Re: [Amel Yacht Owners] Volvos.......

Ian and Judy,

   Sorry, I don’t have the same engine but hopefully someone else will answer that question for you.  

   In general, if your engine is reaching your normal full throttle loaded rpm in neutral but you are 700 short under load of what is normal, either the load is higher than it used to be or the power output has dropped for some reason.  You indicate that the prop is perfectly clean but perhaps it is not auto pitching properly for some reason?  There has been a lot of discussion on the Auto-prop (which I do not have on my boat) on the forum that you could bring up by searching.  

Best of luck and I hope that you get more help with this problem,

Hi James, ( or anyone else )

If you are on board and have the same 75hp  Volvo as I have, can you put on full revs in neutral and let me know what revs you reach ? 

Thanks,

Ian,

 The diesel engine governors that I am familiar with mechanically limit the engine RPM to a preset level by reducing the throttle setting.  If you are getting full revs. in neutral but not under load, I doubt that the governor is your problem.  I am sure that you will get more specific help here from others with the possible causes of your low revs.

Best of luck,

James

Bill,

  Do you have the 78hp Volvo with a governor ?  Can you tell me how the governor works--and what might upset it ?

Thanks, Bill,

 Alas....in neutral the revs do what they oughta do.

I will have to risk  trying the local Volvo agent.

Incidentally, to anyone who has had Volvo work done near Athens, does Mantalas Kyriakos have a decent reputation ?      Anyone else ?

Ian,

Will the engine run at 2800 rpm unloaded (in netural)?

If NOT, the answer is not fuel starvation (because that would take very little fuel) but a possible problem with the injection pump or speed governor.

If YES, then...  I am not sure...
