Sounds like you are due a flush then - Rob's how to makes it incredibly simple to follow.jumpjet231 wrote: ↑Fri Aug 03, 2018 7:07 am Brought this thread back from the dead. Do this if you haven't. I have now blown 2 ($90) hoses in 2 seasons. It's the hose the goes into the intercooler and of course it's a $90 special hose from Yanmar. The price went from $19 a year ago to $90. Mack Boring said I'm getting back pressure and recommended a Rydlyme wash. I didn't suspect anything was wrong because I always run around 180 deg. After the first hose split I just thought I had a old rotten hose.
a couple of things to be cautious with rydlyme though:
Make sure you're not wearing a watch - it stains stainless steel nicely!
Make sure you've not got a pair of Musto deck shoes on - They stain nicely!
Don't have your hoses too long or the bucket too big - it'll cost you more in product
Have a decent pump but not too powerful - I use a sump pump and if your connections aren't tight it will blow out.
If you get any of the product on your engine mounts, make sure you wash them immediately - the finish isn't galvanised but Zinc and Passivate, rydlyme eats zinc!
Good time to change your anodes after flushing - i machine my own anodes from rod so i can just screw in the new ones direct to the brass fittings.
Apart from all that - excellent product and does a good job, it was only on wednesday this week I flushed a friends yanmar in his albin with it, The stains have now polished out of my watch and my shoes are in the bin. I have a trade account with the UK distributor so it doesn't cost me the earth. I now have the flush down on service every two years.
