I've done a fair amount of towing with my 2000 Windstar LX 3.8. It doesn't have the factory tow package.
The stock Windstar 3.8 is rated to tow 2000 pounds (the factory Class II tow package increases this to 3500) . I've towed a small utility trailer for several thousand miles without problem (the trailer weighs about 1000 pounds, fully loaded). I don't believe you'd have any problems towing a 700 pound jet ski (I'm presuming the trailer and related items would only add a few hundred pounds).
The only things I did to my Windstar for this towing were:
- Add a class II hitch with 2" receiver
- Upgrade to a full-size spare (the normal carrier handles a full-size wheel and tire without problem).
- Add the wiring needed to handle the trailer lights.
A word about Windstars and trailer lighting: The lights on newer Windstars ('99+, IIRC) use ground-side switching. This means the simple method of extending the tow vehicle lights to the trailer won't work. You'll need kit that includes (essentially) a set of isolation relays that control the trailer lights. I purchased a kit (about $50; I got mine on eBay) that was specific to the Windstar, which simplified installation.
I've recently been upgrading my Windstar to tow a small popup camper (2500 pounds GVWR). My upgrades included:
- A transmission cooler (the largest thin-profile cooler I could fit in front of the radiator and condenser; a B&M cooler purchased through Summit Racing).
- A set of AirLift 1000 spring airbags. Note that they DO NOT increase the load carrying capacity of the van, but do help firm up the rear end of the Windstar, which is very soft.
- A number of wiring upgrades to drive the trailer brakes (smaller trailers generally don't have their own brakes) and to supply auxilliary power to the camper (I want to be able to run the 12V fridge while driving).
Note that the tow capacities listed in your owner's manual generally assume limited passengers and cargo in the tow vehicle. Read carefully and do some research.
