I am trying to install a water pressure gauge on a 2005 Yamaha F115. I previously had it installed on a 1996 Yamaha C115. I am not sure where the water pressure sensor is screwed in on this newer engine. I suspect the bolt
just under the poppet valve housing ( now called PCV valve - pressure control valve) on the exhaust cover. I included a picture of where I believe the sensor is to be located. Can any knowledgeable person chime in here and let me know if I am right and if not where it should be installed. Thanks in advance.

out of memory all I can tell you is to consult the marine rigging guide.
any yamaha dealer will have a copy of it and it will give you a chance to pick up a new sealing washer anyway.
