| Post subject: | NFB Steering Good/Bad |
Been getting some seat time with the Dual NFB on the 16 Murph and XR4 150. Hit it on this weekend in the ruff at West Lake and I'm just loving it. Been waiting for this no steer I hear about and it just's not bothering me. Thanks for the warnings, we did proceeded with caution. It is different and taking a bit to get the brain to sync up with turning it on and off when required. Slight adjustments to the prop torque seems to give me steering control and a feel of the hull. I find a combination of using the foot throttle and a wiggle wake up on the steering wheel works as an on/off switch. Another element I found with the on/of control is how much the prop blade is in contact with the water. On launch and when playing with the trim running the Chopper, anytime you have roosting or have cav going on you have control. When blasting the rough at speed I was amazed of the boat feel I had while managing the boat rollers coming at you with the boat was scabin' too. With the prop catching lots of air the NFB seemed to sense this and allowed me feel and control. At times I have a racketing effect of the clutch which is quite loud but didn't seem to affect control. Not sure if this is right, wondering if i will break it? Anyone every had one break under way? |

Don't know, no speedo, just tach. Haven't had the right water conditions yet to wind out right out. Not sure if I will as that might be 6400+. Not my motor. LOL With 10gals fuel and 550lbs in cargo, 6000 is easy. That's with the 1.87 gears and 28 Chopper. 6200 been pretty easy by myself for some short bursts before running out of lake. It's got tired mounts and could use some more setup. Got a little more time to play around and then we will have the rebuilt 115 back on her. |

Damn, I wish this had of come up on the weekend, I would have asked you to drive mine!!! Steering locks solid when you get up in speeds. Now sayin that...... When I installed my drag plate I noticed a grease nipple that I hadn't seen before, on the steering tube itself. So I greased the steering tube, trim pivot, and cable tube. Handling was slightly better at west lake, but still locking. |

Murph - I am not familiar with a NFB system. When you say turn it on and off without flicking the throttle and pulling on the wheel would it stay engaged but allow you to steer? |

I'm thinking he's experiencing some lockup, but able to "free" it up with throttle or sharp steering input?? |

You got it. We take full advantage of the the clutch lockup when torque is needed. This tired body can't hold that anymore. Was able to spray the dash board from the back of the boat. LOL. Just lock it and accelerate. |

The thing about that is it seems to get gradually worse. The faster I go, the harder it is to get it to free up. I want to be able to run higher speeds with my boat without worry of not being able to get out of trouble if I get into it. I can deal with it the way it is now, I've learned how to drive it the way it is, but I see Pat with his setup and Shane with the same setup as mine, and they're having no problem whatsoever, makes me think the lockup IS a problem. |
