I got a 160 from a boat salvager. Looks to be in really good shape - just need a couple of items to try and run it before I put it in my "free boat". I need to get the cooling reconnected. I think the last owner was in the middle of replacing the riser/elbow but didn't quite finish. The riser is a bit rusted (maybe why he had it taken apart), so I'm going to use another one I have from a 165 (with a cracked block, hence the swap with the 160). With the "reverse flow" setup, there is a water hose from the thermostat that gets routed to the end cap on the manifold next to the riser/elbow. Then a line goes from the riser elbow back to the manifold end cap at the front of the engine. So the flow is "reverse" - from the thermostat via hose to the back of the engine, "reverse flow" through the manifold, out the end cap at the front via hose back to the riser/elbow.
This is where I want to make user I get it right. I'm assuming that the return hose to the riser gets connected with an elbow - 1"hose barb x 3/4 male NPT. The elbow would replace one of the 3/4" plugs on the side of the riser. Based on the length of the hoses on the 160, it looks like the hose connected to the top plug on the port side of the riser. But the Hose x NPT elbow is missing (I'm assuming the last owner misplaced it when he took apart the riser).
Does this sound right?
Evidently the "reverse flow" was an attempt to fix "hot spots" that develop in the manifold, but there aren't any detailed pictures that I've been able to find on the web on the exact connections.
