Re: WOT RPM's and cruising RPM's
I finally raised my engine as per the great advice received here. I raised it two holes though (instead of one hole at a time) because most everybody thought the overall adjustment I needed required two holes. I did encounter some ventilation when cornering, but this was strong cornering and not standard steering I typically expect to make. I realize one hole down will help that and will keep that in mind.<br /><br />The goal was adjust the engine height before making a final decision on the prop. I was unable to make a good top end run because I dented the factory aluminum prop while on the water and before the water was calm enough to do a WOT run. So now I want to buy a SS prop but haven't confirmed whether the current 14x23 or a 14x21 gives better peformance. The RPM/MPH figures I quoted earlier should still be the same except for incremental gains I hoped to have achieved through my engine adjustment.<br /><br />I realize I need to "lock in" the right prop size before ordering a SS one. I want SS because I fish a tidal river with lots of stuff and I wan tthe extra confidence of the stronger prop. But now I need to replace the aluminum one but still feel I need to confirm the right prop. What should I do? Also, a buddy says a 14x23 prop is "too much prop" and will spin out when my boat gets loaded down. He says I should get like a 13x21 to rpevent it. I said getting your RPM's right at WOT is what drives prop selection. Should I consider a smaller prop??!?<br /><br />Thanks!
