Author	Topic:   Yamaha Saltwater Series II vs Mercury Mirage Props
TransAm	posted 07-07-2008 09:43 PM ET (US)      I had a friend tell me that the Yamaha Saltwater Series II Props were very similar if not identical to the Mercury Mirage Plus props. I was wondering if there is any truth to this. I got to thinking that Yamaha came out with the Saltwater Series II prop design (from pervious Saltwater Series) about the same time Mercury went from Mirage to Mirage Plus design. I am thinking of purchasing a pair of Mirage Plus, but currently have a set of Saltwater Series II and wont bother if they are in fact identical, or virtually so. Also, if I were to adjust pitch on a prop, would it be better to adjust a 23 pitch DOWN to a 22, or adjust a 21 pitch UP to a 22.

I've had both propellers and a quick glance at both side by side will reveal to even the casual observer that there is absolutely no truth to it. By the way, the SWS II propellers are very good propellers and I think you would be wasting your money buying Mirage Plus propellers to replace them.

I believe Yamaha developed it as good imitation of the MIRAGE propellers. They are NOT identical. Both the Saltwater Series II and the MIRAGEplus is certainly worth trying on your boat. You'll never know how a propeller performs until you try it.

To my eye, it looks like a variation of the typical Yamaha cleaver shape, with the variation intended to provide more blade surface area by enlarging the diameter and changing increasing the blade surface at the outer half of the swept area (a little more soup spoon profiled versus teaspoon profiled).

"You can always have more pitch bent into an outboard prop, but you can't take pitch out without ruining it." Ref within this link's thread - http://www.thebassbarn.com/forum/showthread.php?t=145795
