way.
The first photo shows where the water comes up from the water pump rotor
and makes a 90 deg. turn into the space between driveshaft housing and tube
that bolts to the power head.
Second photo shows the notch and hole in the tube that has an internal passage up to
the power head.
Third photo shows where the water exits the tube and enters the power head.
(red "up" arrow)
The two red "down" arrows shows where water leaves the power head, goes under
the plate, and back into the tube.
The fourth photo shows the holes in the tube where water exits into the area
where the "slots" are, and blows out there, along with a little exhaust, I believe.
Hope yours is the same. If not, I’m clueless!
