I have a Jabsco that has eaten another impeller after only 20 or so hrs of use. I fear it was an OLD impeller (it came in a bag of spares with the boat). I didn't see any cracks when bending the blades and I did lube it during install. Anyway.....I'm going to put in a Globe impeller (I've ran them in all of my other boats and been happy). My question is 8 or 10 blades on the impeller? Which will move more water at same RPMs. Naturally the 10 blade unit has a larger diameter body and shorter blades than the 6. I have looked for about an hour and typed in every combination of words I could think of to pull up this info. I can't find any information regarding blade count effect on impeller performance. Any of ya'll have 1st hand knowledge about this one?
I think all the spare impellers and belts I got with the boat are going to be relegated to emergency use only and I'll buy new for routine change outs.
