Ok,I have a BB 502hp and I have not run a t-stat for the last 2 seasons. My temp guage never really moved,as I would suspect with no t-stat in the motor. Starting on July 4th,my temp now reads between 130 and 140 degrees. Now guy's, I know thats not too hot,but what I don't understand is without a stat why is my guage reading at all. In my mind that makes me think there is excessive heat,or water issue problem,and if I were running a stat I most likely would be running too hot............Any ideas

corroded connection???

?????????????????????

 

[OldMagicfloat]

Well it's a thought,but I would not think the guage would always start at 100 and end up at 130...Kinda shows me it is working ?????
But who knows,thats why I'm asking

Maybe your impeller is starting to fail and not moving as much water?

THe water finally warmed up enough in the lake. And you may need an impeller

Just a Thought

Check your impeller. I'm assuming that you winterize your engine with the newer non-toxic antifreeze, and some of those antifreezes have a tendency to wear out the impellers prematurely. Usually takes around 3 to 5 years before this shows up.

Might also check your water intake and hoses, plus the exhaust manifolds for any sort of blockage, if you haven't already.

Thank's for all the imput guys. But for the record,a new seawater pump was put on last October,and the manifolds are new.....But that doesn't mean something could not go wrong in that area.. Thank's guys

When you picked up that wood in the river some could have been sucked up. I lost an impeller to seaweed at Hammond a few years ago. When I backed flushed the system I got broken impeller blades and a clump of green seaweed. You could have an obstruction in the system somewhere that is not allowing the water to exit the boat properly.

how did you backflush it?

 

[Candyman]

I take the outlet hose off of the seawater pump and lay it in the bilge. Then I take the hose off of the thermostat housing that comes from the coolers. Put the garden hose into that hose and crank up the pressure. Most of the debris gets caught in the coolers. BN should check the thermostat check balls going to the exhaust. They could be corroded shut not allowing excess pressure to bleed off.

Let me know if you want to run down to Pastrick tomorrow night.

good idea,,, I wanted to flush mine anyway just for yucks and see what happens,,,, I know his balls are ok, we checked them ( man that didnt sound right !! ) we are going to put a thermostat in today .

You guys want to run out to the marina tonight to see what boats showed up for the run. I hope to leave Alsip about 7:30 Saturday morning. I have an empty boat if you want to run with me.

Hmmm,,, tonight sounds good, let me know when/where,,,, tomorrow,,, undecided,,,,, I'll let ya know later !!!

What is a good reason for not running a thermostat?

Why not run 180 degrees where your engine is fine, most efficient and produces the most HP?

.....and burns the condensation out of the oil !!!!!!!!!!
