Re: Engine clean out
What engine? Raw water cooled or through a heat exchanger?

Re: Engine clean out
Might also check for zincs in the engine and change those... Not sure on that engine but Yanmars have up to 3 zincs on RWCs

In addition to the foregoing, recirculate SaltAway through your system. Counter flow: in the discharge end, out the input end.

Re: Engine clean out
Using Salt Away. Highly recommended from a local yard. Figure it can't hurt and is easy enough to do when ever the boat is laid up for a while.

Re: Engine clean out
Phosphoric acid. Just did this on my 43' Bene. Home Depot sells it as an etch and prep in the paint dept. strong stuff Dissolves scale and barnacles.

Did you let it sit in the engine for any length of time or just pumped it through. ?

Re: Engine clean out
I used a pump in a bucket and recirculated it through the raw water side from the heat exchanger intake to the hose going back into the exhaust rider. Then I filled the hose from the through hull from above the water line and closed the seacock to complete the raw water clean out. Then I diluted it 50% with water and flushed the engine. Drain and fill run engine till hot. Repeat until clear.

I would be very circumspect about using an etching compound on the water chambers which need be maintained as smooth as reasonably possible to prevent over rapid build up of salt/silt/scale deposits and an environment conducive to marine growth when the engine isn't running (which is most of the time). The Barnacle Buster/RydLyme and SaltAway are effective at cleaning without the danger eroding the surfaces of the galleries. The minor cost savings of using aggressive alternatives may be a case of Penny Wise/Pound Foolish IMHO.

Re: Engine clean out
Barnacle Buster etc are phosphoric acid. Just more expensive.

Humm... Right you are. I wonder about the relative concentrations but the Material Safety Data for the product certainly confirms your information so I stand corrected/better informed.

Re: Engine clean out
Yeah. I researched this prior to going with the Home Depot stuff. It works great.

Re: Engine clean out
I've never done this to my engine(s), but sounds like something I should.
What sort of pump did you use?
Thanks!
