New glass fiber reinforced composite material propeller, updated pitch, camber, and thickness for high thrust application. Better performance with new propeller and minimizes efficiency lost through cavitation.

Adjustable motor shaft to fit almost all small to medium size watercraft. Keep the propeller deep enough in the water to maximize power efficiency, and still have a long enough motor shaft to operate.

Quickly released taper-lock transom mount, effortless one-hand operation. Adjustable points to switch the motor from running position, shallow water position, and tilt-up position. Industry top quality to build and resists flexing, warping, corrosion, and UV damage.

Seamax trolling motors come with updated technology and over the industrial standards to build. The ultimate goal of this new version is to greatly improve motor performance, extend the product lifetime, and increase your boating experience.

To decide which model to take. If you use it as your main motor, you may want the 35” shaft model. If you will mount the motor on the front of your boat, or you will put it beside your main motor on the transom, you may want the 40” shaft model. It is best to keep the prop top tip under the water line 4-6” to maximize its efficiency. And make sure your boat can have a 24V battery group (12Vx2) before you can purchase the 24V 3HP model. Since the battery is heavy, make sure you can handle the batteries before making the decision. Or we suggest the new lithium battery as your best option.  

It is not a must to have an external circuit breaker since it is just one more protection from outside the motor. One of the biggest differences compared with traditional DC motors, Seamax PowerMax has had the electrical circuit protection built-in already. So, your motor is always get protected from seaweed damage.

Great selection Seamax high thrust models. Excellent performance for lake or offshore use. Powerful and lightweight motor with Smooth and powerful operation; Easy to push an inflatable boat or aluminum boat fast and get closer to the fish. Built-in sacrificial anode for better corrosion protection. Transom clamps locking feature to keep your motor always safe.The Brushless AC motor is controller by its built-in PCB that is microcomputer-based. It can real-time monitor the condition once power is connected. The motor will give a beeping sound warning if a mistake is detected or the battery is low. For example, when the prop getting stuck by seaweed, the motor can be shut off automatically and with a beeping sound warning. That is much better than a traditional DC motor with an external circuit breaker connected.12V brushless electric motor can provide 65 pounds (2HP equivalent) thrust output. Fully adjustable 35" powder coated marine grade aluminum shaft. Work great with different watercraft. Built-in sacrificial anode. Good for saltwater and freshwater use.

New patented step-less speed controller for smooth forward / backward speeds operation. with real-time battery voltage indicator can show the battery condition when boating. Aluminum telescopic tiller handle with wide-angle adjustment. Anti-theft quick released taper-lock transom mount with effortless multi-angles adjustment.Telescopic handle with wide adjustable tilting angles. An ergonomic extendable telescopic handle puts control at your fingertips. Solid aluminum and steel lower unit with powder coating finish. Suggest running with a marine deep cycle battery. 5ft Power code should be the right size for a battery box in many different boats Our motors are durable and high performance and come with 2 Years limited warranty coverage within USA & Canada.

Choose a Circuit Breaker - Our 2HP/3HP motors are designed to draw 50A/40A during their full-speed driving in the water. but the motor could draw more power if working at harder water conditions. If you want to select a circuit breaker for more protection and as your main power switch, it should be at least existing 15% of max Amp capacity. Also, depending on the quality of the circuit breaker, the breaker's performance will drop during its lifetime. So, you may want to pick a breaker at 25% over the max. We suggest a Min 65A circuit breaker for the 2HP and Min 50A for the 3HP model if you need one. Since the AC motor has electric Power Control Board (PCB) built-in, in most cases, the motor could cut off the power by itself if a problem detected. 

High-Frequency Q&A -The most problem is with the Battery when your motor not working. If your motor stops in the middle of the water with a beep sound warning. The first thing to check is the battery level indicator light. Your battery voltage is low if Red light only or even no light to display. The PCB of the motor will cut off the power when the battery voltage is out of working range.  After the power cut off, the battery won’t be drawn by high output, so its voltage will be recovered by itself. The motor can run again but it won’t last long, maybe the last couple of 10 seconds only. This problem may happen when using any kind of battery. You may just use your battery for another device, or your battery may be only a few months old. I saw a lot of those cases since you won’t be able to see the battery condition from your eyes. So below battery section is very important to know.

Notice for Motor User Modification – We can understand many customers may want to use our electric motor for Kayak fishing. And our best suitable motor is the 2HP 35” shaft version. Since our PowerMax is the brushless AC motor technology with digital speed control. It is easy to make mistakes during the modification. For example putting the 12V power or LED to the digital controller cable will cause the PCV dead. Also, our standard warranty policy is not covered any motor modification. We want provide this note for your guideline before purchase this motor.

