I saw this post below on a faceboook page. I recently purchased a 2014 R-27. The prior owner had it on a dock without shore power. I had it connected to shore power at my dock. I immediately noticed excessive corrosion on the running gear. I installed a galvanic isolator and spent a small fortune doing repairs. I thought it was something related to the marina being hot (although the marina ran a bunch of tests and assured me it was not the marina). They spent hours chekcing out to the tug. Has anyone else experienced this?
We were original owners who kept our 2021 RT29S inside a Certified Clean Marina saltwater boathouse year-round. Despite following recommended maintenance and having a diver check anodes and hull condition underwater every 3 months, we experienced excessive corrosion of trim tabs and prop even though the anodes were not excessively affected. The first trim tab corroded and fell off 16 months after we took possession. Our boathouse was checked by 3 different professionals and no stray A/C current was ever found!! RT recommended we add additional zinc to trim tabs. We added extra zinc, also paid RT to install a galvanic isolator just to be sure. Then, we lost the second trim tab and prop to corrosion. Our marina manager, then our mechanic, surveyed and found D/C current going through several wires on our boat that shouldn't have current - our boat was not grounded properly from the factory! Our mechanic told us faulty factory wiring caused a D/C leak resulting in the corrosion of trim tabs and prop. Our mechanic repaired a few other improperly wired RT boats and even spoken to RT representatives about it. Our diver has seen excessive corrosion recently in some late model RT's kept in year-round saltwater, despite performing recommended maintenance, adding additional zinc per RT representatives and no A/C current leak. The diver hasn’t seen this in other boats under similar conditions.
When we contacted RT explaining the latent defect and asked for reimbursement for excessive corrosion damage and repair of faulty wiring, they helped with some replacement parts, but were not helpful troubleshooting the defect. They didn’t seem interested in understanding the improper factory wiring issue. In the end RT refused to pay for repair and wiring defect damage. I just want others experiencing excessive corrosion to understand this could be the cause and urge them to get an electrical survey done.
