That can really stink when a dealer closes. To cover my butt I purchased every available aftermarket warranty they offered at the time of purchase. We got coverage on the engines, drives and generator covered thru a Mercuiser package the rest from a warranty coverage company the dealer offered but if they go away they warranty is offered by other boat dealers in the area. We ended up with 6 years bow to stern on everything mechanical, electrical, cosmetic. I hope it's enough.
