I have the same engine with the side draft and a dash warning light will come on at 225.
I have hit 225 a couple times but it's always 110+ towing. I'm not racing anybody, I just slow it down and drop a gear.
I'm running one of these from my trailer to the motorhome for solar.
Its has to twist to disconnect and I like it better than the ones mentioned above.
