SureSeal crossover hose

[ttmott]

In 2010 the Tides SureSeal assemblies were replaced by the previous owners. The replacements (also SureSeals) only have one port for the cooling water connection. I would like to add a crossover which would normally connect to a second port which doesn't exist. Is it possible to tee the crossover intothe primary cooling lines? And, if that's possible would check valves be required on the primary lines before the tees?

thanks in advance!

Try again for some help??

You might want to pm Frank Webster. This guy knows everything!!! And if you're reading this Frank, I mean that in the most sincere way:thumbsup:

Machining a second port for the crossover line is relatively simple - but that option requires pulling the shafts back a ways, removing the Sureseal assemblies, and then drilling and tapping the second port.

As you mentioned, the other option is to simply tee off the existing port, and add a crossover line. No check valve is required, but you need to make sure you use the appropriate size fittings and hoses such that you don't introduce a flow restriction anywhere in the system.

Thanks! I considered the machining also and may still do that but the next haul out isn't planned until fall 2013 and we have a couple of Bahamas trips planned before. The crossover I think is necessary before getting too far from service. Also I really appreciate the input and will move forward with the tie-in to the hoses; I think I'll do the check valves regardless however.

My boat has the crossover lines and does not have a check valve I think that mite restrict the flow

Ok - I did the crossover hose which I used the same hose size as the primary's. I also did not install check valves. As it ends up much of the water bypasses up through the down engine exhaust manifold which is not desirable by any rational thinking. This showed during a test where I removed the exhaust riser hose from the down engine and put a bucket below it. I will be installing a couple of swing check valves - these 1/2" bronze 125 class check valves http://www.mcmaster.com/#standard-check-valves/=ksmagl

Why do you want to install check valves? This is not a standard installation as far as I have seen. Mine just have a tee on each side.

You might want to take another look at that arrangement.... What I found was the water prioritized up the hose and out the engine's ( the off engine) exhaust riser rather than all the water thought the seal assemblies. Without the check valves water would be reduced at both the seal assemblies with a down engine. Found this out by test.
