I have a 2015 30HP four stroke outboard that I start it and let it warm up 3 min as required by the manual and then start up on throttle and about 3/4 to full throttle then horn goes off and then engine cuts back, continuous horn, turn key off then immediately restart and come up on throttle and it runs normal the rest of the day with numerous starts and stops while fishing. motor is pumping water fine and oil level is perfect, prop is good and tight and not a scratch on it. continuous horn according to the manual is one of three things 1=overtemp 2=overspeed 3=oil pressure. some days when I go out it doesn't do it at all but when it does it only does it on the first throttle up and then does not do it the rest of the day. any help would be greatly appreciated. boat is garage kept and used 3-4 times a week. thank you for your time
