I don’t know any of that l just got the boat. No prop on it so no idea? Guy l got it from said it was in the boat but it’s not. He’s looking around his garage to see IF he can find it. That’s why I’m hoping somebody with an 88 sun runner can tell me what they have.Will almost certainly be a RH...but I’m afraid everyone is guessing at it...unless you provide more details
what rpm was it seeing wot ?
What’s the gear ratio ?
What gps top speed did you see ?
Start with a 19” pitch 3 blade aluminum black max type . see where your wot rpms land adjust pitch up or down from there.Ok have to check and see I’ll get back thanks
