i just installed a sierra water pump and it started very iregular pumping so i tore it apart again only to find that the base plate under water pump the paint peeled off and was i guess plugging things up, so i put old johnson pump on and all was fine . also the new impeller from sierra was much thinner and origanal impeller this was for a 1980 johnson 15 horse j15rcsd
