If you had to do it over again boat build

Postby spooledup50 » Wed Aug 13, 2014 2:29 pm

Started pulling the 4.3 off my boat to install sbc 350ci brodix heads mild cam should produce 400hp almost double what i had with the v6 .. 2.37 box ratio

This is on a 11 foot boat with high sides

On the v6 I had a 6 blade warp 70 inches boat was like a bull dozer point and go at 12 degrees of pitch and break loose at 3000rpm on dry ground

I'm thinking that I will need to ditch the old warp and go with modern times


Any one with a similar combination
I ride mostly family style out around the lake wife and kids hunting is getting hard to do anymore just can't find the time

Looking for good all around. Top end speed not that important. I don't really want to buy a three blade prop .

Thanks for your time and I appreciate your comments

I really like my 2 blade whisper tip SW. It pushes real good with the boat in my signature. you should be able to spin it about 5grand on the two mark with your set up and cruise @ 3k rpm's or lower. Get with Terry on here his screen name is PTR34 I think. I bought mine from whirlwind but could have gotten a SW sensenich from him cheaper (after the fact).

Why don't you want a three blade prop? If I were you I'd put a three blade R on it. You'll find that it will out perform that warp by tons. Not nearly as hard on the ears either.

What is max diameter prop you can run? I would stay with a narrow blade prop. Less torque roll on that short boat. Depending on length you can run a 5 or 6 blade Saber/Razor would run good.

I have been considering the razor blades due to the fact that I already have a six Blade hub
I was told the razors are more of a high-speed prop

I'm looking for more All around performance you think the razor are in that categories

And 78" max

Those three blades are great all around props. While the SW blades rob power due to their large surface area they perform very well and are great cruising/bulldozing props. If your going to stick with that motor/box combo I think you would benefit from not going to the 3blade due to the higher cost and you would end up being over propped. A 2 blade SW should work for that combo just fine and put you at the max blade RPM at your torque curve. BUT Definitely reach out to the prop manufactures - they are experts when it come to their products :thumbleft:

Scott

Thanks I two feel like a three blade is over kill
I weighed the 4.3 with no carb and it was 380 lbs
The 350 was only 421 about 50 lb differance when all dressed up and almost double the power
The warp was set at 12 degrees I have herd people getting 17 degrees so I'm sure it will work behind my new motor for a while I'm just really tired of buzzing ears

I got 3 h blades i'll sell ya. had them on my 406 till the r blades came out. 3 r blades are what you want but you might be short on torque. Mine are set on 2 mark and she spins max at 5200 with 2:37 box

That size boat would eat all day with a 3 blade on it. I run a bigger boat with a little more power it's the ticket for me. If your around Ocala you can try mine. About to send them to be spruced up with that duraskin
