I took my throttle apart (mv2?) Out of my 86 advance to clean it up and powder coat it. Can't remember which linkage bolts to the throttle shaft and which bolts to the shift knob. Can anyone help me out?
-
I don't remember either but its easy to tell, watch the throw, the throttle is much longer than the shifter when you rotate the arm. Also the throttle only goes one way, the shifter goes through neutral, reverse, forward, watch it awhile, you will figure it out.

Alright then, this is going to sound stupid.... but please keep in mind I didnt take all my boat apart, some of it was done before I got it.
Where the cables run now is under the floor to the front of the boat and up through the holes behind where the foot rest is. Is that where they are supposed to go? or should they run up under the lip of the top of the boat from the back?
Reason I ask is... the throttle set up looks like the cables should be coming from the back of the boat somewhere, not from the front.
Any ideas out there? Anyone with a Advance that could shoot a few shots with the throttle in place to give me an idea of what I am missing here?
Thanks,
Mike

The control cables go forward from the throttle into the bow and turn, coming back aft under the floor, down the port side of the motor and turning up (vertical), next to the exhaust hose & water intake suction, and bending forward to the carb linkages. You should have plenty of slack in the cable to do this...
Ron & Dan would know better, but I think that accurately describes the layout!
-
Alright, I get where you are going. And that is the way it is setting up right now. The only thing is, what happens? Do the cables loop around and then go into the throttle? Cause my throttle was set up with the mounting part toward the back of the boat....... There is no way to mount them through the front of the throttle the way it is set up.
I know I am being a pain, I just want to do this once and get it right.
Thanks again!!!

The cable bracket on the back of the throttle should point toward the front, not the back of the boat. Like Joel said, both cables run forward from the throttle, making a large radious turn toward the holes in the floor behind the drivers kick panel, enter the bilge & run through the bilge to the back side of the engine then another large radious loop brings them to the trans & carb/EFI
-
Thanks Ron,
so basically, that crazy looking plate on the back that mounts toward the rear of the boat does nothing then? All you use is the 2 arms coming off the back of the unit for the throttle and tranny?
I need to take a few pictures and get them to Phil so he can resize them so I can post them up and make sure I am doing this right.

If you are still referring to the plate on the backside of the throttle it is very important, it holds the cable housings in place, one of them (throttle) has a special spring loaded "pre-loader" that allows full transmission engagement before throttle comes in.
-
I just need to call you or take it to a shop around here. The cables come in from the front of the boat. ...... the plate on the backside where the cables mount faces towards the rear....... so if the cables don't loop up under it to come in from the rear I have no idea what I should do.
Cables from front plus mounting plate facing the rear equals I'm still confused.
-
Are you referring to the cables on the back of the throttle at the chair... or the cables as they attach to the carb & tranny???
My tranny cable is black... the throttle cable is red ( that helps ;) Both go forward from the throttle and loop back aft under the floor. The throttle cable goes under the engine and loops back up from behind on the port side of the motor. There is a mounting plate on the rear / port side of the motor that the throttle cable attaches to (holds it in place) just prior to the cable attachment to the carb.
I mis-spoke yesterday about the tranny cable... it actually comes up on the stbd / front side of the motor & crosses over the front (held in place by zip ties on hoses) and down the port side of the motor pointing aft where it attaches to the tranny shifter on the port side of the tranny.
Hopefully, this helps to clear things up. I'll post some pics if I can find my dang camera...

Thanks Joel,
I know how the connections work to the tyranny and the Carb. Its to the mv2 throttle on the back plate under the arm rest where I am having the trouble. Pictures would be VERY helpful if you find your camera.
Thanks,
Mike

Alright. Here is the scoop. Someone tell me if I have this bad boy set up wrong. As you can see, the back plate where the cables should connect is facing the rear of the boat. The cables come in from the front of the boat. How do I get the cables that come in from the front to enter the rear of the MV2 without kinking them, or do I have the back plate facing the wrong way? or is something else wrong?
-
and a couple of more shots..... I think the plate is backward as Ron clearly stated before, but I got a picture from Brandon and his was set up this way..... unless it too was taken apart at some point and not put back together correctly
-
Plate is on backwards
-
thank you Ron! What I thought, but I wasn't sure. What do you guys think of the coating? I had a lot of pitting so I went with a texture black.
-
I like it, make sure you grease the spring loaded throttle pre-loader on the cable bracket, & double check the brass barrels for wear before installing onto the arms. That preloader is what allows full shift engagement before throttle begins, it must be adjusted correctly to do this, too much pre-load & you will have a "stiff" spot going into & out of gear, too little & you will advance throttle before trans is fully ionto gear.
-
I had a customer bring me his boat after it was summerized by another local dealer
it would start but would not shift or advance throttle ........... looked like those pics
and the cable just tucked in by it seemed like the tech just said F - it maybe someone else can figure it out
the coating looks good too

Mine was also on backwards. I turned it around and everything works out correct.
-
So the arms appear to be in the correct position?
I took the entire unit apart..... had to or I would have had grease all over the bottom of my oven. I re-greased everything up well, but will be sure to put some on the spring on the plate, thank you very much.
Brand new brass barrels waiting to be applied ;)
Thanks alot everyone. Sorry for any confusion I may have caused, but I was confused ;D She is not sea worthy yet, but closer and closer every day!

This reminds me of another story..... Back in the good ol days when boat builders & skiers were real men & didn't have no stinkin computers to test boats with I lake tested boats like this: no motorbox, no shifter, complete steering (if only one tester onboard) Hull & deck pinned, fuel system complete, no interior. Back boat into water w/o launching, pour a couple ounces of gas down the carb from a bottle, be sure trans lever is in neutral, crank until starts. Look for fuel leaks, water leaks, fire, if none present proceed. Manually shift trans lever into reverse by hand & back into lake, shift back & forth from neutral to forward & shift weight in back of boat to steer out of the launch area. Assume the testing position, rearward facing, butt on passenger seat DIRECTLY in front of the pylon, shifter left in forward, looking over your shoulder to see where you are going. Left hand on steering wheel, right hand on custom wood stick with wire hook on carb. throttle arm & slowly apply throttle while looking over shoulder. When 36mph is reached watch the wakes for symetry, if balanced wakes can be acheived by moving my shoulders only, we are good to go, if I needed to move my butt over port or starboard to acheive balance the boat goes back to the shop to adjust the trailing edge of the hull bottom. Gelcoat was added to one side or the other to correct this, usually with only one try. Then back to the lake to do all over again. Of course life jackets were optional but they made a pretty good seat cushion instead....oh the good ol days....
