ok, since I dont see a separate forum for the binnacle controls, its going to go here. If this is the wrong spot, mods, feel free to move it.

Boat is a 1980 Galaxy V-hull, 16 foot with the Mercruiser 120 setup. Binnacle controls are Hi-Lex controls. Originals were shot. Wouldnt move out of gear, and the internals were severely worn. Trying to be "economical" (read cheap...) I got a similar set off of Ebay. Cables fit fine, but the package doesnt really want to mount under the rail as the bolt pattern and standoffs are a bit different. Since the original controls were installed by a 500# gorilla with a sawzall, there is a massively oversized hole where the controls mount. Needless to say the new unit is a bit "sloppy" and I am not really pleased with the appearance, nor the slop. My thoughts are to take the through bolts on the controller that sandwich it together, remove them and install longer bolts to act as mounting studs to the frame of the boat. I really dont see another way to mount this in any form of an aesthetically pleasing manner, and this will solve the issue of a very small bolt circle holding the unit in place. The bolts in question are the three fresh hex head ones in the forward corners, and behind the control shaft. Plan would be to remove these one by one, insert from the back side (where the nuts currently reside), put a nut on the front side where the head currently is (to hold it all together) with the remaining length acting as a stud to go through the mounting area with another nut (and a washer) on the outside to hold it all in place.

Short of binning the damn thing and buying new (not in the budget, but hey, its only beer money, right) does this seem like a reasonable manner of mounting the control?IMG_0318.JPGIMG_0319.JPG

alright just a fast update for those that may be interested......

got some 1/4-20 coupling nuts about 3/4 inch long at the local hardware store this morning, flipped the side where the bolt head is, and buttoned it up. Got it mounted to the boat, and cables hooked up with no issues. New throttle and shifter works good. At least this one doesnt get stuck in gear when using it. Sometimes just a bit of Hillbilly Engineering is a good thing.

next up, Ill get some 1/4 inch ABS plastic and make a bezel for it to pretty it up (and give me something to splash proof it with). but that will come after splashing this thing.
