1989 Evinrude XP 150 warning horn - 01/18/16 08:40 PM
I recently bought a used boat powered by an Evinrude XP 150. First time out I babied it and ran it between 3500-4000 RPMs. No issues. Second time out I ran it around 4500-4800 RPM..the warning horn started beeping on and off in rapid succession. It is my understanding that is for low oil. I noticed the primer bulb was not getting super hard when primed. I also had asked the person I purchased from if he had replaced the fuel lines and bulb since we all love our ethanol gas....he hadn't. I went ahead and had the fuel lines and bulb replaced. New bulb is getting and staying hard. Compression also good for a 27 year old motor..all 6 within 4 pounds. Now let's forward to my third trip. Ran the engine at 3500-4000 on the first run...no horn. Decided to "test" it to see if the primer bulb and fuel line fixed the warning horn...proceeded to run it 5000-5200(5200 was WOT)....fine for a few minutes then the horn came on. Shut it down and proceeded to fish for a couple of hours. Then I took the last hour of my fishing day and tested the engine. I ran it at 3500-4000 for about 25 minutes straight without incident. Then I stepped it up to 4500-4800...after a few minutes the horn came on. I immediately took it down to idle speed...horn went off...stepped back up to 3500-4000 for a few minutes and no horn...stepped it up to 4800 and horn came back...back to idle..ok...back up to 3500-4000 for the rest of the day and no issues.
Any input is appreciated.
