Flush extension?

Hi
I just repowered with twin honda 225s. Picking it up next week..
I have a bad back and have trouble bending down to reach the flush port. On my old engines, I attached a 3' hose to the flush attachments, with a shut off valve / quick disconnect on the other end which was attached to the railing on my transom. Made it simple to flush. When it was disconnected from the fresh water hose, I shut off the valve.
1. Is there any problem doing this? Wouldn't want to hurt my new engines.
2. I would like to make it look nicer. I am thinking maybe run the hoses through the transom and connect to a quick disconnect on the gunwale. Could I get away with one disconnect and put a Y on it to supply both engine at the same time? (I have good water pressure)? Or should I have a valve that can direct the water to one or the other or closed? Is it important that it closes off when not in use?

BTW the boat is a worldcat 27te
thanks
 
I have seen several people on this forum that have do just as you would like. Hopefully,
Chawk or one of the others will jump in to give their opinion and real life experience.

I do not know of any reason, why it will harm the engines. "Theoretically", you should not have to shut it off while the engine is running, due to a check valve where the hose connects to the block. However, I would recommend that you do shut it off, just as a factor of safety. If the check valve gets stuck open from salt or debris, it could affect the water pressure inside the engine, possibly causing an overheat.

Just my thoughts....

Bigfoot. Send me an e-mail at [email protected] and I will send you pictures and a write up of how I rigged mine. I rigged it on my 07 BF225 in the summer of 08 and no problems at all. You if you use a regular garden hose quick disconnect, you will need to replace them every couple of years unless you get the solid brass ones. And, the hose will need to be replaced periodically because of sun exposure. Very simple to do.

I don't think a Y connection is a good idea. When flushing the engine through the flush port, the water is actually traveling in a different way than normal, and it needs a good bit of pressure to get up into all the upper part of the water jacket.
 
My flush attachment does have a Y connection, but you can shut off one side or the other. It takes a little longer to do it this way, but it assures that the outboard is getting enough water
