Greetings all... As we inch closer to spring I've started shopping for some various items to enhance this coming boating season. One of the things I've been considering upgrading is the prop - from the standard white aluminum one to a stainless in the hopes of some marginal performance/thrust increase. Unfortunately I'm clueless.... I have searched & saw some comments regarding prop rattle, which I would certainly like to avoid. Can someone please educate me on the real life benefits & perhaps offer suggestions on which model I should consider? Thanks in advance!!
