Descaling Motor Flush

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.

Re: Descaling Motor Flush

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.

Re: Descaling Motor Flush

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.

Re: Descaling Motor Flush

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.
