Hi <br />I have what I am told be a 1986 Mariner 55el It says that on the engine cover and data plate with serial # 663 L 317554<br />I cant find any workshop manual or info on this motor.<br />Though Clymer print a manual 2-220 1976-1989 there is no mention of this model.<br />Clymer have ignored my email request for help. Is this expected from this company?<br />Hope someone can help.<br />Regards to all, David
<br /><br />That's made by Yamaha. A Yamaha manual would be appropriate.
