I had a Newport 28 with an Atomic 4. I found the DVD from Moyer Marine on the Atomic 4 transmission to be extremely helpful. The first thing you will learn is that it is not a transmission! Next, you will learn how to adjust it, and what parts may need to be replaced. I also had some Don Moyer maintenance docs that came with the boat, they were invaluable. The Moyer Marine site also sells all the little parts to refurbish your engine. And there is a very helpful forum. And they can sell you anything up to a better than new engine. If you own an Atomic 4 you or your mechanic need Moyer Marine. Btw, I think the Atomic 4 is an under rated engine. Easy to work on, good parts availability thanks to Moyer, and smooth operation due to 4 cyl.

If so, I can use your help. I can't seem to find the position of components that will allow me to shift into Forward, Neutral and Reverse. I know the transmission will go into forward and neutral since I can contort myself into the quarter berth and move the lever by hand. The problem with the linkage is that I can't find a position to hook the shift lever on the shift shaft, connect the clevis end of the big curved push rod and create the motion that will move the lever. The normal position of the foot pedal was always with the control lever in the cockpit forward so that you lifted with your toe into forward, clicked down for neutral and then push down to hold in reverse. I have been chasing this problem as time allows in the slip since June and have not been able to move the boat all summer. I suspect that somehow (although I really can't say how this could happen) the shaft that the foot pedal and curved rod connects to has rotated so that it is trying to work backwards. Logic says that if the lever on that shaft was forward, clockwise rotation of the pedal shaft would cause the lever to push the curved rod back and reverse could engage. The same would be true for lifting up on the pedal to go into forward - it should pull the transmission shift lever forward. But, that shaft has the lever on the the aft side. If any of you have this type of control, could you look at your boat and tell me: 1. Is the lever on the pedal shaft forward or aft when at rest in neutral? 2. Is the curved rod curving up or curving down? Thanks in advance. Murph
