Attached is a PDF from a prop shop that has the recommended Acme props for the Toyota Epic. The recommended 3-Blade Acme prop is the 541 and the recommended 4-Blade Acme prop is the 209 for all Epic models (bottom of the form : chart for Acme props only).
Google search '3 blade prop verses 4 blade prop' and you will find multiple "opinions" on which type of prop is better. Better hole shot, better top end, more vibration, less vibration, better fuel economy, salt water, fresh water, turning radius, wake character, etc., etc.
Search the forums on this site as well. There are several threads regarding prop selection (more opinion but at least it's from Epic owners who have used the props on their boats). Hard to know if you made the right choice until you install the new prop &
Get Wet.
Unfortunately, I have no recommendation. Still got the factory prop on my '01 SX. When I do replace my prop, I'm going with the Acme 541 (based on my research of other peoples "opinion"). Good price at Nettle Props - $354.89
