under sail with engine stopped

1. Introduction
Yanmar wishes to inform you about the instruction of the control lever position during sailing under
sail with engine operation stopped. This instruction is subjected to mechanical type gearboxes and
sail drives only.

2. Operation instruction
2-1 Mechanical Cone clutch :
Applicable models: Sail Drive: Models SD 40, SD50 and SD50-4T
Marine gear: Models KM2P, KM35P, KM35A and KM4A
When mechanical cone clutch type gearbox or sail drive is equipped with the following propeller:

a. Fixed propeller:
When sailing under sail with engine operation stopped put control lever into Neutral. The output shaft keeps rotating.
Notice:
When control lever is put in Reverse position, cone slippage will be introduced and void your warranty and there is possibility that the clutch doesn't disengage. This can be a problem for
engine re-starting.
There are options to stop free rotation of propeller-shaft if customer doesn’t want occur noise from rotating propeller:
1) For sail drive: install folding propeller or Feathering propeller instead of fixed propeller.
2) For marine gear: install the Shaft - Lock device, Yanmar does not supply, on the propeller shaft.

b. Folding propeller: (including GORI Over-drive propeller)
When sailing under sail with engine operation stopped put control lever into Reverse position, this to operate the folding propeller to fold close blade and output-shaft stops from rotating.
After this operation put the control lever back into Neutral.

c. Feathering propeller:
When sailing under sail with engine operation stopped put control lever into Reverse position, this to operate the feathering propeller into feathering position and output-shaft stops from rotating. After this operation put the control lever back into Neutral.

2-2 Other Mechanical clutch:
Applicable model: Sail Drive: Model SD20, SD31 (Dog clutch type)
Marine gear: Model KBW10, KBW20, KBW21
(Mechanical single or multi disc clutch) When mechanical dog clutch or mechanical disc clutch is equipped with the following propeller:

a. Fixed propeller:
When sailing under sail with motor stopped put control lever into Neutral. The output shaft keeps rotating.
Notice:
When control lever is put in Reverse position there is a possibility the clutch does not disengage.
This can be a problem for engine re-starting.
There are Options to stop free rotation on propeller shaft if customer doesn’t want occur noise by rotating:
1) For sail drive: install folding propeller or Feathering propeller instead of fixed propeller.
2) For marine gear: install the Shaft-Lock device, Yanmar does not supply, on the propeller shaft

b. Folding propeller:
When sailing under sail with engine stopped put control lever into reverse position, this enables the folding propeller to fold close blade and output-shaft stops from rotating. After this operation put the control lever back into neutral or remain reverse position as you like.

c. Feathering propeller:
When sailing under sail with engine stopped put control lever into reverse position, this enables the feathering propeller into feathering position and output-shaft stops from rotating. After this operation put the control lever back into neutral or remain reverse position as you like.

Notice:
Do above mentioned operations with a boat speed <3knts when sailing under sail with engine operation stopped.

È consigliato spegnere a marcia inserita perché l'elica potrebbe continuare a girare mettendo a folle, per una serie di concause che credo siano ovvie e dovute sia alla velocità del fluido e sia alla forma delle pale.
Inoltre, inserire la retro mentre l'invertitore ed asse stanno girando potrebbe causare danni

Ieri incuriosito ho fatto delle prove e sono rimasto incredulo: credevo che con marcia inserita l'invertitore restasse bloccato ed invece no. Con ewol se spengo il motore con marcia inserita si ferma subito a bandiera ma se provo a girare l'elica, essa è libera di muoversi. Se invece, con motore spento, inserisco la retro, l'asse si blocca in un verso e nell'altro continua a girare

sono incuriosito da quanto affermato da TestaCuore.

Come è possibile ciò. Qual'è il modo corretto?

Una mia idea, prima di riavviare bisogna mettere in folle prima, io faccio sempre così.

Preciso che la prova l'ho fatta stando fermo all'ancora

Buonasera a tutti una domanda con autoprop Montata su un volvo d2 75 mi hanno consigliato sia di spegnere lil motore con marcia inserita in avanti e lasciarl durante la navigazione a vela che di riaccenderlo in caso di navigazione a vela sempre con marcia inserita in avanti. Cosa ne pensate ❓

ciao
ne penso che devi chiedere a Volvo Penta, quello che o ho sopra-riportato vale per Yanmar che ha emanato il Technical Bulletin che ho riportato.
per Volvo non lo so e non voglio correre il rischio di darti un consiglio sbagliato

Io sono costretto a mettere in moto con marcia inserita in quanto dopo veleggiata con marcia avanti inserita il folle non entra.(YANMAR 3YM30 AUTOPROP 3 pale)

e ti va già bene che non spacchi i coni frizione!!
come vedi dal technical bullettin riportato da me sopra, YANMAR chiede venga lasciato in folle:

c. Feathering propeller:
When sailing under sail with engine operation stopped put control lever into Reverse position, this to operate the feathering propeller into feathering position and output-shaft stops from rotating. After this operation put the control lever back into Neutral.

Stefano Cova Che vende le Autoprop ha sempre detto che a vela va inserita la marcia avanti.

Anch'io stesso motore, stessa Elica, stesso problema

Stefano Cova è stato messo al corrente della direttiva Yanmar ed adesso non dice piu cosi.
permale la marcia avanti solo in alcuni casi riportati qui:

se nonci credi chiedi a Yanmar EU.... (l'importatore Italiano non capisce una XXXXX)

Grazie Infinity, proverò a innestare la retro e poi mettere in folle come da istruzioni Yanmar. In effetti rimettere in moto con la marcia innestata perchè non rientrava la folle non mi è mai piaciuto. Speriamo funzioni...

Se ricordo bene, nelle andature a vela, con la retro inestata l'asse gira trascinato dall'eica autoprop.

Per bloccare l'elica si mette la marcia indietro. Per metterlo in moto in folle.
Con tutti i motori,tutti con elica destrorsa fuorchè il volvo sinistrorso.-

Motore Bukh 36 sinistrorsa elica j.prop messa sempre retro per andare a vela.
