A good maintenance program can help avoid unwanted problems:

      Upon completion of the initial dive service with no established record of zinc burn rate history, we return in 3 months to evaluate conditions and determine a proper time frame from there.  We replace zincs when they are approximately 50% intact to avoid troubles with galvanic corrosion and ensure that shaft zincs are not burning so low that they become loose with the potential to cause damage.

Hull cleanings are often performed with each zinc replacement schedule with additional hull cleanings when requested. We always clean the running gear (shafts, propellers, struts,  trimtabs, bow and stern thrusters, depth sounder transducers, thru-hulls and intakes and knot meters).  Often seagrowth on propellers and  running gear in general may inhibit the performance of the boat.  We also assess paint condition and look for any signs of damage or blisters. 

Once the schedule is determined we send an e-mail alert one week prior to each needed service to ensure we are all on the same page avoiding any surprises and so the owner always knows what’s going on with their boat.  Once the dive is completed, we report  in via phone and to make our recommendations.  Each invoice is complete with a written report of the job done and conditions below the waterline.  We always note when the next service is due.  (We can send invoices by direct mail, e-mail or both ) and attach High Quality Underwater PHOTOS for client’s review of before and after service performed and conditions below the waterline.

 

"Jorge was completely right in both his observation as to the damage and his recommendation not to run her. I had the boat towed to Seaview in Shilshole, with the shaft locked so it couldn't turn. She did in fact have both a bent strut and a bent shaft. Hate to think of what additional damage I might have caused if I had tried to run her to Shilshole, or even to the travelift at Edmonds. I would and will recommend you folks without reservation to anyone needing a diver. Thanks."
