Either of the above will work well. They are both AC plugs. The R43TS is an automotive version with an extended tip. It will burn a little cleaner. Th MR43T is the stock marine plug.

They used to make a MR43TS that I ran but for some reason they stopped producing it, so I switched to the R43TS to keep the extended tip....no problems in the last 3 years..knock on wood
