No it's a proper bronze one with the strainer and butterfly nuts on top. Also the same on Haydns Princess 35, just below the water line.

Re: Fabulous experiments
Hm, I must say this is strange, if as you says the height of the strainer is below the water level. But the question that nobody has asked is - how the hell did you find out, hm?
Did you just think hehe i will just try and see if the boat sinks - no danger of the water pressure overcoming me and despite argh confusion of massive hole with water splooshing about and lectric, i will definitely be able to close it? Or were you a bit drunk and decided that you fancied a look at the raw water strainers before going to bed? Or what?
Either way, your ability to defy the law of physics if something you should not waste. Try whacking a big hole in the bottom of the boat with an axe. Normally, this would make sink it BUT given that the sea didn't come in with the seacocks open, it stands to reason that it won't sink at all. Widen it out and you will have a nice swimming pool.
I wonder if perhaps- are you aground? Or are the lines really very very tight and holding you up? Or is the boat upside down?
Actually, I spect the boat is out of the water. That might explain it. Most people would check to see if they are aground or in slings by looking carefully over the side, because they might hurt themselves if they land on the ground twenty feet below. But don't take my word for it - and remeber - the seacock-opening caper went fine didn't it? So, it will probably be ok to chuck yourself overboard, and if there is some water you won't get wet, somehow, or if there isn't you will float down nicely, I bet. Then come back and tell us about it again.

Re: Fabulous experiments
Okay, so If I start taking on water, in my unsinkable boat, I will just hack a great big hole in the bottom and all the water will run out!!!
The strainer is above the water line, but the water runs out to about 3-4 inches above the Seacock (3-4 inches above the seacock is below the water line)

Re: Fabulous experiments
Oh no it isn't. Whatever the level of the water in the pipe, that's the water line. Unlesss your engineroom is somehow at a higher pressure than the outside world. Anyway, how do you know it's at a different height? Have you already done the hole? Try a bigger one further up the side, at about the level where you think should be air, not water.
You stil haven't admitted how you found this out.

Re: Fabulous experiments
HAA, you have finally caught on to the odd bit, the water seems to drain down to way below the water line, allthough this is impossible (and I know that!!) it somehow does it.
How did I find this out? Well erm you see it was like this...... One day..... I .....erm.......I'll tell you another time!

Re: seacocks
Seacocks are manual valves that you can either open or shut.
On mooses boat, and many others, they take in water from the sea to cool the engine. An impeller sucks it in. The seawater indirectly cools the engine, by cooling some coolant, and that wizzes round the engine to keep it about 85 degrees C. The coolant anyway.
This means there is a big hole in the bottom of the boat - from which (internally) there's a pipe going towards the engine with all that seawater. If the pipe breaks, it might sink the boat, cos depending on where the pipe broke a load of seawater would rush in. So, the very first fitting on any hole in the hull is a seacock - a valve to shut the hole if there is any problem. There are (or should be) seacocks on every single hole in the hull, for waste water, showers, everything.
Many people say you should shut all the seacocks every time you leave the boat. But others say that means that if there's a problem with your boat or a neighbour, or if you need work done, then if any marina man or engineer starts yer engine, they will bust it cos no coolant. Or, you will cos you will forget about the shut seacocks.
Now, moose has decided that if he opens his raw (ie sea) water strainer (like a big filter thing) and opens the seacock, the water runs back out. Which it would do, if the strainer (to keep out fish and seaweed) is at a higher level in the engineroom than the sea level outside. But he says it isn't, and the seawater in the pipe runs back down to about four inches BELOW sea level. Strange, but true. Or perhaps, total b@ll*cks and untrue.

Re: seacocks
Thanks tcm, I understand that all boats are cooled by the water they sit in, I thought that the water was sucked in through the outdrive leg, which is where i thought the impeller was situated, the water was then pumped round the leg then back out through the exhaust.Maybe i'm right and maybe i'm getting confused with bigger boats, and its only boats that are shaft driven that have seacocks? so if this is the case then when you buy something like a large Sealine and they offer the option off either shaft drive or stern drive, then they have completely different cooling systems, then?
I can understand why some people would shut them when they are not there, as i would presume that a bilge pump would not be able too cope with such a large permanent flow of water.
Confused..
