Yamaha T8 electric tilt failure
It goes down but not up. It seems like a clutch problem as the
electric motor runs fine. Has any one torn into one or had theirs repaired? |

Last time when my 115hp Mercury outboard has the similar problem, I tracked the problem to the failure of one of the electric module (called "servor" spelling???). I believe it is like a relay. One for tilting the outboard up, another one for tilting the outboard down. I identified the failed module by swapping those two modules, and found that the problem went with the module. Replacing the failed one with a new one fixed the problem. You probably need a Maintenance and Repair Manual to locate the modules because the owner manual does not likely mention anything about this. YMMV Jay Chan |

YMMV Jay Chan jay, you could be right. I'm not sure aboutt he Yamahas but some power trim units don't have a bi-directional motor, so the pump doesn't turn backwards for lift. This is controleld by a solonoid operating a valve in the hydrolic pump itself to switch directions of the flow through the pump. If the motor seems to "free-spin" while trying to lift the engine, I would say that it could be the pump not reversing the flow. But then again. have you checked the fluid level in the oil reservoir? If it's low, that could also be your problem. Or at least a contributing factor. |

OK, well that would mean, the motor is reversible, so either a relay or probably the switch |
