Blocked intake

[billyfish]

Newtown creek, lots of sh--ty green weed pulled into the engine raw water pipe which has a 90° bend on entrance, is there a simple bit to go into the hole on the out side to make it into quarters so I th at it can't make a bung,,,if you see what I mean

Mine has a domed cage sitting over the intake pipe.

What strainer do you have? Can you take the lid off and use a dinghy pump to eject the offending matter?

 

[billyfish]

Tried the pump. No good . eventually had to take it all apart and poke it out. 3/4 skin fitting straight onto a 90 then lever valve. Domed cage is what it needs

 

[penfold]

Any prospect of getting rid of the 90 bend? They cause blockages so much.

 

[billyfish]

Thats what I want to do. But space is limited, going to look at a new position for it this winter

Domed cage is what it needs

If you are thinking of that on the outside then not recommended. They are far more easily blocked and even more difficult to clear. Straight through is the best option.

Whoever designed that 90° bend in the system needs keelhauled!

It should be as easy as removing the jubilee clips, pulling the hose off the thru hull, opening the valve and poking a screwdriver through.

Scandinavian's . Which surprised me as well

We had an inlet blockage of very fine green weed some seasons ago off Langstone Harbour.

The old screwdriver was a non starter-it just moved a couple of strands at a time.

First mate suggested the spare insert for our posh corkscrew.

This worked a treat. The hose was removed, the blockage still stopped the water from blowing it clear.

Once cleared with the corkscrew insert I turned the seacock on and the resulting jet of water blew the rest out.

It would have been a far different matter with a 90 degree bend

Change the 90 degree bend for a tee with a plug in the vertical leg of the tee.

You will be able to remove the plug to clear any weed

A tee, brilliant
