Hello guys. I am a new on the forum. Prop advice needed.

I have a 2004 SD187ob deck boat with Yamaha F150 txrc. I run an aluminum 13.75x19 prop around 5500 rpm at WOT. I found good deal on used yamaha reliance 14.25x18 SS prop. 
Is this good prop for my boat?
Thanks for your time!

    While you're waiting for other members that have a similar boat to respond, you might want to play with the Yamaha Prop Selector on their website.  It will give you a decent education on props for your boat/engine combo.

    I have a 2014 Hurricane 188 Sport with a Mercruiser I/OB 4.3 liter. I was running off-brand props, and went back to a Mercury Brand prop. The performance improved quite a bit as Mercury stated their aluminum alloys were stiffer than the off-brands, and out-performed them.
    Long story short make sure you use a name brand prop- You'll feel the difference
