Don't know of any 40 hp 2 cyl Merc's. Know that the old 4 cyl 44 cu in cross flow charged has been the 40 hp engine for the past 50 years. Remember back about that time they had a 35 that was 2 cyl direct charged.....was a blue band as I recall.<br /><br />Course what do I know? I dunno. Grin<br /><br />Must be something to that old engine. My latest catalog is '97 and that sucker (the old Marc 55 of the '50's ) is still there, still cross flow, still 2 carbs.....but it did get solid state ignition. People must like it which means they buy it. So Merc keeps selling it.<br /><br />Mark<br /><br />Mark

That should be a 1977 Mercury 2cyl 40hp

Hey AMD,<br /><br />I'm gonna bet that in '77 (or at least durnig that model year) Merc upgraded (had upgraded) the 35 to 40 and the engine I'm talking about was carried as a 50. Then later when they came out with the 3 cyl loopers they made a 50 hp 3 cyl looper and backed the old 4 cyl cross flow off to 40 hp.....or just changed the numbers on the cowling.....maybe smaller jets in the carb.<br /><br />What do you think?<br />Boy that has been a long time ago.<br /><br />Hey, you didn't answer me about your logo picture. Surely that isn't a picture of a 60 hp making a wake like that. 150 I'll believe. 60 naw.<br /><br />Mark

Actually I did answer your previous comment: Have a peek here:<br /><br />Thats 2 cylinder 40 was made for many, many years. Not sure when the powerhead rating vs. prop rating occured.
