I have a 85 2001 500 hrs, recently the trans slipped (less than a second) while pulling up a barefooter, 30 minutes later it did it again, we ran another 2 hours with no problems The local mechanic I spoke with wants to rebuild. Should I run it till it stops or have it rebuilt now. Also, how much fluid does it hold?

Check the reference sect. and you will find in the PCM manual how much trnny fluid to use.

if you slipped it, a good indication is dragging in nuetral, the true test for drag is holding the prop shaft by hand at 1100 rpm, you should be able to hold it(safety note: don't wear a scarf while doing this test. if you cant hold it you have some warpage in the plates. you can put a gauge in the trans and check pressures, figure out the problem first. then decide if you need it rebuilt. start with the oil level first

Hi Eric
Please be more Specific
Are you suggesting the following:
Put the gearbox in nuetral.
Hold prop shaft
Bring Revs up to 1100 rpm.
Otherwise it is a recipe for riping someones Arm off.
Regards
Rob

Check the fluid level and quality -- burt, stinky, looks like peto-bismol? Top off the fluid or replace if needed.
Here's my opinion on the rebuild...
A rebuild is in your future. Even if the fluid was low and that was causing the slipping, some damage was done and you'll need to rebuild at some point.
If the tranny isn't slipping too badly, I'd continue using it through the end of boating season. (I live in Texas and we ski up to Thanksgiving sometimes.) I don't think anything else will break and need replacing if you don't rebuild it right away. That's my thinking on it. Maybe some others have a different opinion?

jimbo has it right, slippage, if not low on oil is possiby a sign of a problem, the oil should be nice and red with no burnt smell to it. dont try any additives it will only create MORE damage. the damage may be done alredy and like he said run it to the end of the season if you can to avoid downtime. actually in nuetral you should not have any drag at all, some boats do though due to oil shear in the clutch pack and the clearances set on the tight side. it is dangerous having any drag at all. common sense should kick in on grabbing the prop shaft, we use this test on our test stand with no prop shaft hooked up

Here's a question for you eric regarding a 1:1 borg warner
I figure it was due to my buddy using thewrong snap rings in the wrong place from what I've read, their more of a sim than retainers, but mine does creap forward some times when in nuetral, I can grap the prop shaft by hand and hold it and bring it up to 1100 rpm and still hold it do ned to worry about it?

you may get drag when cold from what's called oil shear between the plates and the clearance on these packs should be .018 to .053 on bronze and the same for fiber, I try to set them on the higher side by using thinner steel plates (which no one knows about) the packs are always on the tight side if you don't use some of the thinner steels. remember: you cannot adjust clearance on a 10-17 model unless you use the thinner steel. there are 3 sizes available .068,.058,.047. when set on the high side you always get a good clean nuetral
