quote Jerry Ahrens:
Some of the earlier Mercs used the inline oil injection unit that sat inside the boat. It was inline with the boat fuel line. Was that called Accu Mix?? or maybe Econo Mix?? something like that anyway. I don’t know if that engine would have used that type system or not. Bill will probably know.. this was a completely self contained unit that injected the oil into the fuel stream as it passed thru before it got to the motor. I remember a Mercury instructor saying to throw these away, and to get rid of them, if one ever came into the shop. Evidently they had problems.
I seem to recall it being called "Auto Blend" and our instructor telling us the same thing…ding ’em. I don’t know if they were ever used with Yamaha built Mariners. I never saw one in that application; but there is plenty I haven’t seen.
Clearly the one in this thread must have been available either way…premix like it is currently or actual Yamaha injection, as evidenced by the under cowl tank in my earlier link to ebay.
Long live American manufacturing!
