Default Re: motor bad again. Help!

i had the motor built 2 times,
original motor and crank excreta.
so I kneed a water pressure not temp Gage, along with a oil temp Gage huh.
I did put my hand on the oil filter and I tell you it was probably over 180 mabey 240 or so 2 second touch hot.!!
what would cause high oil temp and hou do you keep low oil temp?

Bring Out Another Thousand .......again and again and again and again

Where should I go or should I get a new crate motor or should I get one from 1800runsnew.com?
I wish I didn't ever mess with it.

I was warned by serveral different engine builders that the runsnew motors were truck blocks and not Merc long blocks. Try perfprotech.com, they claim to be Merc long blocks. They are GenVI motors, so I think you will need some other parts.

Have a marine engine builder build a motor. Lots of automotive guys think they know how to build "any" motor but marine engines are different. Remember, when your running in a boat it's like driving up a steep hill all day long at 4800rpm or whatever you cruise at. It's a tough environment for an engine.

And no, you need a water pressure AND temp guage alone with an oil pressure and temp guage, when they read out of the norm shut the thing off and figure out what went wrong.
