Chuck
Thank you for your prompt and informative response......and the
website....the tech bulletin(s) I was trying to access were not available.
From one of the diagrams on the website you provided, it appears the
'tension control adjuster' could possibly be under the compass. Going to
the boat this p.m. and will remove the compass and investigate.
Getting the clamp on the throttle cable adjusted in a PITA.....mine is
located in the engine compartment....enough said.
Not sure I am brave enough to do the 'drill and tap' alternate
solution....if there is no 'tension control adjuster' I might just live
with the clamp on the throttle cable and a small bungee cor/d I
sometimes use to hold the throttle in place.

Howdy Rob,
Early versions of the 870 engine control didn't have the throttle tensioning screw
located on the starboard aluminum "boss" on the control casting. The common
option to reduce the effect of the throttle return spring was to install a cable clamp
around the throttle cable with just enough tightness to create friction and keep the
throttle from closing. My Landfall 35 has a different control (model 737) than yours but
has the same clamp arrangement. Getting the right setting is a bit of a trial and error
arrangement and will vary with cable wear.
As an alternate solution, you can drill and tap the casting to accept a 1/4"x
3/4" 20 tpi thread bolt or screw and bear down slightly on the plastic collar
through which the throttle lever runs on the control. Its not a bad idea to replace the
white plastic collar when you do that. Keep in mind that you can adjust or remove a
clamp mounted externally from the pedestal if it is located in an easily accessible spot,
but having the adjustment inside the pedestal requires removing the compass to make
adjustments over time. (More work, yes, but it is also an excuse to lubricate the
pedestal wheel shaft bearings and run some 30 weight oil over the steering chain with a
rag and check for broken or worn teeth on the sprocket, you know, the annual steering
inspection and service that virtually nobody ever does...)
I also know that Edson recently revamped their website and their tech bulletins
weren't available online for a while. They're up and running now and the one
you need to reference is here:

Hope this helps... give a shout offline in case you need more info.

Subject: Stus-List Edson Throttle Tensioning Screw/Bolt
I am pretty sure my boat has the Edson #870 pedestal....SS throttle on the
starboard side, SS gear shifter on the port side. I have been searching
the Edson Marine website to learn about the 'throttle tensioning screw/bolt'
but have had no success accessing any information on it......specifically,
where exactly is it located and how do adjust the tension on the cable so that
the engine holds an RPM.
My throttle currently has a 'clamp' on the cable that can be tensioned however
if there is a better way to properly tension the throttle cable, I would like
to experiment with that.
Chuck Gilchrist, I suspect you might have specific knowledge of this..... if
you read this, your input would be greatly appreciated.
