Just purchased a new 4 stroke nissan, 6 horse, first time in the water it was hard to start and just as hard to keep running. Also alot of vibration. Motor worked well in the tank at the dealer and was kept on a stand for a month in my garage before going in the water. Before I take it back to the dealer any idea's on what it might be, spark plug foul etc. Sure would like to find a fix rather than getting it out of the water for a 30 mile drive.Many Thanks
