How To Clean Deposits In Salt Water Cooled Engine

• #1

Being a new member/sponsor just not having much to add in the way of diving experience, I thought some of you might be interested in this.

I conducted a little test yesterday that some of you might be interested in.

The exam was to meet the effectiveness of using vinegar to remove salt and scale deposits from a marine engine. We know that you lot tin can purchase common salt removing products such as Common salt Abroad and Salt-10 only I was a laic that vinegar would be just as effective.
The test subject is a salt water used 1994 Yamaha 130 V4 with unknown history of maintenance until well-nigh xviii months ago. At that time I purchased the engine and take used it almost fourscore% in salt and flushed thoroughly after every use. I recently ran the boat for most 50 miles in fresh water and so a overnice salt water run well-nigh a week ago.

I filled a big heavy duty garbage tin can almost ii/iii full with water and added 4 gallons of vinegar. The boat has a nosecone and uses a transom mounted water pickup so I disconnected the house, primed the pump, and dropped it into the water then lowered the lower unit of measurement as far as possible.

Yeah, that is a little grass stuck in the t-stats. Last time out I ran through a lot of floating grass in Charlotte Harbor that gets pickup up past my transom mountain pickup.

This is my little go fast tunnel hull. I too have a Fountain CC with a 225 Opti and did the same handling but did not accept pics.

These are pics of the test subject, thermostats, and housings prior to the test.

I ran the motor for about twenty minutes and then the temp started to creep upwardly due the water in the garbage can getting hot. I checked one thermostat and found about of the common salt gone

These are before and after pics of the same t-stat later on xx minutes

I continued to run the gunkhole on and off all day for possibly an i-1/2 hr full but didnt see whole lot of improvment. When I finished I pulled information technology autonomously once again and this is the result. The scale on the thermostats simply wiped off leaving the shiny surface in the second pic.

When I started, the scale (non common salt) buildup was hard equally fe. I noticed when I was washed it was very soft...kind of gooey. There was no way I could have removed information technology prior to this test merely after, nigh of information technology easily came out with a spray from a garden hose and I scooped some out with a screwdrive. I remember going for a skillful run in the boat right later this treatment would remove a lot of that loosened cloth that merely didnt get washed away idleing in a saucepan.
This is the t-stat housing before the examination and after a skilful squirt with a hose and a little cleaning.

Heres some video I took earlier and after. I saw a small-scale comeback in water pressure level just I wouldnt put a lot of weight on that which could be acquired by a small alter in how it was idling or the water source.

Overall, I am completely convinced vinegar does a corking job of removing salt and even loosens the scale buildup inside the cooling system of a fresh water cooled engine. This will now be a regular function of my maintenance program. Every bit far as it comparing to table salt removing products sold to boaters, I deceit imagine they would work any better. The salt is nigh completely gone which is the goal IMO.

A few words of caution:
1. Remove your prop to avoid a potential accident.
2. The water GETS HOT.
3. Dont go out your boat idleing unattended.

Here is the garbage can. The h2o started clear. When it all settles, I will pour off the top and post pics of what came out.

Thats it in a nutshell...
I will pull it apart again after I run the boat the next fourth dimension and see of whatsoever of the loosened scale is removed.

Thank you.
Another tip that has worked very well for me is to use vinegar when washing the boat at the finish of the day. I use a "punch-a-sprayer" hose cease blazon attachment used for gardening. I fill it one/3 with inexpensive Blueish Coral car soap and 1/3 with vinegar. Set the punch to where yous simply start to get some suds when spraying down the boat. It works VERY well for removing salt from the boat. In that location is a huge deviation in the amount of table salt on my black motor cowlings if I exercise this vs. just spraying them down with h2o solitary. I spray the whole gunkhole, t-peak to bottom and then brush what needs it. I also have hot water plumbing exterior which also helps remove salt.
The fishing boat is a 2003 and I dont call back youll detect a cleaner viii year old salt water gunkhole in Florida. This stuff is too expensive non to take of!
Do you lot guys use anything except directly h2o for cleaning your swoop gear afterward a salt water dive?

PS. Actually surprised how petty traffic this section of the forum sees. Last new thread was in May!
