1994 Force 90hp OB. Took it out once. Checked gear lube. Yellow and Milky. Changed lube and drain/fill plug gaskets.Took out again. Same lube condition. Pulled prop and retainer ring. Outer rear seal looks ok. Do not have puller to remove bearing spool.---Removed lower unit.Alot of water came out of front two mounting bolts. Upper seal and spline seal look fine. Only water visible is at the base of water pump housing and all over where the lower shift rod goes into the gear case.----- My theory is that since the water pump housing and the shift rod share the gear case cover as a base, the water intrusion must be occuring across that area. I am picking up a complete seal kit and impellar and replacing everything. My question is: Have I approached this correctly???? Thank you in advance for your input.
