I'm putting my first water pump kit in my 1990 Johnson 150 & I can't get the shift rod loose to drop the lower unit. I finally got the bolt out & the shift rod seems stuck?? The bolt I removed was on the linkage cross shaft & went into what appears to be a pinch clamp. It was a major butt-pain to access & required a long 7/16 wrench & a lot of patience to remove... Could i have removed the wrong bolt or is the shift rod just stuck?
