Great looks, great value, works great and easy to install.
Great looking water heater for my Sea Ray 330 Express Cruiser. Cost less than the OEM water heater and had a great fit while the finish looks better than the original. It works great providing very hot water each use. I am very happy with this product.

Not a difficult install
Different mounting points and plumbing than the old seaward heater it replaced, but it wasn't that difficult to install. You may need to run new plumbing to make connection points reach but if you are at all mechanically inclined it really isn't a difficult job.

Product arrived ahead of schedule and was just what we needed. Slightly larger than the old tank but worked fine.
