I have a cracked impeller on my 1964 18 hp Elgin outboard. It takes a part number 901065-1 impeller which is no longer available. Are there any compatible impellers that I can use? Is there any company who can make a new one on a 3D computer?

The impeller is the sprokett looking piece in the photo.

I’m not familiar with that impeller, but you can contact the
person below. Some of the Scott made impellers have lots
of vanes like yours. Is your Elgin Scott made?

If you come up with some measurements, shaft size, thickness,
OD, you can compare with some charts available. Below are a couple
of charts.

Club member Brian Wilcox makes new impellers.
Call 810-794-7685 before 8 pm est please.
Or email Baron0418@att.net. please note the b must be a capital

Prepare to be boarded!

Thank you, I believe it is more the Westbend type. The list you sent may be useful in a pinch but I think I will inquire from Brian to see if he can make one that is more compatible. Ken.

I have Elgin Microfiche, from when Mercury bought out Force, which was Chrysler and West bend before that. I think their reasoning at making the microfiche was so they could get rid of all the dead stock they had. There are a few impellers still available. If you give me your model number, I can look it up.

Long live American manufacturing!

HI Bill, my model number is C571.596941 serial 596941.1057 the part number of the impeller is 901065-1. 4 other members cautioned using Sierra 18-8903 or Quicksilver 47-F436065-2 as they only have 5 splines and it might not have as much water pressure as a result. Do you have any experience using an impeller that fits but has less splines than the original? Any help would be appreciated.

It’s too early in the AM for me to access the microfiche….I’ll double check when I get home from work. But if you know that the 47-F number is right for your engine, that’s probably the one I will come up with. My feeling is that a six vane impeller in a sixties West bend product will be fine. A long time ago, I modified an 18 hp West Bend to use a 9.9/15 OMC impeller turning in what I think was an ’80s 4 hp OMC plastic/stainless pump housing. The impeller was half the size of the original; but I figured if it would cool a 15 OMC, it would cool the West bend. It cooled GREAT and the motor ran like a top. What a great, great motor that was. Why didn’t I keep it???

Yup, that’s the one my microfiche says, too. The 47-F901065-1 comes up on Mercury’s dealer website as NLA but doesn’t list any supercession. The 47-F436065-2 is the same one I use in my Force 15. It has six vanes. I have not had it on a boat yet but in the test tank the motor runs so COOL that it concerns me. I mean it’s not even luke warm. (No thermostat on this early one.) If it indeed fits in your pump housing, six vanes will be PLENTY to cool it.

Long live American manufacturing!
