Forums, Internal Fixtures and Fittings, Raw water intake

Hi,

My raw water intake and combined strainer is leaking (Stuart I believe). Does anyone have a recommendation for a replacement and knowledge of the hole diameter.

Hi, are you sure it is not just needing a service, if it is the same as mine the valve is cone shaped (a bit like the Blakes seacocks) and can be taken apart and regressed. Worth a try if you have not already done this.

I’m not aware if this type of combined seacock and strainer is still available so you may need to go for a separate seacock and plastic strainer in the engine bay.

Hi Bob
I replaced my stuart a couple of years ago, it dripped (slowly) and I could not solve it. I was also told it did not have a large enough flow for my engine cooling. I replaced it with a blakes. It required the hole filling in and then re-boring because the blakes needed a smaller diameter. Also, the stuart had three securing bolts and the Blakes has four. I still have the old stuart and if I can find it tomorrow will measure the hull hole required.
Regards
Tim

Hi Bob
Found old Stuart seacock, the hole in the base is 28mm diameter. It then drops down to 9.2mm internal diameter, this is possibly why I was told it didn’t meet the engines cooling requirements.
I replaced it with a 3/4" blakes which requires a 22mm hull hole.
