Prop for Outrage 18, Honda BF150

It performs reasonably well with the current prop, which appears to be a generic aluminum - turns right up to the 6K redline. I don't have a speed measurement, but it's starting to chine walk at WOT so I'm guessing high 40s. However, it just feels to me that the prop isn't gripping very well - seems to ventilate a bit on initial accelleration, and in some turns. So I'm advising her to get a decent SS prop, but I need some help on size. The existing prop looks like a generic black aluminum, and it's in decent shape. I didn't see any markings on it anywhere, and it doesn't seem to have much cup. From using a prop calculator, with RPM = 6K, gear ratio 2.14:1, a guess at 8% slip, and a guess at 47 MPH, I come up with 19-pitch. Can anyone confirm this from a similar boat / motor? If it's a 19, I'm thinking to go to a 17-pitch in a Stiletto Advantage II, but with the motor's wide range of allowable WOT RPM, might consider going with the 19-pitch and bringing the WOT RPM down a bit. Again, if someone has specific experience with this combination of boat and motor I'd appreciate hearing about it. I also forgot to check where the motor is mounted so advice on that would also be appreciated. Thanks! Tim

A few salmon trips now but no WOT as the seas have not been accomodating. So far I had a 19 pitch on with resluts of low RPM's. I went to a 17 pitch and now get in the 5750 to 6000 range. Please remember I have not been able to fully run it up because of the seas (fully trimmed in motor) but so far it looks like a 19 pitch is too much. I will be looking for a SST prop and not sure myslef how much of an effect I should expect to see going form an aluminum prop to a good SST.

You tell us you have an aluminum prop an I think we can stop right there; that propeller is not good enough. salmonboy -- We are discussing an Outrage 18 with a Honda BF150. You have a Mercury 150. Those two motors have different RPM ranges, and different gear ratios so it *might* be they need different propellers. Let's explore the possibilities for your boat in a new thread you start while we continue to discuss Tim's boat here. I have some solid advice for you I will share in your new thread.

Member Personal Page Posts: 1072 Comments: 2 Joined: 09/07/08	Thanks Tom - mail sent! I also checked her mounting height - it's slammed all the way down now, so I think we'll try coming up two holes with the new prop. Tim
