Japanese Mariner W-15 662

[egils]

Hi. I have a Japanese Mariner W-15 662 that needs a powerhead rebuilding. But I can't find any resources for parts or information on it. The serial number plate says 662 L 304833. A casting under the bottom cowling shows the Yamaha logo ( I know its built by Yamaha) and next to the logo is the number 650. Also the casting numbers on the pistons, conn.rods and cylinder assy all begin with 662, like 66201,66202 and 66203. Any suggestions?
Regards, Jon

Looks to be around a 1974 15 HP "Enduro" Yamaha motor according to the model/serial number. Best I can do right now. If looking for parts, look for Yamaha parts...Maybe others will have more info...Does it have the Gray/Orange paint scheme? I had a 74' 60 HP Mariner that looked like that...
