Yanmar lp315 water intake ?

[JohnCranston]

I need to order a pair of Groco external sea strainer today per Capt Pats tip section. Does anyone know what diamater I need? The mechanic is in the field with the Yanmar manual.
Much thanks.

John,

The engine raw water intake is 1 7/8". The through hull should be a 2" with a FULL FLOW 2" ball cock valve. A standard 2" ball valve only has a 1 1/2" actual opening...

The Groco strainers should be over sized to fit a 3" port. This over sizing will assure that you have adequite water supply through the strainer, even under less than optimum conditions. Be sure to toe in the leading edges of the strainer to maximize water flow over the strainer surface.

Thanks as always, Capt. Pat. What's a good sea cock for my application? Is there a good place to buy everything that I'm going to need? Sorry about the dumb questions.
Thanks again.

Blackburn Marine or Wilco Supply. Both local to you at one house or another.

Ernest,
I don't have an account with either of those. Only one with West Marine Port Supply.Any help?
Thanks.

Wilco sells over the counter to any fool that can drag their butt to the location.

Blackburn sold to me as well, but over the phone.

Grainger will sell over the counter just the same.

What do you mean by account? If you are not seeking credit, why would you need an account?

John: The Groco full port ball valve seacock is the best I've ever seen. Pricey, but excellent. I have one of those and one Apollo (my old standby brand). The Groco is hands down better. West sells them, but they are pricey! I have the SBV.

Rawleigh,
Man, that's what I needed. I appreciate it, as always, great info!

I also like that 6 port fuel valve that handles both the suction and return lines for diesels or F/I gassers!
