    Default Prop Advice Needed

    Purchased a 1994 Crownline 196br with a 305 and Alpha One outdrive. The propeller on the boat is a 19 pitch 14" diameter and has three blades. With this prop its a turd when trying to plane out with people in the boat and pulling tubers, takes forever to get on a plane. Was thinking of changing it to a four blade with a 21 degree pitch to help to plane out better. I know I will loose overall speed but want to get out of the water better. Also need the prop repaired and wanted to know who and where to have this done. Thanks Scot

    Putting bigger pitch will make it more of a TURD. If your going to pull tubers you'll need lower pitch prop. That will help you get out of the hole better.

    If it's banged up, that's why it won't plane out.

    Get yours fixed and try it first. If the doesn't work try a 14-3/4-x19p Stainless Steel prop, that should do what you want it to.

    that 305 might have a hard time with anymore pitch.

    Ok so I got that pitch thing backwards. So go with a 4 blade prop and decrease the pitch to 18 degrees would be the way to try?
    The old prop has always had a hard time planning out the boat, I know it needs repair, but wanted advice on a different prop so I can use the old prop as a spare. Will keep the stainless steel one in mind but due to its cost would rather go with a aluminum prop. Thanks

    That boat should plane just fine with a 19, time to look at plugs/wires/cap rotor. I see this all too frequently.

    I wouldn't go for a 4 blade, there really isn't anything there, do as he says ^ a good tune up, if its still a problem go with a 14-3/4 x19 pitch. as I understand the diameter of the prop 14-3/4 is what gets you out of the water the pitch determines your speed.

    While at top speed do you know what RPM you are running?
