Prop help

[Stephen Roberge]

im running a VS1 with a stock water cooled O.S. 3.5. I ran it for the first time today, the motor is tight most likely not broken in yet. I have a balanced and sharpened M440 2 blade on it right now but it seems to be running a little wet. Before I start really messing with trim, is this the right prop to start with or should I try so els?

 

[Carl Van Houten]

I have never run a VS1 but we run ABS 4053-2 (S&B only) or the Octura 442 Lynx cut props on our stock tunnels.

thank you

I ran a VS 1 for years and the M440 is a decent prop for this boat. You should be able to use the M440 to begin making trim adjustments. I ran the center line of the props 1/4" above the bottom edge of the sponsons and neutral thrust angle. I also had 2 oz. of lead on each of the sponson tips.

Thanks Jerry I have some more changes to make. The last two days the weather here has been crap! Very windy so hopefully next weekend it’ll be better to run.

What other props would you use?

 

[Carl Van Houten]

I haven't used a 440 on a 3.5cc outboard since 1980. That is not much prop if you plan to race that boat but like I said I have never had one of those boats either.

 

[Stephen Roberge]

What prop do you suggest Carl?

 

[Brandon Atwell]

M440 should be a great prop for setting your hull up. I normally recommend that as it is incredibly easy on the needle and trim adjustments.
I run a 40x53 for heat racing. I haven’t raced a VS1, but I have ran one for fun. I think the 40x53 will be a good option if you plan to race. Otherwise, run the 440 and have some fun!

 

[Carl Van Houten]

I agree that it will be a forgiving prop but you won't catch Brandon's boat using a 440. He would love it if everybody had to race him using 440 props.

Anderson 1440... is my choice.

[Carl Van Houten]

The Anderson 1440 is more like it. That prop will keep you on the same lap with the fast guys and that is a GR boat so he should know what it likes.

 

[rumrunner]

abc 40 x53 is the go to prop . works great on anything.

 

[Brian Sorgente]

Some good info here.

Out of curiosity, what kind of speeds are you guys logging out of the 40x53 on the stock OS and for the heck of it, your mod boats as well?

I would say low to mid 50’s is a fair estimate on a heat racing setup. My 40x53 on my stock boat has kept me very competitive with a lot of Mod 3.5 Tunnels. The x442 also is a great option but requires some more tweaking. The 40x53 has given me and Mike Talley some great racing.

On a mod tunnel, we still run the x442 with a lynx cut currently. We have clocked our hull on the lower end at 59 MPH with a heat racing setup. I would say our time trial setup most likely saw top speeds of 62-63 MPH. Never ran a SAW pass with it so I can’t say for certain.

Mike Z’s stock hull with the 1440 absolutely flew at the Internats. I left before Sport 3.5 racing due to work and did not get to race, but between him and Mark Anderson and Eric Bourlet, those boats ran exceptionally well.

If you still have the head shim in the motor. Pull it out. That will make a big difference in the way it runs. 40x53 as stated is a good prop. 1440 back cut and cupped to 2.7 is the best 20 tunnel prop that I have ever used. Gary Pruesse and I started working those 20+ years ago. Still the only prop Eric and I run. I have tried so called lynx cut props and never had them work.

Steve a prop4u lynx cut m440 is what i ran. Many props will work it just seems that prop worked best on my vs1

Can you pm me what props you have and pricing as I will need a few. Thanks

Stephen, Contact Brian Buass. He is a member here, Goes by Raptor347. I no longer do props. Did them for years, and now very rarely do any. Brian is one of the best.
