1969 Johnson 20 hp shallow water drive

[thatone123]

I came across one of these 22 ci displacement outboards. What is amazing is the light weight of only 69 lb. In 1977 I understand they went to a bigger engine and lost the light weight of the motor. I have found this a great motor for a 12 ft Jon boat and the shallow water I travel in. Problem is it has no shallow water drive bracket like the 15 hp I usually use. Anyone have any idea if there is a way to get, make or cannibalize from another OMC to get the shallow water drive angle. Any good comments on this outboard would be appreciated. It seems to use more gas than the later model 15 even if only run half throttle.

Nope. Use a 2x4 or a similiar piece of wood

Find some 3/8" diameter bar stock.-------Bend as needed to get a u-shaped bracket that will snap into the tilt pin holes.-----Experiment with this to get the needed angle for shallow drive capability.

How in hell does anybody know what they wrote with tis new format ??????

 

[boobie]

how

raceone, yes, there already is one like that but it seems to only be for holding the outboard up high unless there is another way to use it. Also is there a outboard steering friction screw...looks to be one under the carb, but not sure it if is one.

A steering friction adjustment screw is going to be below the carb, but on the midsection, not inside the engine cowl.
That engine will be thurstier than the 15 hp introduced in 74, it is a bigger displacement engine, and it still likely dumped crankcase condensate overboard instead of recirculating all of it. It is an engine that was designed in the early 50s and had been around since the mid/late 50s, without many changes.
In 69 a version of it was hopped up to be a 25 hp. In 78 the 22 in block was only offered in Canada as a 20hp, and in 78 it too disappeared being replaced by the 32 in block introduced as a 35hp in 76 and 25hp in 77

That pin is the factory tilt pin. It can be used for shallow water drive.

Steering friction screw = hunker down and look just above the transom, between the clampscrews. See that screw looking back at you? That is the steering friction screw.

Way back in the 1960's A dealer that I knew had a box full of u-shaped brackets made.-----Put one on every motor that went out the door.-------A u-shaped bracket in addition to pieces already on the motor.----Could be used for trailering or shallow drive.----Used the open holes for the tilt pit!!----I have a bunch myself I think.

Outboard is an FD-21R Yes, I found that screw up under the motor in the back above the motor bracket. It is the same type as later models that have the friction screw on the side. This is after I tool off the kind of complicated carb, all for nothing. Oh well. I'll look at that bracket once more, seems it is too long for a shallow water draft device. Thanks
