Just both this outboard and was out with it and at top end it seamed like the motor propeller just stopped turning slowed down and it was fine but did it again so took it home just wandering where to start to see what is wrong ? would there be a bad gear in side ?
 
i just took the propeller of it looks good no sign of any damage does not look like its slipping
now i think this is a 1967 super sea horse 40 electramatic any more ideas?
 
Oh, okay..... I had just assumed that the engine was a later thru hub exhaust model. However, you say that it is a electric shift model which brings up another type problem.

BTW, it's unlikely that you would see evidence of a slipping hub in a propeller just by looking at it. You can make a mark on the hub and also on the prop, having the two aligned, then run the engine. After the problem surfaces, inspect those two marks. If they are no longer aligned, the hub is slipping.

Having said that..... Those old electric shift models were notorious for having the shifting hub slip within the torque spring within the lower unit. These two items are very expensive articles if you can find them.

Make sure that you do have a full 12 volts being applied to the lower unit (green/forward) shift wire.

Check the lower unit for gearlube. Make sure that it is full of the proper lube which is "Premium Blend" also known as "Type C", available at any Evinrude/Johnson dealership.

With the gearcase full of the proper gearlube, and with a known good propeller, if the unit still slips, you are then unfortunately faced with a lower unit repair or replacement job.

ok thank you and i will check out the power and i have already removed the lube from the lower end and went to the dealer and both new lube i will fill it mark the propeller and go for another run see how it goes thank you
 
Slipping hubs on alectramatics are easy to repair.------------You need to find a shop that " knows how to do this simple procedure "--------------You must have a belt driven generator to keep the shift system working properly.
