Re: reinstlation of mercury lower unit
it shud b pretty straight forward. if the impeller and everything is already installed, all u have to do is bolt the unit back up to the rest of the engine. get sum help and let one person hold the lower unit while the other directs the drive shaft, water tube and shift rod into their proper places. if the drive shaft gives you n e trouble going in, jus turn the flywheel a bit so that the splines match up on the shaft. one other thing...its a good idea to make sure both the throttle or shifter on a tiller model and the lower unit are both in neutral.
