I have a 1984 Evinrude 2HP, it runs but requires choke all the time and gets very hot. I have no manual for this, how do i check that the cooling water is circulating and where do i get an exploded view to work out how to check the impeller etc?
You shouldn't attempt any repair without a service manual.You can find after market manuals here as well as a number of other places on the net. Sometimes at the library.
Runnung on choke indicates a poor fuel supply.Probably a rebuild of the carb with special attention to cleaning all passages and jets will solve the problem.If it has been awhile since it was run you should check the fuel system with special attention to cleaning.
Check the water inlet.If running in a barrel be sure the pump (in the bulge above the prop)Is under water.
Two bolts hold the gearcase on. The pump is in the bulge in the gearcase above the prop.
You might not need to rebuild the carb. All it may need is dismantling and coating in carb cleaner. All it takes is a tiny peice of sand to keep it from getting fuel. Agreed, you need to get a manual, and read it cover to cover. It isn't hard. I am 13, and have read the whole SELOC manual that covers Johnnyrudes 1.25 to 60 hp cover to cover.
bb1, i disagree, why waste time do it with a kit. that way you know you don't have any bad gaskets. if the impeller has never been replaced it's way past time to do it.

my 2 hp is a couple years older than yours, but I think it's identical. The cooling water comes out of the small holes at the back of the leg as a mist, or at higher rev's, a dribble. Mine was pumping some water, but I replaced the impeller anyway ('cause I don't think it'd ever been done), and it pumped quite a bit more afterwards, even though the original one "looked" fine.
On these motors, it's possible to have a fuel restriction at the fitting where the fuel shut off valve is attached to the tank, where the fuel line comes from. I think there is a screen in there to act as a filter.
Another issue can be poor fuel flow if you forget to open the gas cap vent. On mine, if the vent is only opened a turn or so, it will eventually vibrate closed and allow vacuum to build in the tank (and reduce fuel flow). Solution is to simply open the vent screw all the way open (until it won't open any more) then it doesn't vibrate closed.
Of course all this doesn't mean that you shouldn't clean or rebuild the carb and replace the impeller.... change the lower unit lube while you're at it. Also inspect the fuel line and replace if starting to crack, and check that the plastic clamps used on the ends of it aren't cracked / weak. Mine fell apart last season. You might also consider picking up a couple spare drive pins (also called "shear pins") while your at it. Either fasten them to the motor somewhere, or keep them in your tackle box. It would keep you from being stranded if you hit a log or something. Spare spark plug wouldn't hurt either.
