i took a fuel sample and found water in the fuel. it has twin out boards the starboard motor was running fine. some i over looked fuel as a possible cause. but when i took the fuel samples the port motor showed much more water in the fuel than the starboard motor. so this may explain the star motor running better. i have already order the carb rebuild kits so i think i will rebuild the carbs on both motors and drain, clean, and refill the fuel tank with new fuel. thanks for your help, Can I ask you more questions if this does not resolve my problem? And also I have heard of people disabling the vro pump and mixing the gas and oil? Is this a good idea? If not how often should the vro pumps be replaced? And how do you know when they are failing?
