I have an 07 3.0 with 113 hrs on it and now the season is winding down I wanted to address some minor things that I noticed of the summer.
We bought it brand new in 08, its moored and used mostly in a brackish river.
Issue 1
Trim sender has an erratic gauge. I took the starboard sensor apart and cleaned it with all parts are good and clean. I tested the rotor with a MM and get continuity across it on the very top and bottom of one side. The gauge now will show down with the out-drive fully down and fully up in any other position and will jiggle around when the drive is moving.
I see the rotor is available from Merc. does that sound like it will fix my problem?
Issue 2
This summer it seemed to me that it ran a little hotter then it has in the past. At speed over 15 mph it would be around the 185 mark but at idle/headway it would drop to the 175. My IR thermometer shows the motor in the 170 range.
On the hose it stays at the 175 and in the past I swear it would be just above the 150 mark. I took the T. Stat out and ran it on the hose with it out. Full water pressure gauge would not raise above 100 with the hose at 1/4 open it stay at the 160 mark.
I tested the t-stat on stove (its the original factory 160) it would start to open at 176, fully open by 180 and be closed again at 160. I ran this test 3 times with the same results.
The impeller was changed 2 years ago only because its was 8 years old and I probably should.
The elbow is original and I have taken it off to inspect its condition yet.
Every spring the water pump on the block seems to get stuck to the case and tap with a rubber mallet fees it and away we go.
