    1988 Mariner 50hp 2-stroke 3 cylinder motor dies randomly, but starts back up after a few attempts

    It didn’t seem collapsed but I can double check. The tank has a new top on it and was vented. Also have a new fuel line so I wouldn’t think it would be tank or line.

    1988 Mariner 50hp 2-stroke 3 cylinder motor dies randomly, but starts back up after a few attempts

    My 1988 Mariner 50hp 2-stroke 3 cylinder motor dies randomly. It starts up good cold. I drive it around for a bit hour-ish and then it will bog down and die. It sounds like something is clogged when it bogs down. If I give it a little gas, the rpms increase but it sounds muffled. It will start...

    1988 Mariner 50hp 2-stroke - Issues after carburetor rebuild

    Thanks jimmbo. I will be testing the compression and spark this weekend (time permitting). The gas leak is no longer happening when using the primer bulb (was happening before I rebuilt the carbs). Now the gas leak only happens upon shutting down the motor. I assume this could be a loose/bad...

    1988 Mariner 50hp 2-stroke - Issues after carburetor rebuild

    I recently acquired a 16' boat with a 1988 Mariner 50hp 2-stroke 3 cylinder motor. It was working for a while, but running rough. It would often shut down when idle or near-idle, but still was usable. In order to do a quick clean, I got some seafoam and created a mixture of gas, oil and...
