Just got my new impeller kits (part no. 5001594)for my outboards (model E150TLCRD) and have a problem. The impellers are for use with the driveshafts with the section machined out (flat spot) for the key. My shafts are perfectly round without the flat part for the key (there is a key, but it fits in a slot cut into the shaft and then in a slot in the impeller bushing). Is there a different part number for the impellers, or are these suppose to work with both types? I know the impellers on sldie on in one direction, but I also don't want to burn up my engines.
