Here is a link to a picture of my boat. As you can see the deck is similar. The forum no longer allows pictures that big so I had to use a link. jim http://www.hydrodyners.com/forum/download/file.php?id=1507&mode=view
Were you getting an error, Jim? The only limit in place is 1MB, so the files don't get ridiculously huge. It no longer checks the dimension of the images at all. Your pic is only 804kb, so there shouldn't be any issues. I was able to upload it.
The measurements are the same. You have an 18 ft Dyne skier. Basically the same boat you mentioned skiing behind in the 70's. Hydrodyne's production of that boat stopped in the late 70's as far as I know. The modified I/O deck makes a handsome boat in my opinion. I am wondering if the left throttle was used so the observer could control the speed. jim
Yes, I was told that was the purpose of the center throttle, it just didn't work well for us. Do you have any more info or close up pix of the throttle return spring you mentioned? It sounds a lot more budget friendly than a new throttle assembly. I've accessed markbano's pix, but am on a pretty steep learning curve as it was always my dad who took care of everything mechanical while I rode behind the boat and assumed it would all go and operate as soon as the key turned
I don't have a picture of that spring on a Merc, but it is the easiest one to rig. On the left side of the motor the throttle cable fastens to a large arm. The bottom of that arm moves forward as the throttle opens. The spring goes from the bottom of that arm to a fabricated tab on a headbolt or somewhere on the back of the motor. It is pretty low tech. A long spring is desirable with just enough tension to take out the play and weak enough to not annoy you. jim
Thanks - We'll take some measurements and get our hands on a few springs over the winter. Back to work pretty soon; lake time is about over.
I suppose that it is possible that the boat was built in the 60's as an I/O when the external number was not required and later converted to an outboard. I sent the pictures to Tom Miller to see if he can find out anything. jim
