Is there a difference in design/application between the mercury vengeance (13 1/8 X 16) and the michigan wheel rapture (13 1/4 X 15/17)(i know the pitch is different).<br />I have a 2005 merc 115 4/s on a BW 190 Nantucket. I single hand fish most of the time. At WOT it hits the over/rev cutout @6200rpm. I would like to go to a larger pitch. I have a merc vengeance prop 13.37 X 14 installed now.It is the standard prop supplied with this motor.<br /><br />Thanks for your help<br /><br />Steve
<br /><br />They don't come with props. It's still a bit of hit and miss. I don't know how much throttle you'd have left once it overrevs. If it overrevs at 3/4 throttle, you'd want to change a few pitch inches. If it's close-but-no-cigar, maybe only an inch or two. But consider your load. When you go out empty, you need a different prop than when you motor back with a good haul of fish in full livewells. But who'd want to swap props all the time? Gonna have to settle for one or the other. You need to prop for the load, and manage the throttle when you're light. When you're light, less than full throttle IS an option.
