Have a question, am new to boating(well, away for 20yrs) bought a 1993 Rinker Fiesta Vee 260 this Sept, when I pulled it uot this past week noticed the prop was pretty banged up, needs to be rebuilt, want to get a spare but #s are unreadable, anyone know what the prop dia & pitch is recommended for a 30ft Rinker with a 5.7 mercruiser?
