Outstanding product

They work

This is the 3rd product I have used.
The other 2 were good, but stopped selling in UK.
Expensive to buy a 3rd hose mixer.
This does work ...but at 8 tablets each time it is expensive.

After issues with initial courier arrangements, Boatworld sorted it all out!

The order was placed at the end of last month, but having been let down by the initial courier, on then re- contacting Boatworld a quick alternative was arranged, and it turned up today! ☺️

blue Thro de salt tablets

Well, not really sure. After taking the thermostats out of my Yamaha 40hp 4 stroke outboard there was blue crystals behind the thermostats, but no salt seen. So do they works, possibly. But I always flush to extreme.
