1964 Mercury 85hp 850 Inline 6 - MFG runabout I think??

[Chinpoker]

Hello folk I'm new to this form and new to boat ownership I have in my possession a 1964 Mercury 85hp 850 inline 6 as far as I could figure out from the serial # 1662924 and an MFG boat, not to sure of the model or year previous owner said 72' can't find out anything about it I'll post a pic when I have 1!!

What I want help with is the fuel/oil mix ratio?
How to change the gear oil/grease?
What spark plug should I use?
Carb/fuel/water pump rebuild kit part #'s ?
How to properly start it up as I'm up here in the great white north any help would be greatly absorbed like a sponge
1 last question for now till I think of any more is what would happen if oil was not mixed with the fuel would it make it hard to start cause any engine damage ??? My dumb a** did just that and can't get it started now as easy as the first time I started it when I got the boat with the previous owner fuel in there before I found out I had to mix oil/fuel for it

Many Thanks on your knowledge
Dave

Yes, sadly you may have wiped the engine out by running it without oil and the engine especially if it doesn't have oil injection/ out of oil. I'm not fammiliar with the mix on that engine, but if I had to guess, I'd say 32:1 is a good guess, but it could be 50:1. At the very least it needs an inspection

Thanks I used sea foam in the mixed up fuel oil starts and runs fine! About the start didn't really run for more then 2 sec's without the oil I was just courious is there a specific way of starting these motor in warm/cold weather just turn the key,w/without choke , idler up half or nun
But what I would like help with is the parts part if anyone has owned or worked on one just so I can order and keep them on hand if or when I need them
Also what kind of prop? just to replace as I have no clue
And is repairing the skeg important to the driveability or just there to protect the prop?

Thanks again
Dave
