I never seem to reach any higher than say 125 on raw water cooled PCM
What is your gauge reading? |

I'll bite. Not a bad photo this time.
Combine that with some oil talk, and photos and you'll get some action. |

Remove the t-stat housing, and we will better be able discuss condition, and that usually generates more heat.

Maybe you left out a gasket.

Or Blew One Either way, think it's time for you to inspect all the hoses. |

If you turn the raw water intake a few twists you will find it too hot to touch.

What does the thermo stat housing have to do with LOW temp reading?

Not sure, on any of the responses...
Do you think maybe the gauge is bad? Or wiring has gone funny? |

Because the Thermostat is inside the housing, if its stuck open, or failed open then you will never get the engine up to temp. If the engine is actually getting up to temperature, and the gauge is just reading wrong, then you may have a wiring issue between the gauge and the sender in the side of the block, or if the sender was removed, and put back in with some kind of teflon tape, or plumbers dope you may no longer have a good ground at the block, which will also make a gauge indicate low.

If it's only getting to 125 you may not have a T stat in there.
My comment was to run it Wide Open Throttle (aka WFO) for a while and see if that doesn't raise the temp. |

What does a shot of your t*ts, or some t*ts have to do with your boat temp? |

I think we all recognize the internationla symbol for a low temperature condition.

More likely, a few loose screws. |

Benj - loose screws? The wiring going to the gauge itself? I will check that....

No question someone needs to get up in that motorbox and do some probing

Loose screws and corroded connections mean higher resistance and a low gauge reading. Get the IR gun out and shoot the temp next to the sender. If it reads higher after you have cleaned up the wiring, open the T stat housing and check what's inside. |

I guess, after checking all the wiring and screws nuts, and all that!Plus cleaning contacts...
What am I looking for inside the housing? I know there is a thermo-stat.. But other than that,? |

I have the same issue, gauge reads barely over 100* with fifty degree water temps. Last year mine would get to around 125* with 70* water temps. This info is all from the gauge. I need to hit the t stat with a laser temp gun.

You need a starting point, and I'd say cracking the thermo cover to see if it's in there at all is a good place to start. A replacement thremostat should come with the gasket. |

You may need to look inside as well. It's a simple operation. |

Buffalo-- I had the impeller replaced , my brother claims to replace those every 2 seasons...So after that my readings on the temp gauge went way down?
I doubt it was because of that.. Now earlier in the season I was getting uo to say 125 to 135 maybe.. I will have it gone over, thermo housing and all that ,, ty again... |

The impeller is doing its job; thus the lower temps. The thermo regulates how much water goes through the engine or bypasses. It's a thermostat not unlike the one in your house.

Usually 2-3 bolts and a gasket.

Buffalo, my housing came off over the winter. T stat housing is clear. Over in another thread I was trying to find a t stat. Tested mine and all is good. So t stat and housing is non issue. |

Lin, Since you brother seems to be up with impellers and oil, why not have him do the maintenance? |
