Hi, I'm new to the forum. Any help would be greatly appreciated. I have a mariner 115hp outboard. I am not sure of the year, but the boat is an 85 model and from the looks of the motor it is probably the same year. I can't read the serial number otherwise I'd tell it to you. Anyway, I just bought the boat last month and have had it on the water twice. Each time it will run nicely wide open for about 2 minutes then all of a sudden it will lose power and die. Then i wind up struggling to crank it again (it will if i squeexe the bulb several times) and going idle speed back to the launch to get it out of the water. I filled it up with gas before i took it out the first time. it probably had 1/4 tank in it then, and i have no clue if there was water in the gas. After i got it back home, I changed the spark plugs and replace the fuel filter. Then took it back out again, and it did the same thing. I was able to keep it going if i kept choking it, but it would eventually lose power and die anyway. it acts like it was running out of gas. I don't know if this has anything to do with it, but it has an autoblend oil tank on it that mixes the gas and oil for you. I don't know anything about how those work, but it has two leads on it that were both connected to the same terminal on my battery, so if it is battery operated then it wasn't working at all, but if it works off the engine drawing the fuel through then maybe it was. But I think that is probably my problem, that the mixture wa way way too lean. I am thinking of mixing the gas and oil myself and bypassing the autoblend. You think that would solve my problem of power loss and engine dying? Any help and advice would be greatly appreciated. Thanks,
