    prop?

    I have a 4-3/4 lower unit (78 150 v6), but I have a 4-1/4 prop, from a xr4 / I6. It fits, but is there any down side to running the smaller prop hub, like Performance? Thanks, Jared

    prop pitch?

    I have a 16.5' checkmate with a merc. 150 and a alum. 23p prop. My boat runs 56mph/gps @ only 5000rpms. My question, will a ss mirage 21p prop get the rpms up where they should be, or do I need to go even lower in pitch than a 21?:confused: And will this kill my top end?:mad: Thanks Jared.
