I just installed a maxwell 800 windlass on my 248. The unit I bought I got for $800 complete which included the solenoid pack. I had a fiberglass shop mount the windlass as I didn't feel comfortable filling the hause pipe hole and cutting a new hole in the deck. They ended up having to make a fiberglass pad to get it to sit right on the deck. That was $1000. The windlass looks like it came right from the factory now. Don't forget you will need a new anchor rode approx $300. I did all of the wiring my self. If you choose the right windlass you can use the factory wiring..... either the maxwell 500 or the lewmar v700. In my mind this is well worth it as I have 2 very young children that need to be watch so the cost is worth every penny!
