"I'm in the boat repair business and pride myself with the ability to set a boat up correctly. However, there comes a point where the boat needs more help to perform correctly than just the boat being set up and dialed in. Generally the only way to get that little extra edge is to have your propeller modified.
After re powering my Champion 203 with a Mercury 225 Pro XS, it was still not performing exactly as it should. I tried eight or ten different props and finally found which factory prop ran the best overall.
I then sent the prop to Steve at Steve's Custom Props. He immediately found that the one blade was 1/4 of a pitch off from the Factory! He then customized the prop and put his magic touch to it. All I can say is WOW. I got four to five more miles per hour, the hole shot is the best it has EVER been, and the midrange turning and handling is completely different! The boat had good bow lift before, but now it is incredible!
Having used many different Prop Shops over the years. There was one thing that made Steve's work stand apart. Most customers probably would not even notice this, but when the prop came back, it was polished and didn't have any grinding marks or other blemishes that many of the other shops don't take the time to correct. That impressed me as much as the performance difference!
If you want one of the best in the business to repair your prop, add more cup, or completely customize your prop, Steve is the guy to call!
North Texas Fiberglass
I just wanted to thank you for your help getting my new prop 'dialed
in' ! I finally got the boat out after our last conversation and my
zx200 got up to 68.5mph with a full tank and 15mph winds chopping up
the lake. A low tank and slight ripples and I'll be screaming!
Frequently Asked Questions
At Steve’s Custom Props balance and blueprinting is offered on most bass boat propellers, including our new et cut choppers.
A balanced and blueprinted prop offers better hole shots and a reduction in vibrations, as well as increased fuel economy and enhanced top end performance. Most new propellers manufactured today are not close enough in pitch tolerances, nor are they perfectly balanced and polished.
At Steve’s Custom Props your prop is placed on a pitch block and all blades are made to fit exactly in pitch and rake, then they are checked for accuracy on the pitch gauges. Then the propeller is perfectly balanced, and the leading edges thinned slightly for increased performance.
Then the propeller is finished in a very high polished finish.

1.) Level the boat. Place a level under the pad of the boat. Adjust the trailer jack up or down till boat is level
2.) Level the motor. Place the level on the cavitation's plate, and trim the engine down till it's level
3.) Measure from the ground to the pad, Write the measurement down
4.) Measure from the ground to the center of prop shaft, Write it down.
5.) Deduct the two measurements. You want the prop shaft 3 1/2" below the pad of the boat.
6.) Adjust the jack plate up or down, paying close attention the water pressure and max. engine rpms.
7.) On lighter hulls with low water pickups, running at a neutral trim angle is best. To find the neutral trim angle, simple turn the ignition key on when you have set the engine at level. The needle will be pointing to a neutral position. If needed mark the trim gauge for future reference.

train. Its job
is to take the

of a motor.
The power curve is the RPM range where the motor is developing its maximum horsepower and efficiently. If the motor revs beyond this point, it is over revving, and if the motor is not able to reach this point it is loaded down, which could have damaging effects in the internal components of the engine, as well as allow the engine to use fuel excessively. Either way, this causes poor performance and unnecessary wear and strain of the drive train.
Propeller pitch is speed, however there are also several other factors which allow a boat to perform to it's potential. Such as, pitch progression, rake, and cupping. Also the gear ratio of the lower unit is also extremely important to a boats potential for speed.
the hub is
Composite hubs are field replaceable. Just knock out the old sleeve and put in a new one. No technical skills or tools are needed.
Composite hubs allow you to limp home after impact and your drive train has a much better chance of survival without any internal damage.
Composite hubs are engineered to withstand high temperatures and will not degrade when exposed to high exhaust temperatures, this is a common problem with rubber hubs on high horsepower engines.
Composite hub propellers are extremely versatile. Replacements are made for all engine types. By simply replacing the thrust washer and driver adapter, you can install the same propeller on virtually any engine.
Rubber hub propellers are limited to one specific application. Replacements for rubber hubs are much more expensive than the composite hub systems and must be installed by a professional.
We carry a full line of replacement hub components.
design have a
lot to do with
how a boat
pad shape and
have a lot to
do with how
fast a boat
The more V a pad has, the faster it usually is because there is less boat in the water and thus less surface friction. With that in mind, it's also easier for the torque of the prop to roll the boat off the dead center of the pad and start the chine walking process.
We often hear the term, "Drive the Boat" with regard to chine walking without much explanation as to what that is.
This is not gospel, but it's what I think of when I hear the term "Drive the Boat". There is a balance between motor height with the jackplate, trim of the motor, and how the driver handles the steering wheel. Steering to me is one of the big tricks. You will start to learn your boat and its setup and as you learn you will know when the boat is about to start chine walking. As you see in the diagram, the rotation of the prop pulls the boat to the right, the key with steering is to counter the rotation with small steering wheel twitches to the left before the chine walking starts. All of these things together are kind of like riding a wheelie on a bike.

Just a note to say thanks for the prop work on my tempest plus. I finally have the boat I thought I bought.(TR21) I got it to the lake today for a test run. I never knew what people were talking about when they said they had chine walk on a triton. Believe me I do now. I took your advise and raised the prop shaft to 2-1/2" and went from 65mph to 74mph top speed. It might even have gone faster if I stayed on the throttle longer but I can see I need to relearn to drive my boat. The hole shot is also waaaay better than before you did the work. I have already recommended you to about everyone I know that owns a boat.
Thanks again for the great work,
Pitch changes and or progression changes are made to obtain exact top end rpm’s per application.
Rake angles can also be changed to obtain higher bow lift.
Leading edges can be modified for better hole shots.
Blade sharpening can also be done to help with an increase in rpms and higher top end mph.
All blades are matched exactly in pitch, progression, and rake angles.
All blades are highly polished after they are balanced to perfection.
Exhaust ports can be expanded or welded to obtain the correct amount of exhaust ventilation per application.
