Hi, I have a 1964 merc 500 that I have just replaced the impeller, as it was pumping but not that well.
Had no problem fitting the new impeller.
Double checked the timing and gave it a run on the muffs, it starts up OK but the idle speed seems to be up and down, it sounds like some cylinders are not firing and then pick up again.
I cannot see that it has anything to do with the impeller, but it was running better the week before.
Any thought's
