Hey GT. Where is the best place to run a in line water pressure gauge? What kind and where can I find the said gauge. Does any one make a water pressure gauge or do you just run a fuel pressure gauge.

Sorry for the thread jack


                                                                                        Thanks Jimmy.

Nice!  Thank you.   Oh and where should I mount it. Rite before the inlet to the motor or exit??

Yeah... post em' up!  I would run one of those but it's the same price, well a little cheaper, as the relief valve kit.  I may run one in the future but don't see the need now. 
I would think, after the pump and before the motor is where to mount the gauge.   that way you could monitor what's going in. 

WRONG!

Marine head gaskets are not just for salt use....Marine engines do not have the advantage of the anti corrosion protection of anti freeze. Thus making the electrolytic effects of brackish waters left in an engine most detrimental to the survival of the sealing surfaces...

I use brass freeze plugs and marine head gaskets in all boat engines. Cheap insurance IMHO...

A trait that marine gaskets also have is dielectric bonding of the sealing surfaces, this is like a good primer on bare metal on a paint job, it keeps the free iron from being exposed to the gaskets metal, which is how they function to begin with.

This has been a major debate among the boating community for decades, it is my opinion that the only time "standard" gaskets should be used is when the engine is not expected to be together for more than 6 months (read; full race deal)...

Sorry for the harsh intro, I feel strongly about this because I have taken apart literally dozens of engines that could not be salvaged because of the amount of corrosion in the sealing surfaces of the heads and block...

While I admire your strong opinion I must say I don't fully agree.  I pulled apart a  460 jet after 6 years of use with the felpro gaskets and they were absolutly fine.   Fresh water use in a clean lake.  So yes use the marine gaskets if you want.   But I sure wouldn't worry myself to death about it if I didn't is all I'm saying.
I'd be taking a hard look at that deck job and make darn sure it's square.   Did you chase the threads before you
put your heads on???  I think there is more happening here than water pressure.
