I recently installed a new multi function yamaha guage in my boat. the temp guage flashes constantly.
i have checked the dip switches on the back and set them accordingling as per a previous response to another post.

Re: yamaha multifunction temp guage issue

thats not a model number
the ox66 225 was made from 1997 to at least 05 in a VX,S,SX and an L version.
need a model number to identify which trim sender you have.
if you have a 3 wire then set the switchs to 0ff,off,off.
sometimes you have to flip them on then back off.
is this a new from a dealer tach or a new to you tach?
if the switch settings are correct unplug the gray wire at the 4 pin trim harness connector under the hood and see if it still flashes.

Re: yamaha multifunction temp guage issue

the guage is brand new from the dealer. one other problem i did mention is that the trim guage also does not work.

Change the dip switch postions to Off, Off, Off. No change.
The model # is SX225TX?
Have not had time to research the trip problem yet.

Re: yamaha multifunction temp guage issue

We did find out that the trim sender switch is bad. Would that affect the temp guage?
