Hello All, I have a 1988 90 hp Yamaha. The power trim unit is working but I have the normal corrosion on the motor which I have on order to replace. I have also seen some very small amount of fluid leaking.Can anyone tell me is there a rebuilding unit for this power trim? If not can anyone make some recommendations? Is this job within the capabilities of a average handy person. The motor replacement does not area to be all that difficult but I don't want to get in over my head with the rest of the unit. I would like to give it a try because the it seems the Yamaha units are much more expensive compared to the other manufactures.Thanks in advance for your reply....
