I just acquired a norwegian boat with Marna 5hp engine. It has a clutch with a lever and also a reverse pitch propeller system, with another lever. To operate the reverse pitch do I have to put first the clutch lever to neutral or can reversing be done when the engine is in gear? What is the procedure not to damage the system? |

It would seem to be unusual to have a reversing propeller and a disengaging clutch, the variable propeller has a neutral position. I don't see a problem going forward to reverse, there are no gears to clash. |

Clutch can then be engaged and disengaged with engine running, whatever position of the variable pitch? Is there any special care to take? |

On the Saab website you can find some manuals including a general paper about the operation of variable/controllable pitch props. These must be de-clutched for starting and stopping the engine but not for adjusting the pitch. You just should not make pitch changes at full throttle speed.
