About Our Products

Raw water failure is the most common problem with marine engines. Within a short period of time several thousands of dollars of damage to engine or wet exhaust system can occur.

All our systems consist a fast acting, easy to install, thermal band sensor. The sensor quickly detects loss or restriction of raw cooling water well before engine over heats or damage to wet exhaust components. Two sizes of stainless steel band sensors fit wet exhaust hoses from 2″ to 10″ diameter. For larger diameters inquire. Standard tinned copper sensor cable is 10 ft long.
