I am a new owner of a 1988 Bay
I am a new owner of a 1988 Bayliner with twin 5.7L w/ omc outdrives. The port outdrive keeps chewing up the impeller. I have replaced the impeller twice after running for only 1 hour each time. I replaced the entire waterpump assembly the first time and just the impeller the second. Is any additional lubricant required for these impellers or are they just cooled/lubed by the water passing thru.
I did take the entire waterpump assembly off and briefly start the engine to see if any debris came out and some did. After a few seconds no further debris came out.
Any suggestions?
