Plumbing??

[4trax]

So how would I plumb this in the right way? (Sorry it's so dark try brightening your screen up) Or do I just leave it?

Switch the hoses. You want the line from the pump to "T" to the bottom of the risers and into the water pump ports and then the exit side from the thermostat to the outlet on the risers which would be the top.

????????????????????? :confused:

So water would come in from lake to the bottom of exhaust and then it comes out exhaust to to the block where water pump would normally be and cools the block or warms it and then it goes out T-stat housing to top of exhaust to exit out of boat correct?

What is the purpose of having it this way? Is there something that this guy is trying to cover up as far as engine runs to hot if it done different then this or maybe exhaust gaskets leak water? I just want it to be hooked up the way it suppose to be. It runs REALLY cool in summer time like 100' or 120' the only time I've ever seen it like 150-160 is after I shut it off for 15-20 min then go to start and it starts like it's hot. I've heard that runnin to cool makes engines not last as long.

jets put out way more water then you will ever need. You only want 15 psi max.
The reason to go to the lower manafold 1st is twofold.
1 to preheat the water going in the block to help stop thermal shock
2 to help cool the exhasut.

I have no gauges on this. It just comes in from the lake and goes directly into motor out to bottom of exhaust and back to lake.

no valve? You really should put one on, or you could spend the coin and get a bypass kit. You really don't need a guage since you can use your temp as a guild.

Fill me in what are you talking about?

Correct.

Your pump should have a controll valve at the inlet to the hull for the cooling water.
Your pump is capable of putting out far more pressure than any gaskets in your engine's cooling system were ever designed to tollerate, and they will blow, just depends which one. Intakes are most comon, head gaskets happen too, neither is good.
Restrict the intake flow and do not restrict the outlet flow and there is no need for a t-stat setup IMO. Engine temp will be dictated by flow volume and will vary about 30 to 40 degrees, highest at idle, lowest at full power.
Some folks run a thermostat setup tho and that is fine, just a far more complicated setup, my jury is still out on if it is really definitively BETTER or not. I have had zero trouble without one for 27 years now.

So I have to constantly be adjusting this ball valve once I get it in so I run the correct temp. What about all the pressure how do I regulate this? I run this boat all summer like this and now I'm finding out that it's all wrong boy am I lucky I guess?

no once you get it set you can leave it alone, or you can buy a bipass kit for about $100 so that it dumbs extra water out the back. Peronally I don't see a need for a bipass kit.

So just get one of these http://www.rexmar.com/images/page169.jpg
And hook it up and once I get where I want to operate for temp. just leave it there? Do I set it to where I'm idling along about 1200rpms and 160 temp and temp will fall as I get on it or should run warmer then 160? My question is at what rpms is normal for what temp. If that makes any sense?????