The motor head’s internal wire is PVC-coated copper wire, except for the power cord, the controller wire is very basic. we suggest you can take photos and ID the cables before you cut the original wire. Don’t connect the cable in the wrong. Do the power cord at the latest step could be safer. Also, you can test-run the motor in every step to make sure. A wrong cable connection may damage the AC motor’s PCB (Power Controller Board) inside the underwater unit and make it hard to fix. We suggest the speed controller extension cable could use the bigger gauge wire for better signal transit reasons. Wire connector should use waterproof heat shrink crimp. Many of the original internal components have a waterproof seal, but the top LED display has not. Keeping the motor shaft covered from rain will be needed, even it has already had a cap seal inside the shaft. Always think about the rain & water issue to ensure your electronic components are all safe. Once your modification started, the motor’s regular warranty is ended, but we will give support and parts when needed. (electrical wire and waterproof connector can be purchased from a local electronic store or eBay & Amazon)

First of all, please make sure you can have base electronic knowledge before starting. You should test the motor and make sure everything is normal since we won’t accept a claim after your modification started or even you placing back the unit. It is great if you can learn the motor’s assembly drawing (Accessories Sales Figure) on our website since we also selling motor parts.  Seamax can have the parts available for most repairs. But we may not be able to provide full instructions for troubleshooting if it is a modified unit.

Record your self-instruction is very important, that includes taking photos of your every step, placing the parts in the right spot (keep no missing) during the work, and writing a note or drawing to help yourself if necessary. Also remember, disconnect the 12V power during your process. And double-check twice before you want to connect the power for a test run.

We strongly recommend keeping the handle (Part# 24001459) with the speed controller (Part# 24001268) together during your work. DO NOT take it apart before your 1st test runs successfully.  Please know the motor need to detect a Neutral Position before passing its self-test when 12V power connected. Reassemble those 2 components may be easy to make mistakes and cause Neutral position failure. And such a motor may keep beep sound warning no matter how you turn the handle.

Since the motor’s PCB installed in the underwater unit, please make sure the motor shaft top is fully sealed before water testing. You may want to use marine grade silicone to reinforce the original water seal. Please know the water leaking into the lower unit during the shaft will cause the motor dead. Also, you get to make sure NOT putting 12V power to any of the signal cables or controller cables. So your detail photo or mark down are both important for your success. 

Battery Charger & Maintenance - Fully charge the battery does not mean the battery capacity is good. It will depend on the condition of the battery. To select a good battery and maintain the battery in good condition, you may need to follow the instructions below.  1) Purchase the right marine deep cycle battery or a new Lithium battery. Check the battery voltage with a voltage meter when making the purchase. 2) The AGM deep cycle battery will be a good option for the price and lifetime. A better battery should be always heavier if the same type. 3) Please find a local professional battery store to purchase your battery. Best not to purchase your battery from an Auto shop. Do not use the starter battery as your trolling motor battery. 3) Always fully charge the battery before storage or after your boating trip. An overdrawn battery kept for 30 days may cause serious internal damage and affect its lifetime. Many battery damages could not be able to recover. 4). You may want to use a good battery charger for your battery. We suggest using the NOCO genius charger with maintaining feature. It could help your battery to restore performance by following their instruction.

AC Motor High Frequency Resonance -Our AC electric motor may give a small noise sound like vibration when at a certain RPM or speed, you may think about the motor with a bad ball-bearing issue. Actually, this status is from the AC motor high frequency resonance. When you have a chance to turn the prop by hand, you can feel it almost getting stuck and big difference comparing with traditional DC motor.

AC trolling motor is a brand new design, but limited to up-to-date technology, such a High Frequency Resonance is normal. Also, every units could be variable or none. Your motor's Resonance point is also different when testing in the air or running in the water. This is not a warranty issue. Otherwise, if this is the problem from ball-bearing, a faster speed could be worse.

User should bypass your motor's Resonance Speed when running the motor, so either run your motor a little bit slower or faster when Resonance Point hit. Otherwise, if you keep running the motor at the resonance speed for long time, its small vibration may finally damage the ball-bearing and bring water damage.

Our suggestion is to find out your motor Frequency Resonance RPM point. Don’t let your motor stay at that RPM. Also, test the motor in the air should not exist 1 minute of time and follow the same rule.
