can you post a picture of the powerhead??
Sure can! I am the kinda guy that likes to know how things work. I am pretty sure it’s an 18 or 20hp. I was trying to understand the oiling system on this OMC powerhead. The gas/oil mix that gets pumped from the lower main bearing to the top bearing. I originally thought the drilling passages going to the reed block were blocked but they are not there on this engine. The older engines, I am sure you know, use the crankcase pressure to send lube through the motor. I might have to split the cases on this PH, to find out I guess! There is a line that goes from the transfer cover to the carb side of the reed valve that goes nowhere. The usual hose goes from the lower to the upper main bearing is there.
life is a puzzle! Outboards too!
Thanks dale
