Hi Jeff,
You didn't provide a lot of information, but a few possibilities are a problem with a temperature sensor (motor too hot or a sensor that thinks it is too hot) or excessive voltage drop at high currents. Excessive voltage drop can be due to a loose connection or a bad battery. I would check all the electrical connections and then have the batteries tested. Good luck.

Subject: Re: [Electric Boats] Electrical issue
Hi new to the board. I have a 20 foot pontoon boat with ray electric motor. All electrical wires have been replaced within 2 years. When I throttle from slow to fast power cuts out completely. Reverse or forward. Has anyone had this problem? I can go slow but once I increase to a certain speed engine cuts out.

Hi All
Thanks for the feedback.
Here is a bit more info hope this helps
I would be looking to get about 2 hours from battery as mostly I am sailing,
the battery's must recharge as I sail
I obviously need a generator to recharge when not sailing or no wind
And for domestic power
The alternative is buying both a Diesel engine and a generator
Why would a commercial outfit be different , we live on Desi 24/7
I don't believe weight will be an issue as Desi weighs 30 tonnes and at the moment we carry 1000 ltrs in two tanks one of which I would convert to battery space
