I am 47 and still try to rip it as much as I can. I have a 2008 Moomba Mobius LSV with 1100 lb sack on each side of the engine in the compartmens, 400 lb in the middle and 650 lb in the front if needed.
It has the standard prop that came with the boat when new. I'm not sure exactly the size. 4 blade.

I first off slalom several times until I'm burnt and then fill up one side for surfing for a few rounds.
I finish with a little wakeboarding with all sacks for maximum wake.

Main question is: Given the above, does the prop make a difference on the wake for surfing or wakeboarding?
Would an upgraded prop from the factory one help any? If so, which prop?

Thanks for any info.
