I have put the 150hp Evinrude on the V20 on the backburner for the moment.I'm now working on my Steigercraft Pilothouse.It has a 1990 Yamaha 200hp Precision blend motor on it.After some initial overheating problems I am working on the oiling system.I have changed out the strainer on the remote tank and cleaned out both oil tanks and added new oil.My question is how much oil should come out of the 6 lines that go into the block.Is it just drops or a steady flow? Does it increase if I give it throttle? I have run about 2 gallons of 50:1 mix through it so far to be safe after I cleaned the carbs.
 
You'll have to get a manual for the actual flow specs, but it isn't alot of oil flowing out. The manual will list a spec for flow from the pump at a certain RPM with it set to idle, and the pumps arm moved to wide open throttle.
