I have a Marine Power 100mm nozzle, It fits on a Kodiak posi nozzle base and it did clear a stock Hamilton 772/773 reverse bucket. I was using it to try out several combinations of nozzles and impellers. Less than 30 minutes of run time so it's basically new. The stock Kodiak posi nozzle is either 92 or 94 mm so this is a nice addition to try out different sizes without boring your stock nozzle. $100 shipped to the lower 48 (I'm located in NJ).
