When i did my raw water pump last weekend it all went fine....then this weekend i started to think about how it went.

When i pulled the water input pipe off the bottom of the pump all was fine until it fell down..then water poured out...obvious as it was now below water level.

So i thought last night...what happened it if split under the engine....NO SEA COCK...WTF.

So if the pipe splits under the engine of comes off the through hull fitting the boat will sink and there is nothing i can do about it.

OK so it may never happen but i for one like to be able to seal off all my through hull fittings...!!!

I am amazed that this design was used.
 
I wouldn't have thought it was VP's responsibility to install/ensure installation of sea cocks.

But the whole engine and outdrive is a single thing made by VP..it's sold and bought as a complete package.

This means that the design is reliant upon a couple of jubilee clips to stop the boat sinking.

If it was a shaft drive boat then yes it would have standard through hull fittings that would not be VP's responsibility.
 
Swings and roundabouts: the water is drawn up through the leg, not a through hull fitting.
Adding a seacock would mean that the point of failure could then be the seacock! (these have corroded and fallen off too).

At least with the (very substantial) hose and jubilee clips, the critical parts are in somewhere accessible, where you can inspect/replace easily. Also, it's on the "suck" side of the water system, and the hose takes some wiggling to come free. But yes, if both jubilee clips fail, and someone wiggles the hose hard enough to come free and drop, you will sink. However, if you are that unlucky, you will probably get hit by a falling piano anyway.
 
Have never heard of boat sinking because that hose had split or detached.
Have heard of one sinking due to steering fork seals leaking but that would have taken for ever to fill boat

My apologies; only familiar with shaft drive.

D4/6 an accident waiting to happen, this sudden water ingress also happens when the short hose from the strainer to the fuel cooler fits off filling your engine room with vast quantities of the Solent all over your alternator and starter motor.
Servicing one is a matter or undo the 6 cover bolts and lift it up as a soon as you can. Yes a stupid idea but down to most stern drive applications not having any means of shutting off the supply in a hurry or any how.
 
not familiar with sterndrives, do all of them get their raw inlet through the leg or can they be converted to a through hull fitting?
just curious

cheers
