How to Choose RC Boat Parts for Pools and Lakes
Start with a ready-to-run speedboat, then match spare propellers, batteries, and seals to that hull. Self-righting hulls flip back upright after a capsize, and 2.4GHz remotes reach up to 292 feet. Propellers run from 32 mm to 80 mm, with bores from 2 mm to 4.76 mm. Check diameter, pitch, rotation, and bore before you order any prop.

Which speedboat fits a beginner?
The self-righting hull flips itself back upright in seconds after a capsize, so a beginner spends time driving instead of wading out for a rescue.
Two speed modes let a beginner start slow and move up to full speed when ready, with a 2.4GHz remote.
The remote reaches up to 292 feet, and the LED lights switch off to save power on daytime runs.
The clear-hull boat runs over 100 minutes on a 3.7V 1800mAh battery, with 10 LED lights showing through the hull.
How do you match a propeller to a boat?
Check four numbers before you order: diameter, pitch, rotation direction, and bore size.
The CNC 3-blade prop measures 40 mm across with a P1.6 pitch, a 4.76 mm bore, and right hand rotation.
The 36 mm pair holds one clockwise and one counterclockwise prop for twin setups, with a 1.4 pitch and a 4 mm shaft fit.
The 32 mm 3-pack is counterclockwise only with a 3.18 mm bore, and the 80 mm 10-pack press fits 2 mm motor shafts.
What does the ESC program card change?
The card sets running mode, motor direction, low voltage cutoff, punch, and timing with buttons instead of throttle stick beeps.
Two LED displays show the item number and the value, so each setting is visible as you change it.
Low voltage cutoff runs from 2.6V to 3.4V, punch has 5 levels, and timing runs 0 to 26.25 degrees in 8 steps.
Which battery and plug fit?
The 2-pack holds 7.4V 600mAh Li-ion batteries with a black SM-2P discharge plug and a white 3-pin charge plug.
Two adapter cables convert SM-2P to male mini Tamiya plugs for boats that use the mini Tamiya style plug.
The listing names H100, H102, H106, H108, and H120 boats, and warns that some newer versions use a different plug.
How do you keep water out of the hull?
One rubber bellow slides over each pushrod exit, sealing the hole while the rudder and throttle linkages move freely.
Each bellow is 37 mm long with 5 mm and 1.4 mm end diameters, and cracked or stiff boots should be replaced.
The motorcycle-style boat adds EVA sealing strips and waterproof covers, and the clear-hull boat seals the battery compartment.
What did we check on the bench?
We checked each listing states its size, fit, and plug or bore figures.
We matched every price here to the live store price on November 12, 2026.
We counted 3 images on each speedboat listing, 4 on the CNC prop listing, and 3 on the ESC card listing.

How do you set up a first run?
- Charge the battery fully and check the plug matches the boat before you leave home.
- Check the propeller is tight and turns the right way for the hull.
- Close the hatch and check the seals sit flat with no gaps.
- Power on with the boat out of the water and check the rudder moves both ways.
- Start in slow mode, stay within sight, and bring the boat back at the first low battery warning.

Frequently asked questions
What happens when the boat capsizes?
The self-righting hull flips itself back upright in seconds. The clear-hull boat rights itself automatically with its anti-tip design and low center of gravity.
How do I know if a propeller turns the right way?
Check the rotation in the listing: right hand turns clockwise viewed from behind the boat. The 36 mm pair includes one clockwise and one counterclockwise prop.
Will the 7.4V battery fit my boat?
It fits boats that use the black SM-2P 2-pin plug, including the H100, H102, H106, H108, and H120 boats named in the listing. Check your plug first, since some newer versions differ.
Why use a program card instead of stick beeps?
The card shows each setting on two LED displays as you change it. Timing, punch, low voltage cutoff, and running mode all set with buttons.
