Bow lift vs. Stern lift ?

[roll tide]

What are some props for boats that need bow lift, and what props create stern lift ?

In my experience a 3 blade tempest plus gives alot of bow lift and a 4 blade trophy plus gives more stern lift.

trophy gives decent bow lift and stern lift. TXP OT4 gives awesome lift on both ends. Four blades have more stern lift than bow lift as a rule when compared to three blades but many of them have good bow lift as well. Four blades also carry a load better and are easier to drive. Go to www.mercurymarine.com and read about their props.

Thanks for the input. I just put a jp on my boat 'and it still needs more lift, its a heavy boat that is not designed to create lift like alot of boats. I just was wondering what prop would be a good choice to try. I know its mostly trial an error but I knew some of yall have ran many different props and knew which ones did what on your boats .

what kind of boat and motor? Im messing around with mine right now and just raising my motor an inch higher made a noticable difference. I got a few more rpm's, more lift, and even a couple mph more up top.

Its a 88 bass tracker 1800 with 87 150 xr2 its fiberglass. Its has 6" plate set 4" below pad it ran 55 gps at 6100 rpms with 23 ballistic with less than half the boat out of the water. any advise ?

I would definately raise the motor up. 4 inches below the pad seems way too low. Thats a strong motor and it should push that boat alot better. How much water pressure are you currrently running at Wide Open Throttle with the current set up?

Do you have a water pressure gauge? Need to figure out water pressure first so you don't raise it to much and possibly toast your motor. Once you know that your water pressure is good then you start raising and fine tuning it. I've been with James (Wrechin2) setting-up boats several times and 1/4 of a inch up or down can make a huge difference in lift, speed, and water pressure! So getting out there and making a pass writing that down then raise it, make another pass and so on you will figure out the "sweet spot" for your boat.

You should meet James and I at the lake one weekend for one of our test/play days! I'm sure James has a prop or 2 that he wouldn't mind letting you test out! You can also help me make fun of James when his helmet blows out the boat again!! emoPoke emoTongue

Hope to see you out there even though you yell for the wrong team!!! emoToast

Gauge isnt workin, first trip this year it stuck so cant raise it yet . I heard a tempest plus has good lift.

I would get that guage fixed before I did anything else. Water pressure, especially a lack there of, will cook a motor in a hearbeat.

Sounds great. Talked to James today and he is goin to let me know when the next play day is . Id like to see your boat run in person and and as for your team the only prob I have with them is they have orange as a color. emoPoke Hope I can make the next one.

That is why I left the engine so deep when I installed the jack plate. With the gauge not working and none of the water intake holes filled in, I was not going to be responsible for a cooked engine. </p>

Get the gauge fixed and I will meet up with you at the lake one day and we will try several good running props on heavy bowed boats. emoToast </p>

The 26 chopper hated your boat and would blow out easily. Here it is on Wes' bullet.</p>
