newbie prop advice??.. 350sbc dd

[ottonocturnal]

I am looking for a few opinions on what style of prop to use. 350 sbc dd 12ft glass hull. i have a 66" 5 blade warp drive on the boat now. it had tip damage and was cut down to 66" by previous owner. i have had the crank shaft inspected and its still strait, so im down to getting a new prop. i do not know exactly what boat weighs but no poly and minimal gear, and the fact that iv spun the boat around myself on a bank already..ha, leads me to believe weight isnt my big issue here!? boat does not run dry...is that typical of sbc? would a new style and of course undamaged prop give me more push?.. thanks for your advice

my buddy runs a 12ft apache with poly as a hunt boat 350dd...he was running a 72x38 wood prop & boat wouldn't run dry fer crap..just bought a used 72in water Walker signature series & boy what a difference..night & day..not saying it won't get stuck but what boat wont lol,but he comes to camp loaded down now & runs up on the hill with no problems & leaves without being hung up!!

Well the 72lxl38 if it was a paddle prop is more of a caddy prop.

Sensenich - Q, NGH, Alpha
Water Walker - Cypress or Signature
Whirlwind - Whisper tip, Razor, Excalibur

and if you have wrap drive plates you have the saber or razor option
Just take a minute a call each one and ask what they recommend. All priced about the same.

no the 72x38 wasn't a paddle was a stick prop

Try and test before you buy. There are a lot of differences between DD 350's, but you are likely generating roughly 180-200hp at 2800. If that is the case, try and see if someone with a strong AC 4 cylinder (like av lycoming) will let you try their prop. With some mods you could be generating more hp but that is typical if you slap a prop on a crate motor.

Most DD 350 run good in deep water, great in shallow water and get hung up repeatedly on land. I have seen exceptions, but that is the rule. Before you spend money on a prop that might not be a solution, it would be best to see.


Good luck.

I run a 70" q series on a 12 foot sled with dd vortec 350 and I can go pretty much wherever I want, usually with a passenger and cooler.

Try to find some four blade plates and run 4 blades. I run a four blade 68 on my 350 dd and it goes pretty good.

That green grass is tough to run, but it looks like you have a light set up.

What Pat said, 70" Q is hard to beat on a DD 350.
