Caroute S300 36V motor with sleeve, retrofit this Duffy 18'

This Duffy 18' electric boat, took out the original inboard electric motor, and added a Caroute S300 36V motor.
The rudder shaft postion drilled out the hole bigger. Then a new fiberglass sleeve shaft was epoxied into the the rudder shaft holder. After, the fiberglass sleeve was sealed with fiberglass which's about three coats.The S300 36V motor was installed through this fiberglass sleeve, and connected with steering arm inside boat.

The boat reached 8 mph. 2KW motor runs really strong.
There is no gearbox, no belt, no noise inside boat any more. The motor compartment area also converted into a cooler/storage area.
All the components are rewired and all the connectors are placed inside a plastic box to protect them from the moisture.
The S300 wires' connecting is also simple, it's easier to rewire than to trace the old wiring.

 

Good for you.
I know the motor noise you speak of, I drove a duffy, commercially.
They are expensive to run as the parts are proprietary ( costly ).

What part of the states is CN?
( You do realize this is on the world wide web? )

 

Edit: After I posted I realized this thread was started by Caroute and not the owner of the Duffy.

I will leave my comment and suggestion as general guidance for anyone interested in the the longevity of operating an electric motor below water since corrosion and water ingress are two of the biggest issues with the technology:



While the motor is new, I would highly recommend adding a barrier coat to the motor housing which like most trolling/electric outboard motors is highly prone to corrosion, especially if used in salt water.

If the housing starts to corrode and the finish lifts, you can experience water ingress as the water gets past the seals.

You can vigilantly wash the motor down after each use if it is being trailered and day launched, but if the boat is to remain in the water, definitely consider adding barrier coat, and be sure to touch up any finish damage that might occur with use.

 

Thanks for your information.
This Duffy was retrofitted in Calfonia.

 

Thanks for your sugguestion.You are right.
Motor washing is necessary when out of water. For personal using, the sealer need to change in 3 years. For good wash and treatment, longest can be last 5 years. For commercial using, the sealing need to change each 1000 hours running.
For slat water, actually these aluminium motor use a lot for sailboat. And there is also stainless motor for choice with better performance in high corrosion.
For this kinds of trolling/electric outboard motor, most water ingress issues are caused by underwater hitting. Normal slaty water conditon for small boat is fine with the aluminium motor before you maintain the motor. For high salty or corrosion water conditon, it's better to consider other choice.

 

And whatever came of your old thread?

Yeah, it's a long time ago.
