Hi All,
I've got a service manual for my 74 25hp Johnson and was looking for the proper fluid to use in the lower unit. It says if you can't get Sea-Lube Gearcase Lube you should use Dexron transmission fluid!! Is this right?
Shocked,

Hi All,
I recently acquired a 1974 25 horse Johnson. Being an old Mercury guy for the last 20 years, I wasn't too discerning (dumb in other words) when it came to checking the motor out. It appears that the whole ignition system was changed out with an older vintage. Recoil, flywheel, coils...
I'm working on a 9.8 mercury and the throttle lever has broken. How do you set the lever correctly? It seems if you set it so the throttle plate closes all the way it won't open all the way. If you set it so it will open all the way, it won't close all the way.
Thanks for whatever you can...
The manual shows a rubber centrifugal slinger and an oil seal above the waterpump cover on the drive shaft for a 7.5hp SN 4135037. I don't recall the slinger ever being there...is it important? Where does it go, pushed down on top of the oil seal? The oil seal has always been there.
Thanks

I have a 7.5 HP Merc, s/n 4135037, that doesn't pump warter quite right. When you start it and let it idle, it spits water out intermittently with what appears to be exhaust gases. Throttle her up and you get a steady stream.<br /><br />I've changed the pump and am wondering if I have a leak...
I have a Merc 200 20HP, S/N 4410735 and I'm trying to identify the prop on it. It's 2 bladed and has 8087822 stamped on the outside. The leading 8 and 0 are rotated 90 degrees from the orientation of the 8782 in the middle as is the trailing 2. Any help would be appreciated.
