|I recently left my boat docked half a day during some choppy water. When we went to go out for the day i found that the gas breather vent on the side of the boat had been broken off from the boat hitting the dock. About 10 minutes on the water and the engine started cutting out and backfiring, then it wouldnt even start. Could water through the vent reach the tank and cause this problem? The boat is a 2000 Centurion 315hp Mercruiser Inboard.|
|Yes water can reach through the vent. it should be a cheap, quick solution. Merc sells fuel stabalizer for this very problem, a $4 bottle of it should do the trick. |
the symptoms also could indicate a vapor lock, which could happen with hot weather, less than full fuel and rough water. try the fuel stablizer first.
|How does it work? there might be a lot of water in there|
|If it has a carb you can unplug the supply line and drain the water out. There is a product called heet that will bond to the water. They have it at the autoparts store. I think the fuel stabilizer is more for when you store your boat to prevent varnishes from forming.|
|i recently got a bad tank of gas at my local station. ever since then my centurion runs sluggish when i have full tank of gas, after a couple of hours it does ok. anyone else having a similar problem? |
Replace your fuel filter and see if that fixes it. Worked for me.
