Did you by any chance 'miss' totally in the connector for the upper and lower shiftrod?
Sure the locking screw got into the slot on lower rod?

its screwed in but i can see a gap in between the connection so the two shaft rods are not actually touching in the center of this connection and from memory i think one of the shafts are slightly corroded i could be mistaking this for the 15hp johnson i had

Take out the screw(s) completely and chec.
The rods should almost 'butt', and you should be able to see both ends in the middle slot.

ah that is most likely my problem right there when i look through the pivot pin screw hole i notice how much the cradle is off center i than remove the lower unit cover from the bottom and move the cradle back the same amount as when looking through the pivot screw hole than the cradle is around 2-3mm off of the forward gear its not a clean bond with forward gear

Re: is it worth repairing?

i went to a boat wreckers i mentioned above to pick up the new forward gear and clutch dog the owner of the shop removed the head assembly and found thick fishing line inside the inner head assembly stuck to the inner seal so thats one problem sorted the leaking he than looked at forward and reverse gears plus the clutch dog he said the gears looked ok and could still be used he said the clutch dog was worn alot on one side so i replaced that at the cost of $60 not bad considering the part cost double that from overseas and more than likely tripple that from a local johnson dealer so i purchased the clutch dog now im about to order the seals from a local shop as i want to be on the water this coming weekend so i looked at the ebay seals kit than looked up the johnson parts diagram web page and seen there were alot more seals i needed that we not included in the standard seals kit can someone give me a list of all seals needed please? and also with the main drive shaft seal how is this seal replaced is it a press fit do i need a special tool?

Go to:
http://www.boats.net
Use the Johnson/Evinrude parts lists, and you find all the seals etc you need.
Most of the seals you may probably get locally, just remember SST cup and spring!!
The outer prop shaft seal I think to remember is a bit special.
No special tools needed if a bit handy.
Note the depth the old seals are pressed into, and get the new back in same position.

Re: is it worth repairing?

ok i got a seal kit and i replaced the lower unit seals the seal for the shift rod was impossible to change i could not remove the brass bushing that was pressed into place so i jumped onto iboats done a search and read someone said to use a tooth pick to pick out the old seal and push in the new one well this worked a treat i thought i had pushed the seal all the way through and lost it somewhere in my shed lol but the seal was in place i than had a hard time removing the main drive shaft seal seems the metal used is pretty hard once the seal was removed i pressed the new seal into place using a socket the size of the seal and it worked i put everything back together i bolted on the lower unit before screwing on the lower unit lower cover i made sure to push the shift rod up into place and bolted the two shift shafts together with the clamp i than put the gears and shaft all back together i had to use my old clutch dog and old gears as the new clutch dog i had bought looked the same just the section the cradle slides into was a larger size so i had no option but to use the old stuff i than took the boat out not long ago down to the river i done around 3 miles loaded the boat back onto the trailer and came home i just drained a little oil out of the lower unit and it came out clear :) there were a couple drops of water but it wasnt mixed in to the oil so i think the water just came from the outside of the drain plug where it seals as it was about 30mins after removing the bot from the water i drained the oil so all in all it was a great success all up it has cost me $100 to buy the motor $60 in fuel to pick up the clutch dog than take it back $40 for a seal kit and another $40 in fuel driving to order and pick up the seal kit total $240 for a perfectly working motor what a bargain i now own a piece of history lol and the clutch dog didnt slip at all

Hopefully you may keep on being a happy boater!!:)
i always will have owned boats for the last 15 years there abouts my first boat was a small tinny with a 4hp motor lol i have to say i have owned a lot of boats and only 1 new motor and out of them all this 20hp johnson may be old but i think its one of the best motors i have had out of all the old motors ive owned it runs so smooth its unbelievable earlier this year i bought a new 18hp tohatsu and this 20hp johnson runs as smooth as the tohatsu all i need to do is fix the stiff throttle i tried greasing the pivot point without much luck i will also be adding a kill switch like the tohatsu has being a tiller steer and where i fish (around rocky head lands) last thing i want is to fall out and have the boat run over me :eek:

Yea, those 20's were based on the old 18hp design and are excellent motors. Simple to work on and incredibly dependable. It should last you for years:D

That all depends if it was imperial gallons or US gallons. ;);)
As long as it works, that is the most important. :)
