I had swapped lower units as the gear case was shot as the boat would just sit there in forward gear and grinding occurred. After I swapped the lower units I took it on the lake and lost power like most of the power.
On another note I have an issue with a collapsing bulb due to a gas jockey forgetting my gas cap and having me to replace the gas unit assembly because mine was so old could not find the correct gas cap. And ever since I been dealing with a collapsing bulb. (Could this be a reason to the loss of power?)
Also the shaft with the teeth on the lower unit installed is smaller by very little (not sure if the lower units were compatible) but once I removed I installed and it seemed to fit very well.
