Hello All. Datenight our North Pacific 39 has been sold and we await the delivery of our next Datenight a North Pacific 45 in late November.
Diane, the High Commander, decreed we will not be without a boat this summer. Enter Cheap Date a 1976 Trojan 28 Sedan Bridge.
It fits our need perfectly and runs well except for the exceptions. The port engine runs hot and seems to use coolant. I can find no leaks and an inspection of the raw water side of the heat exchanger shows no antifreeze. Running the engine with the coolant cap off shows no bubbles eliminating (I hope) a bad head gasket.
Port engine sends coolant to the hot level of the overflow tank but does not suck it back when the motor cools. Yesterday I changed the cap to a different one that came with the boat. No coolant left in the on engine tank, overflow full. I did notice that the cap on the overflow was loose. Must have forgot to tighten it.
Today I will drain the overflow, make sure the cap is tight and buy a new "radiator" cap. My next thought is the thermostat. The coolant tank on engine is square with two bolts sticking out of the top. Everything I see on line is round for the 318. Can't find a thermostat housing anywhere and suspect it may be under the tank.
The photos I took with my phone won't transfer to my laptop so I will try to post them later.
This would not be a big deal if we were home but we are five days into a two week cruise. I have been in contact with my mechanic but have not found the solution yet. I am hoping the TF brain trust can come to the rescue.
Thanks,
Rob
