Need to identify this motor, can't find anything on internet to match. The serial # on motor is OB179717, I can't get definite info on internet. I can't get it to pump water out of tattle tell so looking to get a new water pump.
 
Numbers are sketchy for the mid eighties, that number is an '86. Have you pumped air or poked the tell tale with a bit of wire? Regardless of it letting water through, if this motor is new to you, change the impeller anyway.
 
I did run a wire through it plus blew air also. Lines were clear. Put it in lake yesterday and it did pump water but took a minute or so to catch a prime. Was blowing steam until prime was caught. Did good until motor was stopped. Started back up and it did same thing. Found a retired mercury mechanic who will take a look at it. Thanks for the reply
