Raw water hose

I'm still stumped by this one.
It is a Volvo Penta Model 2002.

The hose does not seem to reach the raw water through hull.
Is there supposed to be a filter there that someone has removed?
Maybe an elbow?

I can't find any pictures that make sense.
Maybe I could just stretch the host and make it reach but that doesn't seem likely either?

Re: Raw water hose

Most likely the raw water strainer was removed. The strainer is important as it keeps bits of sea debris out of your engine. You should install a new one before running your engine.

Re: Raw water hose

kinda looks like a hose barb (hard to tell) on the valve... maybe someone cut the hose? Also likely that valve is not screwed onto the thruhull by more than a turn or two so you might not want to put much strain on that as it is...

Re: Raw water hose

If the hose is too short replace it. There should be a strainer installed above the waterline so it can be cleared without a flood.

Re: Raw water hose

I bet if you look you'll find where the screws went that held the strainer on the wall there. I would install a strainer and get another piece of hose and king nipple to go from the through hull to the strainer and a king nipple to attach the hose you have to the strainer. Bummer, the good strainers aren't cheap.

Not all sea strainers are/were installed above the waterline. They should be.

That being said, there should be a sea strainer in place.

Re: Raw water hose

A strainer like this isn't very expensive.

Re: Raw water hose

I have some evidence that the hose was cut. There are no clamp marks.
That would explain it being short.
I had to cut the other end to remove it so I'm not surprised it was a problem.
The hose might be imperial and the barbs metric. They seem to be a very very tight fit.

Re: Raw water hose

Strainer was removed because someone didn't winterize the boat and it split open?

If the boat was built in France it could be metric - doubtful if built in Carolina though.
