    Hi Janice Parkin, I want to help you with your question, but I need more information from you. Can you please add details in the comment box?

    I cant find a 70hp range with your serial in. But 75's, Yes.
    You should have a sticker on the transom bracket. Upper is your serial, just below you'll find the year...

I have a 1995 mercury 3 cyl 90 hp outboard motor serial number 0G255422. The reverse has been woring normally but now the gears just grind when switching to reverse. The shift action is stiff.

Is the engine idling at normal speed? To fast an idle will cause this. If the transmission has its own fluid is it full and clean?

What year is my 75 hp mercury 4 cylinder serial number 0a986452

Locate the serial number plate by looking on your motor's transom bracket; the plate will have "Mercury Marine" written on the top. The serial number is the top number on the plate. The number directly beneath this is the year it was manufactured.
The year will be determined by the number of cylinders,,,
A 4 cyl. is a 1986 .
75 - 4 Cyl. 1986 ELPTO, ELO A197882 - B249479 = U.S. Serial Numbers A70708 = Canadian serial numbers
