Descaling Motor Flush

[PedroPV]

Has anyone already tried to flesh the motor with "Starbrite descaling motor flush" Descaling Motor Flush ?
I fear it may damage some parts of the motor, like seals and gaskets.

I've only used Barnacle Buster and Rydlyme on mains, genset, and ACs, both with success. Salt-Away through the outboard worked, once I started using it more often.

look up or request the MSDS sheet. Then check what the active chemicals are. If necessary give information in this thread to get other opinions.

As long as you descale as directed and then properly flush the descaler out of the system you won't have a problem. Don't let it sit or circulated for longer than necessary time.

I use Rydlyme because I can legally dump it over the side when done.

Had an overheating issue with my Yanmar 1gm10. Replaced every external part I could but the problem was still there.

I did a 2 hour circulating flush with Rydlyme and 2 hours of fresh water. Bingo problem gone.

I set up a 5gal bucket with a bulge pump wired in. Took out the thermostat and impeller and ran a Jose from the bilge pump to the water pump through the
Motor and out the exhaust cooling nipple
Of the thermostat housing back into the bucket.

Ran it for a solid 2 hours.

Finished and then ran clean water through the system for another two hours. Worked great. Highly recommend it.
