I am reading with interest how some of you have "permanently" mounted plumbing into your sea strainers so that you can easily connect a dock side hose and flush your engines.

Can you provide links with photos to the trawler list or send photos directly to me?

I think it would be a great addition for me.. I have twin 120 lehmans...

Jim, Groco makes two bronze items that may be of interest to you.

One is a seacock that has a hose connection adaptor built in. Though pricey- depending on the size you need from around $350 - $550. I didn't include the prices for the seacocks that were larger than 2 inches, as I was crying so hard over their prices, I couldn't see to type.

The second item is an adaptor that screws onto the existing seacock, which also has a built-in hose connection adaptor. These run around $100 for the 3/4 - 1 inch size.

It wouldn't surprise me if Perko also had something similar.

One word of caution based on my experience: On my last boat the previous
owner had drilled and tapped into the top cover of Perko strainers for each
main engine and the generator and installed a fitting for a garden hose
connection. A very minor blow during usual engine maintenance broke off one
of these. Upon inspection, the thickness of the top cover allows only a
very short threaded segment for the installation. There was also some
dissimilar metal corrosion. All in all it appeared to be a disaster waiting
to happen. I took the rig out and put on new top covers. Your mileage may
vary.

This is a concern that I have also with tapping the lids of one of these
strainers. As a rule of thumb, there needs to be a minimum of 5 threads
engaged,on a fitting, to develop full strength.

An alternative would be to have the pipe nipple or adaptor brazed on and
copper or bronze nipples/adaptors could be used to minimize the dissimilar
metal concerns.

Then again, an cage of some sort can always be installed around the
fitting/strainer; but now maybe we are getting into that "is it worth it"
arena.
