Neptune and Posiden don't get involved in those. Buddha and all those other Eastern/Oriental guys died long before the first transmission cooler was invented, so they wouldn't have a clue what you are praying about.
Jesus and Muhammad also predated things like diesel engines so your prayers would fall on deaf or at least ignorant ears, there.
I don't think there is an Egyptian God of machinery, but I could be wrong on that, cause they had plenty of them.
The American Indians had their Spirits for all things, but somehow I missed the part where they had them for machines.
So who exactly do you pray to on mechanical issues, that would have a clue what you were praying about? lol

If your engine operated at around 180 degrees, as most do, then you were trying to cool your oil with water that hot. I can't see any benefit from that.
Perhaps you were running keel coolers up there, which is common, so your engine and heat exchanger cooling water was always fresh, as those are closed systems.
The engine operating temperature does not change because of the water temperature you are operating in, so it wouldn't matter if you ran your engine in Alaska or the Gulf of Aden. As a matter of fact, if you are operating a diesel in very cold water you have a limiter on your circulation water so you can limit water flow and not cool your engine too much.

Re: Why is nothing ever easy!!

One thing I have learned in 45 years of fixing things is that you can do it right or you can do it over, and over, and over. The easy cheap fix is rarely right unless you are planning to sell to a sucker the next day...... Just saying.

Re: Why is nothing ever easy!!

An auto trans dumps it's heat into the car rad. Realistic operating temp range for tranee oil thinks thats's ok. Heavy use like towing/trucking requires an auxiliary hx in series .Hot weather conditions may require an upgrade to a bigger radiator to accommodate changed conditions. How is that different from a properly scaled marine system where heat is dumped into an adequate supply of ocean water from 180 fresh water in the engine cooling system . In my installation the Hx's were mounted engine cooler on top over oil cooler, F water did a U turn at one end and returned to the front handy to engines water pump and expansion tank . S went to exhaust riser ( small T for the pisser)making the hosing easy.Worked for me ,not for all perhaps.

It can depend on where your are tapping into the system. You want to tap in on the outlet side of the freshwater cooling system before it gets reheated by the engine. You may find the temps a lot lower there than on the input side of the cooler however its best to check first. You really do not want the transmission so cold that the lube doesn't flow well either.

Usually engine temp is measured at the thermostat where the hot coolant flows out to the cooler and not where it returns to the engine. If coolant flows into the engines water jacket at 180 degrees F then it can be well over the boiling point by the time it exits the block.

I can pray to the God Elon Musk for he claims to perform modern miracles on a regular basis.

And he would NEVER lie or exaggerate.

Sander I respectfully disagree.

It's 3x longer than my optimistic estimate -- them multiply that time by 3x because I didn't allow for squeezing into a place upside down where no %$#@$%# human being could possibly fit !

Capta that's easy.

Sailors INSTINCTIVELY know the name of the god to call on when doing boat repairs.

Every sailor I've ever known at some point in a project screams out MOTHER F#CKER !!!!

And his assistant SON OF A B!TCH !!!!
