" Hello...I have a couple of questions on installing a new water pump repair kit on my 90hp Johnson. I picked up a book from the library and even though it's very informative it doesn't answer everything. I have a 1987 or 1988 V90. One question I have is about removing the gearcase. It says to remove the trim tab screw which I have. Then it says to remove the countersunk 5/8 in screw between the trim tab cavity and gearcase housing using a narrow wall socket, and it shows a picture. The problem is in the picture it shows only one screw (bolt) and there are actually 2 and nothing is said about the second screw. Then it goes on to say remove the screw from inside the trim tab cavity (if used) with a 1/2 in. socket and extension and it shows a picture of that also. I guess my question is do I remove both the screws that are located just ahead of the trim tab or do I remove just one and if so which one? My next question is what is the reason for removing the shift rod retaining clip, is it so the shift rod will come off with the gear case? I'm sure I'll have more questions as I get further into this project but that's all for now. Thanks Bob "
