Hello,
I have a 1984 Evenrude E2RCRS 2 HP 2 stroke outboard motor. The engine has sat for the last 3 to 5 years (I also think it was run in salt water) but I got it running and runs well except when I run it no water comes out of the four holes on the midsection of the shaft ( I dont know the correct term) anyway I can see that drops are shooting out of it as well as air. I have two questions do i need a new impeller (or is it clogged) and does the impeller cool this little two stroke engine. I would imagine it has to but cant figure out the route the water would travel from the schematics I have been looking at. Hope someone can help!

Has it seen salt water yes it is possible especially if it has been stored laying down allways store it in the running position. If the impeller housing is pitted or have grooves there is a cup you insert into the housing as an upgrade. If the impeller is all chewed/broken up there may be chunks up in the head. Once you replace the impeller put it in a barrel of water and pour a gallon of bleach in and let it run for a couple of hours see if you get plenty of water out the four holes.

ok so i took it apart the impeller looks good but does not make complete contact with the dge when it is totaly exteneded. so i took it off laid it in the sun and pulled the fins the opposite way to stretch them out. i'll see if that works for a quick fix. i will order a new impeller tho. the wall doesnt look pitted and is smooth. one question tho, when i put the impeller back in what way are the fins suppose to go? i took it out without noting what direction it was facing (bad move : ( on my part). if the impeller fins look like a wave the the back of the wave should be the leading edge i would think.
does the bleach remove just parts of the rubber impeller or will it unclogg corroision in the cooling system? thanks for all your help so far.
 
On a new impeller the fins would be straight.----------Obviously if fins do not contact the outside edge the impeller is old and has taken a " set "- and it is junk.---Do not run the motor with it !
 
In agreement with Racerone... replace that impeller.

Also... sitting for that length of time, order a carburetor kit and clean the carburetor while you're at it.

(Carburetor Adjustments - Two Adjustable N/Vs)
(J. Reeves)

Initial settings are: Bottom high speed = seat gently, then open 1 turn out. Top slow speed = seat gently, then open 1-1/2 turns.

Setting the high and low needle valves properly:

NOTE: For engines that DO NOT have a shift selection, obviously there is no NEUTRAL position. Simply lower the rpms to the lowest setting to obtain the low speed needle valve adjustment.

(High Speed) Start engine (it will run pretty rough), shift into forward gear, take up to full throttle. In segments of 1/8 turn, waiting for the engine to respond between turns, start turning in the bottom high speed needle valve. You'll reach a point whereas the engine will either start to die out or spit back (sounds like a mild backfire). At that point, back out the needle valve 1/4 turn. Within that 1/4 turn, you'll find the smoothest setting.

(Low Speed) Slow the engine down to where it just stays running. Shift into neutral. Again in segments of 1/8 turns, start to turn the top needle valve in. Wait a few seconds for the engine to respond. As you turn the valve in, the rpms will increase. Lower the rpms again to where the engine will just stay running. Eventually you'll hit the point where the engine wants to die out or it will spit back. Again, at that point, back out the valve 1/4 turn. Within that 1/4 turn, you'll find the smoothest slow speed setting.

When you have finished the above adjustments, you will have no reason to move them again unless the carburetor fouls/gums up from sitting, in which case you would be required to remove, clean, and rebuild the carburetor anyway.
 
thanks for all the info guys. trying to bend the fins back out didnt work. but i do have a new impeller on order. i ran the motor for less than five minutes at a time without the impeller and only at full speed for about 20 seconds. doubt this would be enough to heat the rings and cylinder too much.
again thank you.

Did this do the trick for you? I just picked up the same motor and it has the exact same problem as yours. I just got to the impeller and it appears to be in great shape.
