On EVERY Universal engine. EVERY ONE. The pump (facing it) turns CLOCKWISE, so it is easy to tell which hose barb the impeller SUCKS from (raw seawater from the thruhull) and which hose barb the impeller PUSHES through (to the Hx.)
**I have climbed the stupid tree and I own one in the backyard**!!
EDIT:
It DOES the reverse, the coolant pump SUCKS from the hose on the gear cover and pumps coolant TO the engine block and TO the Water Heater (via the hose barb on the of the freshwater coolant pump.)

EDIT:
Quote from: KeelsonGraham on Yesterday at 12:51:16 PMI've also confused myself by thinking erroneously that the raw water pump takes water from the HX.Also, many believe that the freshwater coolant pump "pumps" from the engine, TO the hose on the front of the gear cover.

You circled the seawater SUPPLY elbow (a 1/2" NPT elbow/inlet to the PUMP) and its hose barb is 5/8" ID HOSE.
If you follow the hose (easily done) you'll see that it DOES NOT go to the Hx - it comes from the 5/8" barb on the seawater thruhull (or strainer.)
The hose from the TOP hose elbow (which is also 1/2" NPT but 7/8" ID HOSE) goes to the Hx.
I previously posted resources on this forum showing the "B engine" hose routing and it is on the wiki:

Last post by KeelsonGraham - Yesterday at 12:51:16 PMThe other one definitely has a larger ID. So it looks like I have a 5/8ths inlet and a 7/8ths outlet. Catalina Direct doesn't list any 5/8ths hose at all, so maybe that's what's confusing me. EDIT yes it does, under raw water inlet hose.
Actually, I've also confused myself by thinking erroneously that the raw water pump takes water from the HX. Which, of course it doesn't! So that 5/8th pipe must come straight from the strainer, presumably?
I think I must have hit every branch of the stupid tree when I fell out of it.

Last post by Ron Hill - Yesterday at 12:40:29 PMKeel : 5/8" hose is both for the inlet and the outlet. I believe that you have the inlet hose circled!!
What I did was to move the inlet hose so it is under the outlet hose. That way you can change the drive belt without having to remove a hose from the Sherwood.!!

Last post by KeelsonGraham - Yesterday at 12:33:49 PMThanks guys. So, it sounds like the catalog part that CD shows is actually wrong?
Am I right that the 5/8th is the outlet from the pump?

Last post by Ron Hill - Yesterday at 12:31:31 PMCliff : The standard transom C34s have the propane bottle in a box that sets on a platform that's on top of the aft water tank. Not sure where the "sugar scoop" transom boats have their propane box?? The box is vented aft thru the transom.

Last post by Ron Hill - Yesterday at 12:25:58 PMKeel : 5/8" hose is what you need.
I don't know the routing of that hose to the raw water thru hull, but if your hose does NOT make any acute turns you do not need a wire reinforced hose and you can get a replacement hose at an auto parts store!! Heck of a lot cheaper!! $$
Why are you replacing that hose??

Last post by robbjd - Yesterday at 12:17:08 PMI think you need 5/8" hose. Your Sherwood pump has 1/2" ports.
