This would be typical of a replacement powerhead as you stated. The parts used from his original motor are painted.
The crankcase, heads, etc were pressure sealed in red primer before machining up through mid 80s. OMC didn’t paint their replacement P/Hs until they went black across the board. Different assy. process. The red primer process went away. If the dealer didn’t move the chip or paint the powerhead before installation it looks just like this. Lots of customers were not happy when this happened to their new engine.
Not making excuses, but think about it. Inventory of powerheads would have been a nightmare. You would have had to have copper colored ones (Johnson), blue (Evinrude), not sure about Gale, Sea Bee, or other makes. This would have been for all horsepower lines. It could change each year even if the powerhead didn’t? That was the reason they gave later on. When the P/H assy. went black, no problem.
The baffle is almost a matter of personal preference? I put them in. I never saw a SB that said take them out. If there is one I would be interested in seeing it.
