Hello All,
I have had my 2003 Triumph 170CC with factory Yamaha 70hp 2 stroke for about 5 months now and I have had an intermittent warning buzzer at random times. So backstory:
I can run it all day with no issues, and 5 minutes into the next day it could go off. It mostly goes off when I'm at low speeds coming off plane (sounds like a poppet valve) but once has happened at plane and the governor kicked in. Typically I'll turn it off and let it sit, sometimes for as little as 1-2 minutes and start it back up with no issues and run the rest of the day, sometimes it just wont go away for a while. At first I thought it was the overheat alarm, so i started out by replacing the whole water pump kit, thermostat, poppet valve, flushed the engine with on-off etc. with no avail. I can touch my hand to each cylinder when the alarm is going off, although I bought an infrared thermometer that will be here tomorrow so I can verify without a doubt.
That being said, it still doesn't explain how it will be fine all day and give me problems right away the very next day. Then last week I went to start the boat but when I turned-key nothing even remotely attempted to fire/turn over, so after 5-6 tries it finally kicks over with no problems at all. As soon as I get up on plane (-1min later) the alarm goes off and governor kicks in. Could this be electrical? Would the ignition or throttle not getting 12V cause the buzzer to sound? This has been very hard to troubleshoot since nothing in particular will make the alarm go off, it just happens randomly.
Other info:
- I always make sure I have proper oil levels and it does burn oil
- Since I use it a good amount I have been using non-marine grade gas on the notion that I have friends who do the same without any problems
Any help would be greatly appreciated!
Thanks in advance
