You can run it sittng on the trailer BUT you need to have a water (garden ) hose putting water in the cooling system while it is running . I have the same boat , on the left side , cooling hose runs by the alternator , I remove the hose clamp at the medal filter ( ? ) turn the hose up and put the water hose down into the system . You need to run the engine until it reaches normal running temp .
