outboard engine cooling system blockage - help?

[kamau]

I am experiencing recurring blockage of the cooling system due to salt crystal buildup. Does anyone know of any solvents to use periodically to prevent this?
I am already rinsing the engine regularly in fresh water.

I had a similar problem that was caused by some small shell fragments which would flip around and block the tattle-tale outlet. I pulled the hose off and cleaned it out and it was all set. I doub't your problem is from salt build-up if you rinse your motor with fresh water. You may have blockage but it is most likely from debris in the cooling system.

Thanks for the response. I have had to go in there and scoop out the incrusted salt in the past, and assumed that it is the same thing. I will check it out.

On Ship Shape Tv the other night they talked about solving that problem, they said rinsing in fresh water was not enough. I didn't watch the whole show, so I didn't see that part, look up their web site, I'm sure you will be able to find out how to solve the problem. Don
