Cruising Speed - Volvo Penta D1 Series Operator's Manual

Operation
Sailing
When sailing, set the control lever to astern if a folding
propeller is fitted.
If a fixed propeller is fitted the control lever should be
set to neutral or reverse. When using a fixed propeller
and sailing with the control lever set to reverse the
speed is slowed down though less noise is being
made.
IMPORTANT:
If a fixed propeller is fitted the engine needs to be
started and kept running for five minutes every fourth
hour of sailing to avoid problems with the transmission
system. The control lever must be set to neutral during
the whole procedure.

Cruising Speed

Avoid operations at full throttle for best fuel economy.
We recommend a cruising speed that is around
500-1000 rpm below the maximum rpm at top speed
(full throttle).
Depending on the type of hull, choice of propeller, load
and sea state etc., maximum revolutions at top speed
may vary, but should be within the full throttle range;
refer to the Engines section.
