I’ve got a Borg Warner velvet drive 72c 1.88 (Its possible it is the 71c, I don't remember) coupled with a crusader 5.7 300hp engine. On the last trip out when stopping at a fishing spot after putting it in neutral and then back in gear I hear a sound coming from the tranny. I checked the fluid and did not get a reading on the dipstick. The noise sounded “clackety clack, clackety clack etc” the sound disappeared in neutral and was present in fwd and reverse. The boat would still go into gear fine. After returning to the dock on one engine I filled up the tranny with ATF and the sound disappeared. On the next trip I made it out about 2 miles and stopped the boat to listen for the sound and it was back, but a little quieter. I returned to the dock on one motor again. After checking the fluid level, it had not leaked at all. On a 3rd trip to diagnose, I could not get the noise to return while at the dock running in fwd and reverse, but I did not run it outside of the dock. I’m confused. Could something change when the tranny gets hot? Does a dampner plate exist on this transmission? The transmission is not slipping and will perform fine at all speeds. I only notice the noise at RPM’s below 1500. Any help would be appreciated. Also, is there any repair facility recommended that would service NW florida (Steinhatchee,fl).
