A 9X9 ----3 blade -----13 tooth spline----For NON through hub exhaust.----0763585----First # is for 9" diameter second # is for 9" pitch.----And on a 20' boat you might need a 7 or 8" pitch.
Sorry, but I can’t seem to find anything that matches this. Everything I come across at this size isn’t for a 13tooth spline. I’m in the UK as well so not sure if that’s making things difficult?!
