Hello Trent I have used the 6x6 for about 4 years now with know problems to speak of it works great The ones I use are built by a company that is not to far from where I live.They are the best on the market a little bit more expensive but well worth it. THey are called Hydro-traxx. They are hydrostatic drive and they have a true zero turning radius they are rated to be able to haul 1000 lbs in the water and will run at 5 mph they run from 18 to 25 mph on land they are very reliable and don't leak a drop they are made out of molded fiberglass and come with 30hp motors or 44hp disels there great for pulling trees out of spillways or installing foutains or aerators.I would spend all night explaining my mixtures they are set to guide lines by the state. The only draw back that I have found is in doing lakes that are largeer than 25 acres and don't have bank access .Gota go for now doc'
