I've got a 2002 200-hp 4-stroke. I took it to a local Yamaha service center to get it serviced. I received a call from them telling me that they couldn't get the lower unit off to replace the water pump. They had tried everything, even using a torch. I brought it back to see what I can do with it. I was able to loosen the back side of the unit(where the zinc sits) but I'm having problems getting the front side loosened. I don't see any linkages that may interfer with the unit coming off. The service center told me it's corrosion that's holding it together, which I don't believe cause I don't see any salt build-up inside. I've tried the screwdriver technique but that's causing more damage to the casting. Might there be a linkage that I'm not seeing or an easier way to take the unit apart? <br />If anyone has any new ideas, please let me know.
