Night and Day Difference — No More Communication Issues

Rating: 5 out of 5 stars

I purchased the NK Controller with the upgraded HD Communication Cable Kit, and it has been a night-and-day difference. I was having communication and connection problems with my previous wiring, but since installing this upgraded setup, everything has been working great. The connection has been reliable, the controller performs exactly as it should, and I haven’t had any of the communication issues I was dealing with before. Very happy with the upgrade and would definitely recommend it.

Rating: 5 out of 5 stars

I ended up breaking my last one. It is nice that you can buy the parts to keep your setup going if one thing breaks without having to purchase the whole unit again. I didn’t have the HD last time. The bigger connections are nice. Thanks!

NK180 Pro Replacement Controller

Rating: 5 out of 5 stars

Talk about customer service. Filled out the form and without hesitation the warranty controller got approved and it was shipped in time for the next fishing trip the following week. Shipping usually takes awhile since I'm in Hawaii.

Bought a brand new...

Rating: 5 out of 5 stars

Bought a brand new nk 300 i had a small issue with the thcontrol.And cathey will not connect it properly that frustrated me greatly but, with the help of customer service at Newport vessell they helped me to resolve the issue very quickly by troubleshooting just a couple connections. Make sure that your connections at your throttle controller/motor are clean and tightened down properly.

Works great

Rating: 5 out of 5 stars

This is the perfect spare to have or if you have an old warn out controller! This is compatible with the NK180Pro along with the NK300! Quick tips: if you have issues with your controller, try to recalibrate! Head over to YouTube for the video. Also if you’re having more issues, plug directly into the motor bypasssing the communication cable! This will rule out a faulty cable

NK 180 Controller

Rating: 5 out of 5 stars

Wow, what a great company with an awesome product. I had purchased two NK180 Pro electric motors from Newport. The controller for one of them wasn't displaying my battery level properly. After explaining my issue to the service department and completing the proper warranty forms, I received a brand new controller in the mail. No haggling, no procrastination, no more questions or requirements, and FREE of any and all charges! They stand behind their products and what an absolute charm they have in the 180 Pro. Thank you Newport! RMc

I bought a NK300 in May of 2023 and didn’t take it out of the box until march of 2024 , when I did the motor controller handle was broken, I emailed Newport and they sent me a new controller when I explained to them what happened. No bullshit , “it’s been almost a year” ,”why are you doing this now “ they are 100% true to their product! I bought 3 of these motors and I love them! Great customer service!

Frequently Asked Questions

You know how they say there’s no such thing as a dumb question? Well, they were wrong, but here are some common not-so-dumb ones

I need a new controller. Will I need to purchase the controller and the upgrade kit?

No, this controller comes with the M12 connector preinstalled and the kit to upgrade the connector on your motor.

What motor(s) is this compatible with?

This upgraded controller is for the NK300 and the NK180PRO only. If you need a controller and cable set for the NK180, you will need to purchase the controller for the NK180 and the new M12 upgrade kit, if you need the communication cable.

What tools will I need to install this upgrade?

The only tool you will need is a heat gun or high-temp hair dryer to complete this install. We also suggest using gloves with heat protection during the process.

Is this upgrade kit required?

No, it is not required. However, this is the only replacement option now available, as we no longer offer the M8 connectors.
