If it has the old points system you will need to set the points also adjust the carburatior screw the screws all the way in and back out 2 1/2 turns then get it to run turn the air mixture screws till it runs smooth. you want it slightly lean then enrichen it slightly, afterword shut the engine down and look at the plugs if they are gray black they are ok. good luck.

I found a lower gear case assembly diagram at http://www.crowleymarine.com/mercury_parts/6995/240.cfm which helped me understand how the shift mechanism works. This clued me in to the fact that I was missing the cam follower rod which I then found I had inadvertently mopped up in a shop towel when cleaning up spilled gear oil. After that discovery, assembly and operation was quick and successful.

yam water pumps are clever the offste centre causes the pump vanes to flex during rotation and at low RPM you have a displacement type pump, at high RPM water pressure forces the vanes to flex inwards and the pump becomes centrifugal, you can fit the impellar either way up so you cant fit it wrongly make sure your gaskets are ok and that the delivery pipe to the power haed is not leaking (try a hose on it) also make sure the little woodruff key or on some models the pin through the drive shaft which turns the pump is fitted ok, not much else that can be wrong!
