I got my bad news when I was doing the test run before I went back in the water. The new sending unit I had was bad
After figuring out that was the problem (no continuity on a meter)
I decided I was going for a boat ride. I will put the new one in on the lift.
I also punted on the oil pressure. I did find the oil circulation diagram and the port I see will work but there is no street ell that will work so I am making one. I also found out that the LED driver leads from the ECU for oil and temp alert are not present in the controller cable going to the console.
I am not even 100% sure there is a wire for them in the ECU cable, in spite of them citing the wire colors. I thought that would be a great addition for a buck or so.
