Here is a website where a manual for you outboard may be purchased.  Outboard Marine went out of buisness in 2000 and thus no parts of origial manufacture are support is available . Therir are secondary markets .    THe Lower case splits in half and their is a seal around the prop shiftm which is pressed in. The seal between the cases are cut o-rings which are placed and glued into place with gasket seal.
The water pump is located where the case splits a little bit higher. You must open the little port on the side and take out one of the screws to the connecting shift linkage to split the case. After splitting the case the drive shaft and water pickup tube(s) wil come out of the powwer head or the tubs may stick into the power head which is ok. Place the lower skag into a vice and remove the 4 or 5 screws to the water pump housing. Remove and replace impellor and impellor plate if available. If part(pieces) of the rubber impellor is missing flush out the tubes and the power head to remove them.   When reinstalling the lower unit use a flash light to make sure that the tubes return  to the proper place in the power head and the shift lever is resecured. If you need more assistance, just write back. I was an Outboard motor mechanic for five years about the time of your motor.

Sound like the fuel pump is not keeping up with the engine's demand. Check it out. Good luck. Hope this helps.

SOURCE: Missing operators manual for Evinrude 2 hp outboard motor

Your best bet is ebay for a replacement user manual. Take a look around, you will come across one... For the meantime, gas oil ratio should be 50 parts gas to 1 part oil, i.e. 50:1. General care: Dont go full throttle for any length of time. Cruise of 3/4 throttle... Always flush engine after use in saltwater, including washing down exterior. Keep spark plugs in good order and check prop for fishing line wrapped around in near the prop hub. Otherwise, get a yearly service and have them check the water pump and replace as needed, get it tuned etc and gearbox oil changed.
