1957 Johnson AD-11 Sea Horse 7.5hp antique outboard AOMCI

Not much more can be said. It’s just another well made, easy to work on, great running OMC from the era when they were at their prime.

Nice motor! I have had a couple of those over the years. Nun of mine would go that fast. They do run sweet! Thanks for posting.

[@GearHeadJP]

You can’t go wrong with one of these 7.5’s!

[@fleetwin1]

Yeah, never were much for power or speed...

[@GearHeadJP]

They make it up with smoothness and quietness!

[@fleetwin1]

@@GearHeadJP true

[@curtchase3730]

Screamer! Sounded maxxed out. Can hear a little metalic knocking sounds when wide open.

[@GearHeadJP]

That’s the front face plate vibrating on the cowling.

[@fleetwin1]

Great engines indeed. But, they must be mixed at 16:1 because of the plain rod bearings. But, even at 16:1, they don't smoke much when in proper tune

[@GearHeadJP]

Agreed

[@RaidifyLifts]

if your a member of aomci do they require you to put that in the title of any outboard related RUclips video you make?

[@GearHeadJP]

No. I just try to promote the club any way I can.

Ok
