I added a NexGen generator to our then new-to-us, 2015 Cutwater 28. This was in 2017 and the total bill was about $15,000.00. The install was very professionally done in Bellingham, Washington using the same components and parts used by the factory, at my insistence. Two of the techs were actually former Fluid Motion employees. I was very happy with the work, but it’s not cheap. I would highly recommend taking a look at using the NexGen in lieu of the Mase. NexGen has more capacity, quieter, very good parts availability, and good reputation for reliability. It also utilizes a bulletproof Kubota motor. All just my opinion, so take that for what it’s worth... :-}
