So..... you could buy the trailer dolly and custom fab it to tow/park the boat. Brilliant!!ok, I'll bite. This is going to have to be custom built. and in all honesty, it may not be worth the effort. 1. you're potentially overloading the front of the bike. causing spring fatigue, alignment issues, and if it's to overloaded you risk bending A-arms or tie rods. 2. it's not that hard to use the quad towing from the rear. and most ski boats will exceed the towing rating for the ATV. and 3. a trailer dolly is $49 at Harbor freight. and it's easy to use. granted it's not motorized, but I can move my 1600 lb tandem axle around with it. so take that for what it's worth.
Exactly what im going to do!We did exactly that do my dads bike for the exact same reason. We bought just a bolt on hitch and fabbed it on the frontend. And he only uses it for pushing power. Keeping jack with wheel on the ground to support the weight. And his is only 2wd so plenty of room to install hitch. We also use the bike to push a racecar around the pits with a push bar that also slides into the hitch.
