The throttle on my Hunter 34 must be held in poition to maintain any RPM. It there a way to increase the friction in the cable or the linlage?

Throttle

I had the same problem on my 35.5, there is an adjustment somewhere but since the yard fixed it I'm not sure if it's at the pedestal or on the engine. I'm sure somebody here will know where it is.

The adjustment on our H28 was inside...

the Edson pedestal near where the cable wire connects to the throttle lever. You have to undo the compass from the top of the pedestal to gain access. See link that follows: http://www.edsonmarine.com/faq/index.html#q4 Terry

I made the mistake of

oiling the throttle linkage on my Yanmar 2GM20F while oiling the chains on the steering cables in the pedestal of my boat. Before that, I had great friction on the throttle; afterward it would slip. I finally added a cable clamp to the throttle cable near where it terminates on the engine. I tightened the clamp just enough to allow enough friction for the throttle to stay in place. This is probably not the best solution, but it seems to work.

Common solution...

Warren's solution is the most common one for keeping the throttle set at a desired RPM. Follow your cables off the back of the engine to see if one was previously installed. Once set to the right amount of friction, this solution has worked well on my H34 for the past couple of years.

Warren wins the prize!

That is the official Edson fix for the older cable setups without the friction adjuster.

Alternative.

I covered a piece of sponge with cardboard and masking tape and jam it as a wedge between the throtle lever and the binacle. It worked quite nice so I added a piece of string and and some velcro tape so when not in use it remains attached to the binacle. Think about a square block of 1" x 1/2" x 1/2". The problem that I see for adding friction to the cable is that eventually that friction is going to wear the cable down and break strands. Pedestals on the older Cherubinis are no longer manufactured and once the throtle lever mechanism looses it friction they are done for as there are no replacements that I have been anle to find.

beware of clamp tension!

on the stern side of the binacle theres a straight screw driver adjustment screw that clamps down on the shield of the throttle cable, and keeps it from moving with the handle on my 84 h34. i know it very well. i just replaced my cable over the winter, before i had to bring my boat to the ocean side, through hells gate. everything has to be perfect when you could encounter 7 knots of current passing by manhattan. this screw creates the correct tenision, but needs to be modified else it will break, like mine did. its made out of cheap white metal. i had one made of higher quality stock, and it holds very well now. getting in the binacle was a bitch, unless you have 5 year old sized hands. so dont break it in the first place. theres also a little clamp on the rear of the heat exchanger that crushes a bolt aganist the cable, but really looks cheap & has to be too tight to be effective. i dont know if it was supplied with the boat when new. youll have to ask a guy named rube......

J clamp works great.

The J clamp (cable break) will work fine. The one on my old H'31 has been on the boat for over 15 years and it is still on the original throttle cable. There is no reason to over tighten it either. The dealer originally installed a crusher on the cable, but I replaced it with this device from Morse. Also check under the compass, there is a nylon set screw that may add some additional tension. Sometimes this will do the job without the cable break. I believe that you boat has a Y/S Merriman pedestal on your boat.

EZ Solution

Get a tennis ball, stab it with a knife and slide it over the throttle handle. Friction with the housing will stabilize the throttle. It works (and was within my Hunter budget

Go to home depot and get a crosby clamp , tighten cable near engine,adjust to hold position . clamp costs about $1.50 regards ken
