My Yamaha has 1200 hrs and runs great but lately my fuel consumption went from a average of 3.23 KMPG to 2.76. I do a lot of trolling at 2000-2100rpm.
1st I did a compression check and it's 112,111,111. 100 hr hours ago it was 115,115,115. Could this cause a higher fuel burn?
2nd I thought maybe the thermostat had a problem and it was running cool. I checked the thermostat housing and head while on the hose and it was 100 degrees. The sat is 122 degrees. Should it run warmer at idle on the muff? I'm in he middle of changing it and hope it runs warmer and more efficient.
What do you guys think?
