I bought my 1998, 40’ Bayliner with twin 330 HP Cummins three years ago, and all this time I noticed the starboard engine was not running as well as the port. The survey did not include a diagnostic on the cooling system, therefore I had no idea of the true temperatures that the engines were running at, being the gauges are not that accurate.
I brought in three different mechanics to give me a quote on servicing the entire cooling system. One mechanic confirmed the problem by taking off the end cap of the starboard heat exchanger, which made the problem apparent. The heat exchanger was 90% plugged with marine growth. The quotes ranged from 10,000-15,000 to service all the components that re serviced by the raw water cooling systems.

I bought the flushing equipment and went to work and the results were amazing. It completely cleaned my entire cooling systems of marine growth including the fuel cooler (see before and after pictures). Shortly thereafter Barnacle Flush was born!
