Daryn posted on my behalf while I was setting up my login. It is an '04 Xstar with the 350hp MCX motor. I am located in Dallas, TX and the boat has the factory prop today.
Kyle,
I would check out the Acme 1285 or the OJ 470. You will get a lot better hole shot from either while loaded down. Your top end will decrease but the low end performance will be worth it.
Thanks,
Spence
