Newby, but here goes.
Original engine ran at approx. 145 degF on dashboard temp gauge.
2006- New short block installed due to major issues.
Temp now ran at about 100 degF on the temp gauge, and the water coming out of the drive was about that temp. Engine prone to stalling when placed in reverse at the dock...of course only at the dock. Mechanic who did work was "OK" with 100 degF...
Skip forward to 2007- Started engine for first time on muffs. Ran fine...I think...
-dash gauge showed about 100 degF.
-water exiting the drive (port side) was stone cold and good flow...basically the same as what I was putting in the muffs.
-water exiting the drive (starboard) was getting quite warm and lesser flow than port side. I commandeered a wall thermometer in a vain attempt to check the temp. (125 degF before I shut down the engine)
- I have a Seloc Manual (yes, I know I will be chastised).
-Following the cooling system flows, it appears that both hot and cold water could be ejected through the drive. Remember, I only ran for 5 minutes before I shut down.
-Questions:
1) Mercruiser Owner's Manual quotes 143 degF for the correct thermostat. Where is that signal coming from?There appears to be two sensors on the thermostat body, located 180 deg apart, and each looking like they are below the thermostat element.
2) Is it normal to have different temp water coming out the drive?
3) Should I install a new t-stat, or am I just being anal?
PS: I am intending to have the t-stat pulled by the mech who did the short block job...something doesn't seem right.
Thanks for the forthcoming advice. This boat has got to get some run time this year...more time in shop than in water the last two years. That's why I'm on I-boats...need to learn to fix some things myself, or else hang a 4- Sale sign!
