Ditto I have been using a Gen 4 Sevcon without a Heat Sink for two years and overheating is not a problem. It will depend on the rating of your Sevcon, but heat dissipation will be improved if your mount it to aluminum plate with a large surface area. Forced air over the heat sink is also another option.

Ryan, I did not use a heat sink and haven't had any problems with it getting warm. FWIW, I have a 37 ft sailboat with the same 10kW Thunderstruck kit I think I saw that you are using. I typically run the motor around 30 to 60 amps, and have taken it up to 125 amps or above for 10 minutes or so without ever having an overheating problem with either the motor or the controller.DarinOn Sun, Jul 12, 2020 at 10:09 PM Ryan Sweet <ryan@ryansweet.org> wrote:How have you folks mounted the sevcon controller? With the heat sinks on there doesn't seem to be a natural way to mount it. Do you put it on rods? Or mount it with the heat sinks up against a panel?
Pictures anyone?
Thanks!
