Re: ITS plumbing question
This is what is on the other drive but the pump only plumbs into the first block pictured in post #19. The rubber lines with the factory bent steel fittins are the only lines running to the pump.
Now that you see what I have on the transom, will my sketched layout work?

Re: ITS plumbing question
Sorry I didn't get back sooner.
The basics of your sketch are right. The main difference is the pump connection block. If you can get the other pump connection block for the second drive, all you need is the right tee connections between them and the helm. If you find that it's too difficult or costly to get the second ITS pump connection block, you might want to consider taking off the one for the first drive and go with tees and check valves (already in the ITS pump connect block). Remember that the connections for the dual pump setups using the ITS are really the same, just where are the tee connections and check valves. Merc was trying to make it easier by keeping the standard pump and cooler lines normally used with the internal cable steering.

Re: ITS plumbing question
Are you saying with an additional connection block, my sktched layout works and without one is doesn't?
Adding a connection block to the second transom plate doesn't sound difficult, would each block have it's own pump and reservoir?
Would i just leave the two lines now connecting the blocks to keep the system in sync?

Re: ITS plumbing question
Here is a diagram of what a dual pump ITS can look like. I am not much of an artist. I did forget the filter(s) that should go between the ITS block and the tee on the output line from the ITS block to the tee. Hope this clarifies what I am talking about. I believe there is a drawing of this in the ITS installation manual, although you probably didn't get it from the boat builder.

Re: ITS plumbing question
Actually, that is a pretty good sketch. No the builder di not give me a manual. Do you have the part # for the second connection block I need?
Do you sell those?
BTW; Thanks :drink

Re: ITS plumbing question
I would give your boat builder a call (Fountain?) and see if they can send you the block. They had to remove it, and probably remove one every time they do a twin ITS install. They probably throw them away! I will try to find the part#, but I think it's for the complete assembly, not just the part you want.

Re: ITS plumbing question
Seeing how the two connection blocks are connected, is there a way to keep the helm lines as they are and route the pump lines like your sketch?
(I tried e-mailing this question)
Note how the pump and helm lines are on the starboard connection block and the blue #8 lines connecto over to the port block, If possible I would like to leave the helm lines alone.

Re: ITS plumbing question
You could get some tees that go into the bottom of the stbd pump connect block to get the lines over to the port pump connect block. What might be simpler is to tee the P & T lines somewhere between Merc pump connect blocks and the helm, then go from the tees to each individual block. (That's what my sketch shows). It does get a little crowded back there. The main thing that the Merc pump/cooler connect block does is let you keep the standard pump and cooler lines as well as incorporate the check valves.
From the pictures it looks like you have reuseable hose ends. That might make it easier to shorten the helm P & T lines to separate tees. If you are very careful you could make it look very tidy. I would get someone involved familiar with hydraulic lines. You don't want to make a mess or worse.
