Hi guys
Trying this forum as my engine isn't very common in Denmark.
It's a Tohatsu tldi 2001 50 hp. Last year is was running great with no problems. Then this spring when I tried to start it up after the winter it wouldn't start. After a while I found out that I had quite a lot of water in the fuel tank and now also in the engine. I drained the engine completely including the air rail which was unmounted. Afterwards I installed an extra fuel filter with water separator to avoid the same problem in the future. After this repair it ran again but sometimes suffered from high revs when idling. I have expected this to be some smaller air bubbles left in the fuel system.
Additionally the boat was fitted with 2 new batteries and a separator in between. Batteries are these (sorry it's in Danish...): http://www.bauhaus.dk/bil-og-bad/bade-badtilbehor/tilbehor/marinebatteri-dual-12-volt-80-amp.html
Then last week I took the boat out for the first ride this summer. Then when running at full throttle all 3 lights suddently started blinking, I got the warning sound and the engine went idling. I switched it of and started it again. The light went out but when the engine reached approx. 2400 rpm the alarm signal sounded again but without the lights flashing. I went back and took the boat up.
I then read some posts about the problem. I charged both batteries, purchased new spark plugs and went back on the sea again today. The problem went back running on the intended battery setup. Then tried running on both batteries in parallel. Same problem. Then I changed the spark plugs but again without any luck. Then tried to pump the ball during sailing but the problem comes back. It's possible to pump it hard.
I noticed that there is fuel in both the new external fuel filter and the internal under the hood when the problem occurs. I assume that they will run dry if the engine is suffering from insufficient fuel? The engine is charging with 13,88 volts at approx 4000 rpm.
So guys. What to do? Is the engine storing any error codes which could lead me to the problem? Could the problem be related to the water issue I had in the spring?
Right now I don't know where to look for the solution. The dealer is of course a possibility but I will start helping myself before going there
