leak in transom plate

[sabastianunf]

When I trim my lower unit up i see a leak. If i am in the boat looking past the motor to the trasom plate the leak is at the bottom right. does any one know what could be causing this?

Re: leak in transom plate

If it only leaks when the drive is trimmed up my first guess would be the drive shaft bellows. When the drive is down the bellows is compressed and probably not leaking but when raised the bellows is stretched and any holes or tears would be open. This is not good as it can sink your boat plus the water in the bellows will destroy your gimbal bearing and u-joints.
