I have been having an issue with running hot
not to overheating but near the redline on a possibly inacurate really cheap guage
the heat issue was after long (45 minute plus) idle zone jogs and shorter (10-15 minute)
3000+ rpm runs.
also after the long idles the engine would bog if power was applied and sometimes long crank times for restarts
I installed a new Teleflex guage and sender yesterday and decided since I had never changed the stat
maybe I would for good measure and when I took the housing cover off ....there was no stat and looked like
there hadn't been one for a long time
the PO had changed the engine shortly before I purchased the boat and I wonder if he left it out due to the heat of breaking in a new engine.
anyway...would it be possible that my installing the correct 143* stat could cure my problems ???
guess I will find out next week but looking for some reassurance that it won't make things worse.
ran it on the muffs for about 40 minutes yesterday and it never exceded 140* on the new guage.
any input :huh:
