I'm looking for some creative ideas on how to clean the mussels from my inboard cruiser water thru-hull intakes while the boat remains in the water. The intakes for both engines and the genset are as in the attached photo with grates over them.
My current plan is to have one person in the water (SCUBA) and one inside the boat at the thru hull when doing this job.
My primary question is "how best to clean under/inside the grates of the thru-hull that are not easily scraped with a putty knife?" My current plan is to use a rifle barrel cleaning brush. Any other thoughts? This will be a semi-annual 'to-do' item from this year forward with the mussel problems accelerating.
Thoughts appreciated, Doug
