I rebuilt my 4.108 Perkins
myself and that included the doing up the injector pump
and injector nozzles.
I think the pitch
of the prop is 18-it's supposed to be the standard size for this boat I think.
in nuetral seems to rev out to about 4,000 RPM
Under load the maximum revs is about 1800 and the boats doing about 6 knots or so.
When under load it's easy to reach 1800 rpm
at not much throttle but when I push the throttle to maximum there's no difference at all?
I then loosened of the injector adjustment by 1/4 of a turn to give it a little more fuel
and lower the pressure to open the nozzles but still no difference.
Is this normal or do you think the prop size is to big?
Anyone else have what I've got as far as engine
, prop and boat go at all?
