This topic has been asked before but I still have the same questions.
On my previous smaller boat with a Yanmar
I never used anything during the 11 years of ownership
and never noted a problem other than replacing the exhaust elbow
. Now with a larger boat with a Volvo Penta
I have used Barnacle Buster once during 12 years but I don't see any change. Both boats were in salt water 365/year.
I don't know of any "independent" source that has actually completed a BEFORE-and-AFTER test and reported the findings. The test would be a lot of work
, first tearing the engine down to document the buildup then build the engine back up again, next to complete the flush, then to tear it down again to document the cleansing and lastly to put the engine back together again.
If anyone has found an "independent" documented study please share it with this forum. FWIW, I have shared this test request with Practical Sailor magazine many months ago but never received a reply which is not uncommon.
