I have a Perkins boat engine and the idle speed is too high

Customer Question

I have a Perkins boat engine and the idle speed is too high and so the dog tooth clutch gets 'angry' when going from forward to rear drive.

How do I drop the idle speed, please?

Page N 9 in service manual shows the adjustment.But it is just a mechanical stop that is moved to allow throttle to move to slow idle or raise idle. Here is link to 4-107 manual.----http://www.bluemoment.com/manuals/Perkins-4.107_4.108_4.99-WorkshopManual.pdf

Thanks for this help and thanks for the down load of the service manual. Could you also send me a copy of the service manual for the Z Drive.
