I’ve just spent over $3,000 per motor to have my heat exchangers cleaned, do I now need to install these flushing devices?

Yes, cleaning heat exchangers which have become clogged with salt, can be very expensive, and not just in monetary terms. If you rely on your boat to make your living (eg. charter boat, water taxi, pilot boat, etc), then you don’t want the boat out of the water any more than is absolutely necessary. Now, with Adit Marine’s fresh water flushing devices, your boat’s down time can be reduced.
By regularly flushing your engines with fresh water at the end of each boat trip, you will be keeping the build up of salt in your heat exchangers to a minimum.
