View Full Version : no reverse

I have lost reverse on my Borg Warner Velvet drive transmission.

Yesterday my son was driving and he said he was having trouble getting it into gear (forward). We thought at first that it was caused by the fact that the Morse control unit was loose (screws that hold it against the side panel stripped the fiberglass) It seemed at the time that applying lateral pressure to the Morse Unit and pin resolved the problem. Looking back I think we were mistaken. Within a few minutes we had no reverse, but we had forward. With the Morse pin in, I shift into reverse but just get an engine rev as I move past the detent for reverse(both on the Morse lever and at the Warner lever) With the engine cover off I could see the linkage move into the reverse position, (each time a click can be felt on the Morse unit as it moves into detent) and beyond that it began to move the throttle cable on the carb. I can see the pin on the Morse unit rotate. The transmission level was a little down so I topped it off with Dextron, but no help. The filter was checked about 20 hours ago and was clean. I took out the transmission cable cotter pin and put the lever in reverse manually but no good
We bought the boat last fall and wondered why the prop always spun slowly in neutral(cannot stop it with grip pressure, always same slow rpm regardless or engine rpm) some supra owners say that's normal, but I've heard it may be a sign of clutch plate warp.

My thinking was is this something simple like the oil level, the linkage, the Morse control unit(maybe simple but I can't see how you disassemble it), is it something I can limp through the summer with, or is it only a matter of days before I lose all transmission?

We live near Cooperstown New York., and the boat yards seem to only understand I/O's or outboards. Advice has been to find an Inboard mechanic but they don't know of any, so one question is can we do anything ourselves or is there a place we can take it too?

No Reverse,

Sorry to hear about your problems. I'm not sure by reading if you still have forward or not. I don't think it will matter. The borg trannys only have two clutch plates for reverse and seven for forward so it is likely with that old of a boat that they are wore. There is an off chance that it could be the control valve at the top, which puts pressure on the appropriate plates for forward and reverse. Since the tranny is going to be rebuilt I would replace the forward plates while you have it apart. There are grooves shaped like Xs on the plates that help them grip together when pressure is applied, those xs wear over time and they can be pressed together but the just spin. I hope this is making since, try contacting PCM or Indmar for an authorized inboard mechanic in your area. I wouldn't try the rebuild yourself, it is not real easy without training. I would love to help but I'm stuck here in TN.

Regards,

Jay Warren

Sorry to hear about your problem. I bought my boat from Silver Lake Marine in Silver Springs NY and they are excellent. Unfortunately for you they aren't very close but I would definitely recommend them. Another alternative for you is Brinson Marine in Syracuse. They have an excellent shop and actually used to be a Supra dealer way back when.

Here are the phone #'s and Contacts to speak to...

Silver Lake Marine, Scott (Service Mgr.), 716-237-5185

Brinson Marine, Pete Carolin (General Mgr.) 315-469-4867

Good Luck, with the shortness of our season here I know you will want to get fixed right away.
