Washdown for SC20SF

Jon G · #1 05-25-2003, 09:39 PM

Nick what boat are you talking about? There are a few differant variations out there depending on the year or model. The basic principal is you need to tee of a seacock thats connected to a scoop thru hull for the supply then you just need to apply that to your boat and your all set. I've got room for one I just havn't gotten around to installinig one yet. Are you talking about a 20 or a 23?

Opps I din't read the title of the post. I have the same boat, more that likely you have a thru hull with a seacock on it in the bait well in the floor I would tie in to that for the pick up and put the pump in the bilge area of you have the room. I'm asuming that your bait well is in the floor and not on the transom what year is it?

Any suggestions on how to install and route a washdown system would be appreciated.

Thanks for the reply. The boat is a 1987 and the livewell is in the floor behind the center console seat. From what your saying I think you are suggesting I run the water intake out the drain of the livewell. If so I would then have to drill thru the livewell for access to the pump in the bilge. I was trying to avoid drilling thru the livewell to avoid taking in any more water into the bige than necessary.

Nick you will need to thru hull fitting scoop thru the hull of the boat near the stern. You want to mount it as far back and as close to the center line as you can. This way it will still work as your running. Be sure to install a shut off valve. The pump itself can be mounted anywhere. Be sure to mount it where it can be easy to get to when it needs service, and be sure its out of the weather.

Nick I'm not familiar with the layout of the newer boats. I have a truhull in my bait well that runs right thru the hull. This is where I would tie in my pick up for the pump in to. Then like Joe says the pump can go anywhere. You do need a scoop thru hull and a good seacock for a shut off if you should break a hose. I'm using the old washdown system for the time being(bucket [img]images/icons/rolleyes.gif[/img] )

Does the scoop type of water intake detract from performance? Can it affect the transducer? Can you use a non-scoop thru-hull? Finally, where exactly would you put it?

The scoop would not take away from performance. It could foul up your transducer reading and should be mounted away from it. You can use a plain thru hull but it will not work right if the boat is moving.

I thought about the regular through-hull. Considering the fishing I'm likely to do in the next couple of years, I don't see me making a mess that requires a washdown underway. Unless, of course, you drink too much on the cocktail cruise and hurl.

As previously discussed, I sealed every through-hull fitting except the rear drain plug. How big of a tank for water would make it worth installing and foregoing the future leaker.

Reminding you that we use the 23 only in fresh water. Comments?

Thanks guys for all the great info. I went thru the transom well thru hull fitting and plumbed to the center console. Then mounted the pump to the console floor and wired it to a seperate switch. Everything worked out great and it's pumping fine.
So, I have a one foot length of hose hanging down the transom for a pickup. Will screw it down in the future with a stainless clamp.
