Hello all, Great site with some great info. I was wondering how everyone bids powerwashing boats? I live close to the water and think this would be a great quick hit. Is an accurate estimate .15 a ft? Please let me know. Also, is a John Deere 3000 psi, 4 gpm sufficient for strictly residental? Can most houses even supply 4 gpm or should I bring a 55 gallon drum? Any help would be appreciated. OOH RAH!!!
