Mercury Fury Prop on 08 Puma / 250 Pro XS

OT I use a hydraulic jack plate and can makeem turn whatever I want. RPMs dont mean much to me as long as its over 5700 rpm and less than 6K. Then based on top end speed I can tell whether or not its a good prop or one that needs some work. But to answer your question specifically, the 28 Trophy turns about 5800 – 5850 and the Tempest and Fury turn a little over 5900 – 5950.

I plan on running one in the next few weeks or so on my FTD. Thanks for the heads up, good info. Judd Lasiter

The reason I asked is that I used to have two props that ran my boat exactly the same speed, but one was at 6000, the other was at 5400. The 5400 was not so good a prop in the summer as it caused the motor to drop off the front end of the horsepower curve and was pretty sluggish, while the 6000 rpm prop (all done in the winter) would spin fast enough in the summer to be useful.. If the RPMs he pulled were all pretty close, then the Fury looks like an interesting thru-hub for those that like to run thru-hubs. BTW for interest, I currently have two choppers I like. One is a 26″ re-pitched to 27 with the blades thinned down just a bit and the chord reduced as well (blades are not quite as wide). This prop grips like a tractor at any speed and once on plane, speed is pretty proportional to RPM. I have another chopper, the “small-eared” variety made for the smaller motors, which has a smaller diameter, with a 28″ pitch. It is way touchy to engine height and load. Examples: big blade chopper runs 76mph consistently, with one or two on board, around 6K rpm. small blade chopper runs 83 mph consistently, with just me on board. With two it will barely break 65 without adjusting the engine height down a bit. More noticably is that at 5K rpm it will run 50 or so, but another 1K rpm takes it well past 80. Thats why I was asking, trying to determine how well the new Fury bites or holds the water at speed, in turns, etc. I know several that might like to give that a try. Also a 27″ might be interesting as well, or even a 28″ for those that have made a few “improvements” to their motor so that the gearcase ratio is not tall enough to prevent over-revs… I will say that the Merc guys know their props, perhaps excepting the older laser props that were a bit plain vanilla… BTW, as far as engine height goes, all my props have a single sweet spot. yes, I can raise the jack plate, increase the revs, and also increase the slip. So the RPM value I was looking for above was “max RPM at the max speed engine height”. Normally going too high will drop speed even as it ramps up RPM… And that RPM number is not very useful. But the one from optimal speed is, because that is most likely optimal slip with respect to engine horsepower band.Last edited by oldtimer57 on June 3rd, 2008, 5:10 pm, edited 1 time in total.2008 Pantera Classic2014 Mercury Pro XS 200

I wasnt able to open it up due to boat traffic but it is a good prop. Holeshot was very similar to the 26 Trophy but putting on the trailer was the typical 3 blade put it in the bed of the truck if you wish . Midrange might be slightly better, not much though. As soon as I get an opportunity to run it WOT I will post more of an opinion. I had it up to almost 70 and handling was good. Judd Lasiter
