Scott, a typo?
I agree about the blue hose on the FW side. But I've also seen it used on the saltwater side, inc on my boat when Slane's installed my engines, and it's holding up fine. I think it IS made for that.

It really is alfagoma. made in Italy and great to work with. I use it on Seawater all the time. Its nicer than the shields and holds up.

Re: Engine water hose What type?
Where do you buy it? I can look it up etc but since you are in the business it would be useful to know where you get it.

Re: Engine water hose What type?
while we are on the topic of hoses, what do ya'll think is the best hose to use for a/c water? i need 1 1/4 from seacock to strainer, to pump, and 1 inch from pump to manifold. i am making a pvc manifold like spcoolin suggested, and will be changing all hoses while i'm in there

The black hoses have less growth in my experience. I usually use the wire reinforced Alfagoma on the intake and the black water hose on the output of the pump.

Re: Engine water hose What type?
On my boat, all the long salt water runs are black exhaust hose, ditto including for the AC. You need the rigidity and it does seem that it breed less growth, compared to what we saw coming out of the Ac units themselves when acid cleaning. No empirical evidence other than observing when I switched it out for the right size from a POs mis-install.I just replaced about 3 ft section on the generator outlet with some of the Vetus gray hose, sounds like what Scott is talking about. It went around a sharp bend much better than the old hose which had developed a kink.
On the main engines, silicone is used for all the short connections, including some seawater in and out of the intercoolers; the two old school Detroit mechanics I use both were very particular about using silicone there, and installing new ones at about the 5 year mark at the nearest scheduled intercooler cleaning. When the PO had the engines "done", using a legendary guy (since deceased) from Central in Landover MD. So make it three. Hardly "some guys behind the counter".Last edited by GJH; 12-26-2012 at 11:19 AM.
