Ordered the factory extension the weekend I agreed to purchase the boat back in March.. They said 6-8 weeks being its custom made per order.. Was super excited when Fed Ex showed up on Saturday with it.. Glad I brought the boat back from campground Friday when I was up at the lake..
Deck extension is freaking huge for the 621.. However I will say I was shocked that it did not come with the seat pedestal thru brackets installed or the L brackets to fasten to side and secure it in place.. I would think all the seat holes are in same location coming out of the factory.. I could see someone that is not handy or have hole saw, drill and experience having to take it to the dealer to have done..
