I am repowering my Humber 6m Ocean pro RIB. I want to replace the throttle cables and steering at the same time but I hate having this loop as it is a trip hazard and I will mainly be boating solo. My new engine is a 2005 Yamaha 115hp. This is brand new, never been unboxed. Its been sitting in the crate in somebodies garage for 19 Years, hahahaha.

It is my belief that it probably doesnt have an NMEA option as that came in in 2006. However i have seen it suggested that it might be doable retrospectively on a 2005 motor.

Can anybody clarify rhe situation on that for me?

If not viable, can I install the throttles without having a loop and if so...how do I measure for these shorter cables?

Many thanks in advance

you have a loop there now because your cables are too long for your boat.

google measuring marine control cables.

Is it even NOT rotted out ? Unsafe for that HP motor ? Fabrics are not meant to be folded that long and not develop stress folds. Be sure you have a great life jacket & E PERB unit on the first. ....Walk to shore if necessary. Good luck.

The throttle and control cables need to be long enough to allow the engine to steer, without kinking or pulling the cables. The same is true when the engine is tilted up.

The cable length formula on the cable manufacturer's web site is the best way to get the right length.

Thanks for your response Scott. I have previously googled it but most of the advice is to add 4 feet to create a loop to minimize risk of "kinking" when fitting throttle cables to an outboard motor. A small percentage of sites do not suggest this but at least 80-90 percent do. That's very high, so it's making me doubt not doing so would be viable. I am really hoping to find a definitive answer on this if I can.

I am a little confused by your response. Is what "rotted out"???
The boat is rated for up to a 150hp or 200kg. I assume this could have only been achieved with a 2 stroke 150. The 4 stroke motor weighs 171kg
