My '63 Merc 110 9.8 HP, has been running great. Yesterday while out on a cruise around the lake in my 1956 Alumacraft 14 footer, I noticed very little water coming out of the Merc 110 exhaust at idle, and little to none at cruise. I stopped immediately and opened up the hood and put my calibrated hand and the head, block, and spark plugs. I was surprised and pleased to find that the were only very warm but not at all hot to the touch after a good hour or so of running at different speeds. I was was about 3 miles from my boat trailer so I took a chance and motored back stopping and checking for higher than normal heat along the way. I made it back to the boat launch ramp with no problems. I pulled the impeller out as soon as I got home and sure enough it had lost a vane, but lucky it was in the cup and was easily recovered.

This is my only Kiekhaefer era outboard so I am not familiar with these pump impellers. Could you please tell me a correct part number for this impeller? I have not been able to come up with a part listing for this early of a serial number, the old impeller inside diameter mesured .456", and seemed to fit properly.

1963 kiekhaefer Mercury Merc 110 9.8 serial 1615044 .456" short shaft Cloud White

I googled 1963 9.8 Mercury impeller and it took me to an ebay link for an impeller that fits the same diameter shaft. Check it out.

Not sure but those things are pretty standard. Go to ********** and see if you find a picture of your motor or something close to it.
