1947 sea king anti-tilt mechanism

[webrx]

Hi,

I have a 1947 5 hp sea king, runs great, thanks to the help I have recieved by reading through posts on this site.

I have one question though, there is a mechanism on the motor that looks like it should be a anti-tilt or possibly a travel position locking device, but it seems to be reversed (spring open) or I don't understand how to use it because I can't seem to get it to really do anything.

it springs into the down (open) position, has a couple grooves like it should be held in place by the positioning pin. Anyone have one of these motors that can describe to me how this is supposed to work.

Sorry if I am not being clear, but while being an old mechanic, I am fairly new to boating and outboards, I will answer any questions if you have em to try to get this figured out and any assitance would be appreciated.

I am hoping this somehow is used for locking the motor up while in transit, I just need to figure out how.

Thanks in advance

Dave

That is only to prevent the motor from trying to kick up when the motor is spun 180 degrees for reverse operation. If working properly it will prevent the motor trying to tilt itself out of the water for @ 2/3 of the complete 360 degree rotation. If it's not working you can only spin the motor to back up when at a very slow idle.

Thanks Tom, I don't think it is working properly as it does not seem to engage at all, but I will try spinning it 180 and see if it does anything.

There should be a thick sheet metal cam between the pivot bracket and the lower leg that is keyed to turn with the lower leg. It is the device that operates the anti-kickup lock---if it's working properly. I have seen more than one old Sea King on which the pressed in 'dimple' in the cam is worn to the point that it no longer pivots in company with the lower leg. My fix has been to have a heavy spot of weld put on the plate in place of the worn-out 'dimple' and ground to shape with my Dremel tool. Had to do that to my '47 3 horse Sea King last Summer in the restoration process and it worked just fine.
Motor runs like a champ too----WITHOUT having to chase any parts except for the cosmetic restoration bits. The old ignition systems prior to the advent of the OMC 'universal magneto' seem bulletproof. Pulling the mag plate and scrubbing away decades of grime and grunge, polishing and resetting points has worked for me on 3 Gale/Sea Kings to date whereas I ALWAYS assume the coils will have to be replaced on a 'universal magneto' later model! HTH, Tom

Thanks, I will check it out when I get a chance. My old sea king ran when I bought it, I did put new spark plugs in it, learn how to tweak the mixture, and replace the pull rope - couldn't find one with the braided cable innards, but a standard cotton pull rope seems to be holding up so far.
