Hi, I have a Mariner 3.5 hp outboard. I'm trying to find out what year it is. The serial # is 642S 30987. The owners manual has what I assume to be a print date of 7-1-1976. Does this year sound right for the motor? Also, I though this outboard was made by Yammaha. Any thoughts? Thanks, Doug

My book of serial numbers (genuine Merc book) lists it as 1974-1980.. The reason for the range is covered by the following statement, made by Mercury about the earlier Yam-Mariners....

"Mariner engines produced from 1974 thru 1987 did not carry a model year designation. Mariner dealers were directed to sell Mariner engines by feature rather than by model year. Engines produced in one year and sold the next year were considered current engines of the year sold. This applies to all 1987 and prior models and serial numbers listed in this report regardless of where the engine was produced."

Yes, they were made by Yamaha, and badged 'Mariner'.

HTH,

Chris..........
