Hoping someone can help with what appears to be a flooding problem on my 15HP Mariner 2 stroke. It is a 2003 model.
Whenever I start the engine, even from cold, it is best to disconnect the fuel line straight after pumping the fuel bulb; otherwise it will not start as it appears to flood. Once running cleanly, fuel pipe re-connected and all is good.
The first problem occurred last week after running for about five minutes, as I slowed down to about ¼ throttle, the engine appeared to flood and stop running. I had arrived at my destination, and did not think much more about it. After about 15 minutes, the engine re-started, however it did appear to be flooded, and only started when I removed the fuel line and spent 3 – 4 minutes pulling the starter cord. Once started, fuel line re-connected, no problem.
No more problems that day.
Several days later, it started as normal when cold (fuel line off until running cleanly), we then covered 2 or 3 miles at varying throttle openings. When running back to the Marina at ¾ throttle and nicely on the plane, the engine lost power and stopped. My first thought was that the engine had seized, although there were no signs, sounds or smells of overheating. My immediate concern was to get the oars out and row back into the shelter of the Marina, as a strong off shore wind could have taken us away from land.
I left it, convinced that it was b______d, and only after about an hour, decided to try and start it. Usual cold start procedure, fuel pipe off, and it started with a lot of smoke, cleared and then ran perfectly, with no signs or sounds of problem. Fuel pipe re-connected, ran fine.
Any suggestions gratefully accepted.
Many thanks
