Replacing impeller on newer style Merc raw water pump

[boatrboy]

Question on the impeller install. Would a hose clamp at the midpoint work to compress the vanes to get it started. Then remove the clamp and twist it the rest of the way in? Your tool is more elegant but hose clamps would be more available.

I have used zip ties in the past also. My worry has always been are the zip ties or hose clamps sharp enough to put tears in the vanes? Probably not but I decided to eliminate that thought completely.
