07 21V cooling line up?

[wyatthawkins]

So I got my new motor and trans and v drive mounted in my boat.. How does the cooling lines flow in a 07 21V?

I'll check mine out this evening. Maybe I can snap some pics if I can get some lighting in it as well.

I can explain it more if you have a specific question. One of the things you can't see are that the manifolds each have a hose at the rear of the motor, that just ties in together much like the ends of a water hose.

[Plum Nauti]

From the hull inlet, it goes from one side of the v-drive then out the other to go to the sea water pump on the crank. That is the bottom hose. The top then curls up and goes into that distribution block topside.

[wyatthawkins]

So inlet to v drive to pump. Is there a trans cooler? My motor hoses are all there and plumbed but not the inlet or trans or v drive cooling lines. I was told I need a transmission cooler.

I am thinking the trans cooler is the metal tube inline on the top hose from the raw water pump at the crank.

The big metal cylinder here in this hose. I had something like this on my I/O, but it was power steering fluid in it. I'm thinking this must be what you are referring to.

Yes that is the tranny cooler.....two hoses from the tranny connect to it, if there is a dripless shaft seal it usually gets it cooling water from the smaller drain outlet on the cooler, although i dont think they started using dripless until 08
