Replacing the PROPELLER on my Surface Drive Mud Motor (Backwater Performance Systems)

Backwater Performance Systems - Big Blade 12x10 Hex shaft 2-blade prop
Long overdue replacement prop installation for our mud boat, and test run. This prop made a HUGE difference in performance over our old worn-out prop. Highly recommend so far. Time will tell how durable it is.

Self locking nut, the more times you take them off it will wear out the locking feature, its always good to replace when the resistance of the nut starts lessoning. Kinda sounds like you may be having a bearing go out on the drive shaft. With a two blade prop balance is critical as it creates a lot of vibration thru the whole motor. Thats why its not a great idea the grind them down unless you balance them after, would be interesting to see the old prop on with it running at rpm;s, if the skeg looks blurry its shows the blade is out of balance

Whats the purpose of applying the marine grease?

[@daveriggs2033]

It’s self locking and use the uni wrench correctly

Did you gain any speed with the new prop?

[@tkflifeoutdoors7454]

Never clocked it for actual mph top speed. But the holeshot was significantly better. Faster on plane time. I could definitely feel the difference. And the motor runs so much better with the new prop. Our old prop was just so worn down from the sandy bottoms and oyster reefs we are in most of the time.

@@tkflifeoutdoors7454 okay so you’re liking it? I’m looking to buy the same prop

[@tkflifeoutdoors7454]

For sure

[@Lightsoutpredatorremoval]

Just got mine. Same prop same motor but the props look slightly different on the side that mounts to the shaft. Did yours also look slightly different?

[@tkflifeoutdoors7454]

Honestly don't remember. Did the swap almost a year ago.
