I used a 'Sea Flush' funnel to accomplish this task. We noticed lots of gunk coming out of the forward thru hull so I want to descale and flush the system. There is a youtube video (attached) describing the process utilizing their system in conjunction with a product called 'Barnacle Buster'. Have any of you ever done this? I am thinking the system will run more efficiently when cleaned. Has anyone had experience using the product called 'Barnacle Buster' as described in the video? Do you have any experience and tips for getting this job done with or without this system? Thanks.

Re: Flushing the A/C Unit
There is one thing mentioned in the video that I would approach with caution; he instructs you to pinch the line after the strainer however most applications usually use hoses that incorporate a wire or plastic winding within the hose. These types of hoses should never be pinched in that manner. If you're performing this task in the water, then you need to purge the water in the intake side but it's better to remove the hose from the output side of the strainer and block the port with your hand while you blow out the intake side, you'll need to close, open, then close the seacock again as required to accomplish this. If you're doing this out of the water and the line from the seacock to the strainer is installed correctly, it should be a down hill run and empty on its own. if that's the case, no need to purge the intake side or pinch a hose, you'll just have to drain the strainer by pulling the drain plug.

Re: Flushing the A/C Unit
The method shown also shows the coil or anything above that for that matter will drain out due to the exit through hull being lower meaning the product does not sit and desolve the scale/crude over time like it is suppose to. I much prefer to circulate the product via a pail and run it for 20 mins or so. Does require some hose pulling, a pump and access but a better method for sure.
Here is a rather primitive yet effective way of doing what I mentioned above.
