If going with a new rode, start from your anchor and spec back to the windlass.
Is the anchor you have the one you want for the size of the boat and your cruising area?
If so, then go to the swivel or shackle that is a strong as the holding power of the anchor, then the grade and size of the chain and rode, and finally to the windlass which will handle that system.
I am also using a Maxwell 10-8 that I replaced an inadequate Lewmar with. It was set for 5/16 chain, so I have 300ft of that and 200 ft of 5/8 Yale 8 brait to an 80 lb Manson Supreme anchor.
We are a 40 ft Cheoy Lee at 38,000 lbs half loaded, and I wanted an anchor and rode such that when set, I could sleep soundly, as I am sometimes hard to wake.
There are a wide range of prices out there for the same equipment. Search the deeper pages. I found our Maxwell at hodgesmarine.com but there are others with much lower prices than WMarine or Defender
Also look at the online Maxwell installation instructions for the size of electric cable needed. PO had used much undersized wire.
Good luck.
