borg warner troubles???

you can loosen the lock ring and tighten it up, but you should replace the flax packing. (available at skidim, boatersworld, westmarine, ect) cut 5 circles and offset the gap 180 degrees for each piece. 1 drop every 10 seconds and no drips when the shaft is not turning is what you are shooting for.

'harshness' in reverse could be any number of things. do one thing at a time, but change the tranny fluid, see if the prop is bottomed on the taper of the shaft, check the shaft at the flange for slop and check the engine alignment/engine mounts.


if the clutch pack needs replacing, mark at marinegears has helped me with parts for the 71c b/w in the 72.

Does the boat run smoothly? You might want to check your plugs. I know that sounds stupid, but last year I thought I had a transmission problem. The boat was running very rough and to top it all off, when I would put it into reverse, it would make funny clangy noises like something was banging around in the trans case. I found out that if the boat has even 1 fouled out plug, it will cause a mad chain of events. I replaced the plugs and poof......perfect shifting.

did you get the shaft log tightened up?

when you put the boat into reverse, you are pulling on the two small set screws at the prop shaft flange. these will cut a groove in the stainless shaft over time. you might pull the shaft out and turn it 180 degrees if the bore is still tight.

run it in forward gear and mark the joint with a felt tip pen. give it a bump in reverse and see if the mark moves away from the flange.

the only water around here that isn't frozen is the back of the toilet. i'm just kidding, but it's been a cold one this year.

elberts double taper shafts are 'the bomb'. anyone with a worn out single taper should pony up and get one.

since all the vibration threads have surfaced, shorting the shaft to get the prop closer to the strut, as bill has recommended, is next on the meal plan.

i think i'll do a little experimentation on the torio this summer. the prop is a good 6" behind the strut even though the v-drive box has been move forward. it has a 14" diameter prop a couple inches clear of the hull, so i should have room to play.
