I would change the filter. I didn't think it was possible for a filter to be so gunked up that the hydro wouldn't work, until a new to me 1811 would jump about 1o feet, stop, repeat--etc. Installed a used filter of a junk rear and problem went away. Of course I had a trans. full of water too. Changed oil and filter and hydro works great. I would spend $15 on a filter if it were mine.
