Scott try a 3 blade prop and let us know how it goes...
may need to get a bigger ute mate!!
I tried a 3 blade on my 185cdi and liked it a lot. It was a Falcon 19.5 x 12 I highly modified. I broke it and haven't got around to doing it again, but I have 2 here ready to modify.
I have to remove a 3 blade for transport, so that's a problem.
Yes, a bigger ute would be good. Maybe a Silverado 2500 long bed
