Tohatsu M18E2 18hp 2stroke
This is a follow on from my last post. I thought i had a carb mixture issue as engine was running poor last week. I set the carbs and had it running nice for well over half an hour in a bucket of water.
Took the boat to the harbour today and started it up. Being that it was sitting much deeper in the water it idled a bit lower, but didn’t stall. I trawled around the harbour for about ten minutes and all steamed fine.
Once I took it out the harbour I got the boat onto the plane for about 2 or 3 minutes and it started to bog down again, so slowly headed back to the harbour where it eventually died. When trying to restart the engine I could barely keep it idling, every time i started it, it would run for about 10 seconds tops, splutter and backfire before cutting out again.
The tank has fresh fuel bought today. I measured the 2 stroke oil in a measuring jug to be as precise as possible. The fuel lines and prime bulb is new. Compression is fine.
What would you recommend I look into next?
I’ll check all the Earth wires tomorrow and see what condition the fuel pump diaphragms in.
Luckily my little auxiliary 4hp has run flawlessly for years, but hate the feeling of being on the water when things start playing up.
