trying to ID my engine

[vaporvette]

I have an older 35 h.p. mercury. The only numbers I have gotten off it was from a sticker on the transom clamp assembly. The # is 0A966312.
I don't know if this is a short or long shaft.I'm not even sure if it uses premix fuel or not
I am trying to locate the proper manual so I can work on it,any suggestions as to the best one would be appreciated.

Anyone have any guesses as to the model year and fuel type? Can anyone recommend literature for me to figure it out myself? Thanks

It's a 1986 35 ELO which stands E= Electric Start, L= Long Shaft (20") O= oil injection.

The oil injection mixes the oil and gas, assuming it's still hooked up and being used. Many have disconnected the oil injection and went to premix.
If still in use, you would have the Auto blend system (not on the engine) that has an oil tank and oil pump.

Looks like this. http://www.ebay.com/itm/Mercury-aut...pump-13019-3-boat-/320570716438#ht_500wt_1180

That was very helpful,Thank you. The injector is long gone,what oil/fuel ratio do you recommend?
