New/Used boat to me and made mental note of gauge readings first few times out and
noted that the temperature gauge normally stayed at 150. The last couple times out
temp read 100 and that appears to be the starting point on the gauge, and it may of moved
5 degrees.This is an I/O. Does this sound normal? Thanks Larry

Sounds like a stuck open thermostat. It may just have a chunk of something
wedged in it.
