From the cooler hose leads down again to oil cooler and exhaust manifold than lower still to fuel cooler. Hose from fuel cooler leads to front of engine and up to heat exchanger.
Hope for an easy one. I will pray for you. Jim |
Tech was supposed to go out today but the weather sucked so I'm still waiting and praying.

It's a bit(h but you should be able to replace every water hose on the motor with it in the boat..... The last 2 years I've worked with some buddies doing ALL our own work (rebuilt 7 engines last winter) I've learned it may take awhile, but you can get it done.

Fatdaddy:
Before you start replacing things, check the pressure relief valves on the water system. If you trace the small white and orange plastic lines down to the bottom of the motor you will end up at a brass valve assemblies(may be partially painted black by Merc). These are dump for winterization and pressure relief valves and we have seen them stick open and fill the bilge with the raw water from the pump very quickly and overheat the engine. Find these valves, start the engine quickly and see if they are dumping. Might be your problem. Hope this helps. Regards, Ray @ Raylar |
sounds like a main water line under the engine is off or as ray said the dump is stuck.
by thw way do you have sea strainers? |

fat daddy...
not trying to be a cynic here but , while all the advice above is all good and correct in all respects, im a little mystified why you feel people hundreds of miles ( or maybe even 1000's of miles ) away can possibly know more than you just getting down in there and actually using your own two eyeballs to see where the water is actually coming from. granted... it might not be easy or pleasant but, in the end, its whats going to have to happen anyway.... everything else is just postponing the inevitable and wasting time. |

The culprit, a torn hose, was fixed on Sat. a.m.. It ran perfectly again. Thanks to all, except one :D, who replied.
