2003 19 bay stainless prop pitch

[sijake]

Posted this under 19 bay and did not get a reply, so trying here. This boat is standard, has 115 hp Yamaha. Somebody must have the same boat with a stainless prop that they are happy with. Would appreciate pitch so I can replace a well used aluminum one. Thanks in advance.

I Had A Rapture 17" Pitch Half Cup 3 Blade S.s. Prop For Primary And It Did A Great Job Of Pulling Kids On Tubes To Jumping Up On Plane

Thanks for the reply. That sounds like where I will start.

Another example of how the search tool on the home page would have helped for I know I posted these links before

Hard to beat that test data as a good starting point

Would the same go for a 115 OMC on a 190 Cool Bay?

No two boats are loaded the same, nor have engines that develop max torque in the exact same RPM range. It takes time to get one dial in for your needs and hull.

Here again, that is why I recommend using this prop http://propulse.jetshop.se/ so you can adjust the pitch settings to give you a good base line to use in a metal prop going forward (if needed) and then keep this one as a back up unit on the boat that will not rust and weighs next to nothing
