    I feel its time to replace my prop due to corrosion. I currently have an 18x20 4 blade on there. I cannot ID it further than that. I did some searching. I could not really tell whats preferred on these. I figured while replacing, I might as well confirm this to be the best choice to go back on. I seem to get plenty of speed from it compared to what I read.

    I would contact ACME propellers and see what they have to say.

    You need to replace your prop due to corrosion? You really need to chase that down. Are you replacing your shaft zincs very often? Are you slipped or trailering her? If in a slip, stray current may be a reason for severe corrosion. And you need to check your through hulls too.

    My shaft did not have a zinc. I believe the Boat was kept in a slip by the PO. I have it on a lift.

    A lift is WAY more protected than in the water all the time...BUT...an issue is an issue... check it out and correct it.
