Re: Larry and Mark......
Unless Larry comes up w/ one of those "Its this, I had the same problem", going to have to test a section at a time, IN THE SAME CONDITIONS AS ITS BEING USED. The throttle cable when you diconnected it, did you put some resistance againt the end while someone worked the throttle??? The wire in the cable jacket, will try and straighten any bends (rub the inside of the bend), unless there is resistance against it (rub the outside of the bend in pushing). When you try the throttle arm on the injection pump, are pushing the EXACT same direction (up!, down!, left, right, might not be a straight shot from the cable end) as the cable would??? You say pushing down on the arm frees it up. Is there movement??? The inside of the injection pump is a very high precision, high pressure pump. Dont go screwing w/ the guts of it. What about the throttle control itself, any corrosion??? Last haulout, I pulled the throttle control from Goldsmith's, Second Chance. Serious amount amount of rust. Cleaned it up, almost dunked the the entire guts in grease and lubed the cables. Now the engine vibration causes the throttle to back off and Bill had to use a velcro loop to hold the throttle.

Re: Speaking of throttle controls
Hi Guys,
Well, mine does the same damn thing..thought I had greased it too well! Heh..well, my way to handle it is to put a piece of S.S. rigging wire around the 1 in. tube of the binnacle safety bar, lead it back to the where the throttle is, put a little curl on the end so you don't shove it into your hand accidently, and then form a 180 deg. curl that would go around the throttle when it is in the most often used cruising position (about 2250rpm/5.5 kts for me). The throttle seems to stay put at higher settings, but at the frequently used point it will vibrate backwards over a 15 minute period. Irritating..I don't have a throttle brake either, but thought about putting one on the other end at the engine. It has not been a big enough problem to cause me to do this yet though.
Wish I had a fix, but Ihave the same problem there.

It's funny Macht Nichts does the exact same thing!!!!!! I've always figured that where she wants to be!!!!
Maybe we can get Cap. Larry to comment on this!!!

Re: Possible solution
I seem to recall on my previous boat there was a clamp of some sort on the housing of the cable which when tightened the proper amount would put pressure on the inner wire. I'm thinking that a mini hose clamp on the outer sheath of the cable could be tightened in the same manner. This is of course if there in not an friction adjustment on the shaft within the binnicle housing.
