Throttling a twin outboard rig

Morning,

I have never driven a rib with twin outboard and out current boat is less of a problem...

Say for example you have a twin outboard set up (say for twin verados) how easy it it to throttle when pushing on in bigger seas? do you need to place your throttle hand on both throttles and move them in sync or is there the ability to sync throttles and just throttle using one lever controlling both engines?

Guess its not so much of a problem for me with my giant hands but when the Mrs is helming with more delicate paws it would be quite difficult for her.

also, when helming "with enthuasium" on single engined ribs i find it more controlable using the side of the lever rather than the handle part (if that makes sense) guess this would be difficult on twin setup??

thanks in advance...

Hi have used a Tornado rib circa 6.5m with twin 100 hp loaded with divers. I did not find it hard to manage the two trottles. On that particular boat the balance was brutal ( Very Tail heavy) but the bottle rack was on the transom. The boat was very slow to react to trottle inputs in big seas. It was a pig of a boat ruined by very poor balance.

Based on Steves Verados on his parker ...the fly by wire tales some getting used to as its nice and light, and if not used to it can take you by surprise , but really think they are great once used to them.

Need to push both at the same time - but they are set up for this so its easy to do with one ( even small hand) . They sync the revs if they are within ( I think ) 10% of each other , but they wont move themselves...

I know you can rest your hand on the throttle mount to make it easier , but I personally dont like this way...I just got used to holding the throttle levers as normal ( and felt after a day or so I was suing muscles I didn't usually - but this went after a couple of days as my arm was used to it)

Twin throttles usually tend to have the top of the throttle levers curved into each other so they are easy to hold both with one hand.

Digital throttles on larger boats can be set so you can only use one lever. The second lever is only used when maneuvering. I am guessing modern outboards would be the same but I am sure someone with more knowledge and experience will be along to confirm or deny.

You are correct as the latest DTS throttle levers for the Mercury Verado engines have a transfer button to disconnect the starboard lever. The transfer is done when in Neutral and the starboard lever is put in the full reverse position and you only use the Port one to operate both engines. Simple

This is what we installed on Solent Voyager the red Parker 1000 Baltic which operates from Cowes.

One of my personal bugbears with some twin setups /controls is when there is no 'link' for trimming both engines simultaneously.....

Obv they should be unlinkable (new word? ) for individual op, but its a total PITA if you have two single controls side by side with trim for each indepenently on each stick.....

Thanks all,

Seems its a question of practice makes perfect or if its a fancy new set up they may have the ability to link....

agree with the need to trim independently but also together at the same time! with the fancy controls now days it should be possible!

The "ordinary" non digital bog standard BRP (Evinrude) dual controls allow synched & independant trim/tilt.

Its easy enough to wire the PTT so you can do either engine or both.

The yamaha controls on mine have a three buttons for tilt - one is on the port lever where your thumb goes to trim both engines at the same time. And then down on the mount part, theres two individual ones to trim the engines independently.

I used to find myself pushing one throttle more than the other when I first started with it - but after a while you get used to it and if they come out of sync you can feel it in your hand easily and sort it out.

I just love the feeling of being at stand still or pootling along at 6knots and then throwing both throttles forward - the boat leaps out of the water and goes like stink! The sound is pretty good too

My boat will be on the water again soon if you wanted to have a play at some point?
