Thank you, your suggestions tell me the test was not correct, so I will retest. Not the best to try and test with a warm Engine, in a boat that has been winterized and it gets into the freezing range at night, so will do the best I can. Engine is low HR and would start good, so problem is in the test. Next week temp is going up a bit so will try once more. The initial problem started after dummy me, overrevved the poor defenseless Engine, ( was testing props), to answer other question why not put it inside, no room, on the trailer 38ft. long. Thanks.
