Author Topic:   re-prop 17' outrage

I have a '99 outrage 17' with a '98 115hp Johnson oceanrunner ficht ram. The boat currently has a 15-1/5 x 15 omc alum. prop. I have talked to my friend Sal (known on this board) and he suggests that 13.75 x 17 ss may be more suited for this boat. The boat reaches 5500 rpm and speed is about 32-34 knots, this is in the ocean in North Cal. Average water conditions are around 4-6' at 10-12 secs. I'm not sure if water conditions info is relevant to prop sizing. My goal is to be on plane sooner at lower rpm if possible. I stay on plane at about 3200-3400 rpm now and that is too fast at times in our ocean conditions where I spend 98% of the time.
Thanks

I have a 96 Outrage II 17 with an Opti 135. With the right prop and your engine height set right, it can make all the difference. With the original setup (alum prop and engine all the way down), the boat was unuseable when SF Bay got sloppy. Now I can keep the bow down at a lower RPM (25-2800) and get a smoother drier ride. Go with Sal's recommendations. He's the expert here.

I don't know anyone turning a 15" or greater diameter wheel with an OMC V4. I use a 15.25" x 15" Yamaha Saltwater Series wheel on my V6 Yamaha 150 HPDI.

I think that the Bombardier Viper in a 13-7/8" x 17" would be the right stainless prop for you.

What differences can I expect between a 3 and a 4 blade prop in my conditions? My motor is set on the first set of holes, how should I determine which set it would be best?
Thanks for all the info!
