Any views on Salt Dissolving tablets for fresh water flush of outboard?

[Egret]

Any views on purpose made Salt Dissolving tablets for annual fresh water flush of outboard? Came with the boat. Go in a little blue canister connected to the flushing hose - Do they give a gentle clean out or are they more likely to cause crud to detach and block the water ways in the engine?

I don't think they are very strong. It's more to dispel the salty water to help prevent build up and corrosion.
Rydlyme would properly attack existing build up.
I use anti salt as often as possible in my outboards and Jetski.

I agree with Boaty_Pete. If you have them, use them in any case as it won’t damage the internal components. A good practice is alway to flush an outboard for at least 15 minutes with fresh water after every use.
Rydlyme is a top product but can be expensive. Maybe use it once a year when the boat is on the yard. I watch a channel called Born Again Boating (please see below ) that has all sort of videos related to outboards and more.

Rydlyme is dilute hcl with a high price tag. However hcl dissolves aluminium most effectively and given outboards are aluminium I would avoid any hcl based product.

Dont washing powders have anti-lime scale, chelating agents, anti-corrosion ingredients and such?

Planning to use some to flush my inboard in the next few days, so if theres a good reason not to I'd like to know what it is.

Laundry powders don't have much chemistry to counter calcium build-up. The better dish washing detergents have both lime scale and corrosion inhibitors.

I'd have thought both clothes and dish washing machines would require corrosion protection?

You can get Furnox in various forms ... for outboards - use the one made for Alloy / Aluminium .....

Furnox is the chemical put into Domestic boiler systems (Central Heating). Its far cheaper than 'Marine' products !!
