I ordered the NFB 4.2 with 19'cables for my Revenge V22 with a Johnson 175hp on back. My concern is numerous people have told my I should have twin cables for this size engine.(I removed 2 Safety QC helms bolted together with 2 cables going to the rear of the boat. Only one was connected.) Maybe the previous owner had twins at sometime. I don't know.
Anyway, West Marine says this single cable system is all that is necesary. Any comments? Do I need to purchase a second helm and bolt them together also? Hydraulic steering would be preferred but budget doesn't allow it this year.

Thanks,
David

The Teleflex rigging manual does not give a maximum HP rating for the single cable steering. It does state that is for V-4 and smaller outboards. Think you would be much safer with the dual cable system.

When I bought the NFB system, the 1 vs 2 cables was also my concern since my old cable was dual. The no. of cables is based on the boats estimated top speed. The single cable is used for up to 50 mph.

Never scared

whaler22 has already consulted with me about this and I recommended a twin cable set up. But I should really explain why I feel this way. There are basically two reasons:

1) My 18 Outrage had twin steering cables as did all the Classic Whalers over 17' (at least in the 1980's) If this is how Whaler did it then that is how I would want it. Is it absolutely necessary? Probably not. Lots of other 22' boats have a single cable, but the 50 mph guideline is just that. It is not some magical boundary where everything changes once you cross it.

2) Twin cables will work better. This is really the real reason why I would want twin cables. Any mechanical steering cable will have a bit of slop in it. By using twins cables you can (and should) adjust them so the slop form one cancels the slop from the other. By this I mean that one cable essentially pushes while the other pulls.

I always liked the twin cable steering on my Outrage. It was a huge improvement compared to the single cable on my Montauk. Others here on the FORUM have disagreed about the worthiness of twin cable steering but I really liked it.

Dual cables sounds like a pain in the butt. I would run the single cable for now and upgrade to hydraulic steering soon. There's some hydraulic steering parts on ebay right now. If you shop around some boat junk yards you could probably find a whole hydraulic setup for much cheaper than new. The only parts that differ between motors are the actual attachment pieces from the cylinder to the motor. The cyclinder hoses and helm are all the same no matter the application.

For a Revenge 22, I would only go with Hydraulic. I don't think the NFB 4.2 will be easy to steer. Although the NFB will lessen load with prop torque.

The dual cables are recommended for V-6 engines. The redundancy is for safety. Increased efficiency/effectiveness of dual cable steering is debateable.

Also, the lock to lock ratio of 4:1 on NFB is the same as Hydraulic.

Some may find this interesting. West Marine suggest only one cable because of the speed is under the 50mph as mentioned above. I agree with Tom that twin cables have there advantages...i.e. being able to remove the slop in the cables. This is what they do on high performance boats to stop any movement of the motor while at speed.
I still couldn't find out how to rig dual cables with the 4.2 NFB helm. West Marine only stocked single cable helms. I contacted Teleflex. They do have a dual cable helm 4.2 system but the cable length only goes to 16'. I'll be contacted soon on what a special order kit will cost with the 4.2 NFB Dual Cable set up with 19' cables.
Thanks for the input guys.

All Whalers 18 Outrage size and over, came with dual cable steering. It's a nightmare if you ask me, hard to adjust, binds up, etc. I don't think they are even using it anymore. I had it on my 18, and got rid of it and couldn't believe the IMPROVEMENT in switching to hydraulic.

Cancel the order, and get hydraulic. You'll wonder why you waited so long. The increased happiness in piloting your boat is well worth the money!
