I'm pretty ticked off. My Cummins 11.5 diesel generator is completely trashed and I have to replace. my boat is a 2015, and I bought in last year, thinking I shouldn't have to make these kinds of repairs/replace and a boat that's only 4 years old, 3 when i bought it. The boat was bought at a dealership, serviced at that dealership, traded back in, and sold to me from same dealership. boat had full service before i took ownership. I took the boat in 3 months ago (1 year after purchase) to the same dealership for an $11K service including the generator. 3 months later, total loss. something in the raw water side failed, spewing salt water all over, and corrosion cause lock up, i'm being told. I called Cummins and described to them what I'm being told, and they told me that scenario happens with improper maintenance.
