Lastdraft Posted July 10, 2020 Share Posted July 10, 2020 Researching my Morse control system online I keep seeing the phrase ' lost motion' . Does anyone know what this means in the context of control systems ? Thanks Quote Link to comment Share on other sites More sharing options...

ChrisB Posted July 10, 2020 Share Posted July 10, 2020 Sounds like it is not engaging. Staying in neutral. Quote Link to comment Share on other sites More sharing options...
Vaughan Posted July 10, 2020 Share Posted July 10, 2020 Perhaps if you told us why you are researching your system we might be able to suggest what is wrong with it. 2 Quote Link to comment Share on other sites More sharing options...
Lastdraft Posted July 10, 2020 Author Share Posted July 10, 2020 the Volvo system use ds units for gear, but a 'lost motion' link with two throttle cables on each engine.......... ' lost motion' I think is possibly something to do with activity or lack of it between control lever and gearbox ? Quote Link to comment Share on other sites More sharing options...
OldBerkshireBoy Posted July 10, 2020 Share Posted July 10, 2020 Like a false neutral? Quote Link to comment Share on other sites More sharing options...
grendel Posted July 10, 2020 Share Posted July 10, 2020 maybe a push pull system. Quote Link to comment Share on other sites More sharing options...
Vaughan Posted July 10, 2020 Share Posted July 10, 2020 You are still not telling us what you think might be wrong with it, on your boat. Quote Link to comment Share on other sites More sharing options...
grendel Posted July 10, 2020 Share Posted July 10, 2020 looking on this page the lost motion seems to be for dual position helms, and the units require to be in neutral before engaging the second unit, the parts are shown here https://www.asap-supplies.com/steering-and-controls/dual-station-control-units 1 Quote Link to comment Share on other sites More sharing options...

Smoggy Posted July 10, 2020 Share Posted July 10, 2020 "lost motion" is something you find a day later in the back of your socks after it fails to engage reverse in a close manouvering situation in a strong breeze. Quote Link to comment Share on other sites More sharing options...
OldSuffolkcodger Posted July 14, 2020 Share Posted July 14, 2020 Lost Motion, this term can best be explained by the motion of the control lever, is"Lost" by the time it reaches the other end. Usually caused by lots of little bits of slack in joints etc. Quote Link to comment Share on other sites More sharing options...
annv Posted July 16, 2020 Share Posted July 16, 2020 Hi You may find it refers to the slotted control on duel control there are two slotted bars when one is pulled the motion is lost in the parallel one as the pine slides up the slot and is lost it is then returned by a spring you can then pull the other one with out affecting the parole one .
