The Flo-Torq SSR utilizes Mercury’s proven Soft-Shift Rubber technology in a quiet hub kit that provides an NVH upgrade for Flo-Torq II hub applications where the maximum reduction of noise, vibration, and harshness is desired. [links]

Mercury transforms aluminum and stainless steel into the highest-quality, best-performing, most-durable marine propellers in the world. Also the best-selling, no surprise. Our experience, expertise, and proprietary technologies – Flo Torq®, Mercalloy®, X7® alloy, and PVS® (Performance Vent System) – give you a true competitive advantage. For best overall boat performance, there's no substitute for a Mercury Propeller. [links]

We couldn't find an aluminum alloy good enough for our propellers. So we invented one: Mercalloy Aluminum. So unique it’s patented, Mercalloy makes for higher-strength castings. Which allows for thinner blades that create less drag. Result? Optimal performance, optimal durability, better boating.

Mercury's Flo-Torq propeller hub might just be the most important part you never see. Not only does it flex during shift changes, reducing noise and vibration. If your prop hits an underwater object, it sacrifices itself to save your lower unit. Just pop in a new hub and you're back on the water, no service call needed. The Flo-Torq hub also makes Mercury propellers compatible with most engines on the market while also providing unmatched corrosion protection.

Each year, hundreds of boaters spend countless thousands of dollars on machine-shop equipment and bolt-on gadgets in their quest to increase outboard horsepower. Yet the easiest and least expensive way to improve performance is to change propellers. Regardless of your rig's size, horsepower or application, the right prop can make the difference, whether you seek increased speed, better handling or more power.

King of the high-speed tests was the Tempest, although it proved to be less than stellar in the timed 0-20-mph and 0-30-mph acceleration runs. In our fixed-speed tests, which measure rpm and overall efficiency, it was the clear winner. Second across the top-speed finish line was the Trophy, but it only finished in the middle of the fleet for acceleration and efficiency. [links]

For strength and durability, nothing touches stainless steel. Stainless-steel props can have thinner blades than aluminum props because they're here

Performance Issue I would like to correct: I want to purchase a Mercury Stainless Steel 3 or 4 blade prop with close to the same WOT and MPH (or better) as the Black Max mentioned below that came stock with my new boat. Both Stainless props tested took longer to get out of the hole and acceleration and speed diminished as well.
I like how the Black Max performs- I just want the same performance in stainless.
Please note the stock Black Max runs over the recommended WOT.

You did not say what type of battery you have so I will assume that this is a lead/acid Marine starting battery and not a Marine deep cycle. more

1. Make sure the battery cells are full by adding distilled water as necessary.
2. Place the battery on a good charger for 24 hours.
3. Remove the charger and immediately take a voltage reading. You should have 13.3-13.5 volts.
4. Let the battery sit for 12 hours and take a voltage reading. You should have 12.6 volts. If the battery is below 12.6 V replace the battery. If the battery is above 12.6 put a 12v light bulb on it for a load and test again. It should settle out. If not, replace the battery. [links]
