help 6 horse johno impeller

ive got an old old 6 horse johnson [fisherman] outboard that i use on a 12 ft tinnie as a tender when camping .the old girl starts spitting steam instead of water arfter about ten minutes .hense i need to change the impeller and probably the pump housing itself .the problem is how do i get the leg off to expose the water pump .ive done several impellers on bigger legs which usualy means unclipping or pulling a pin of some sort to release the gear linkage .but with this old girl i cant even see the gear linkage rod as it seems to go straight into the motor itself.ive undone the gearbox prop end and can get it to drop about half an inch but am a bit scared to give it the old heave ho incase im busting something up the top .
any help would be magical .
cheers mitch

I know my 18 has an oval plate with 2 slotted screws half way up the leg which allows you to disconnect the shift shaft

The 15s/9.9s have a 3/8th bolt/screw that you can access when you put the gear shift to fowarrd and push down on the leg to engaging reverse, where the water pump is located

I'd br replacing the thermostat for good measure and with the leg off and thermostat out blow through the water intake tube and make sure the internal water passages are clear.
