Old motor. I'm sure it has an impellar. The reason you are having problems with info IS Spelling. It is a Kiekhaefer. NOT kiekhaeter. need serial Number also. Than Go To.
oldmercs.com. Guessing about 1950?
thanks for the heads up on my miss print. The serial number is 425761 and it appears to be a 51. I have been to the oldmercs site but cannot find any repair manuals. I was hoping somone owns or has worked on this paticular motor.
Your gonna have a hard time finding that manual. You might try E-bay. Its actually not a difficult motor to learn. Just take your time and write things down when you work on it.
It DOES have a waterpump. It is located at the seam between the exhaust housing and the gearfoot. A manual is a must - oldmercs.com has them, referred to as the 1965 and prior manual. It covers all pre 1965 Mercs... You can find them on eBay from time to time, too for cheaper...
