Evinrude Intruder water impeller/pressure

Hey guys , I have a 1995 Evinrude Intruder E150GLEO. My first question is where is the linkage disconnect for being able to drop the lower unit to replace the water impeller? Second question is, what should the water pressure be at idle and at wot? Thanks in advance for any and all info, I appreciate it.

Click on the Johnrude tips link at the top of the board, 6-8 at idle anything over 18 at WOT.

I appreciate the link but my motor is a Intruder which is excluded in that "how to" section. It says the shift linkage is different. I appreciate all the help though. Thanks.
