View Full Version : Lost Reverse... forward is fine.

Had the boat out all day without an issue. After it had sat for awhile, I jumped in again, untied it from the dock and backed out... reverse worked fine. Ran around the lake a few times, then headed in. As I approached the dock, I clicked it into reverse to maintain speed and swing the nose a bit... but nothing. It revved fine, but reverse would not engage. Forward was fine, but no reverse.

Once I was tied up safely, I disconnected the cable from the tranny, started it, and attempted to engage reverse manually, but still nothing. Any ideas?

The boat is a 1986 Ford PCM 19 foot Skier. I do not know which tranny it has... where would I look or how can I tell?

Fluid level? Water in fluid?

Happened to me last year.The reverse ring plates broke,both of them.
Skidim had them in stock.
Might as well change the damper plate while at it.
Good luck!

I would have said yes the other day after the malfunction first occurred, because I checked it shortly after..... but after reading a lot of different articles on here yesterday I'm not so sure. Is it true that the boat should be warmed and that it's critical to check it within 30 seconds of shutting down? If so, I have no idea and will need to go recheck it.

Easy enough job to pull the tranny and check it? Looks simple, but I've never removed one. I've owned boats before and have done plenty of work on both them and on different autos, but inboards are a new beast to me.

You have to lift the back of the engine about 4-5 inches to remove the transmission on my 94.
No,not a big job,only bolts to remove,no special tool if you just change the reverse plates.
Do a search here for transmission rebuilt.Good thread with a lot of pictures.
Low oil level would not cause to loose reverse.
Call Vince at Skidim.He is very knowledgeble and will tell you right away how to check if it is the reverse plates and how to check~replace everything.He s great to do business with!
Good luck!
Hurry,summer is short! :)

Edit:There should be a tag on the transmission with the maker and model numbers.
Or post a pix of it here,someone will bw able to ID it!

Thanks... I got my lazy *** down in the garage last night and checked it out. I guess I figured based on past practice with other items that it'd be a matter of crossreferencing serial numbers or something more involved.... but, nope:

There it was, proudly displayed on a great big red tag right on top and clearly visible:

Borg Warner Velvet Drive 1:1

I had the same thing happen to me last summer, bought a used Velvet Drive and worked fine the rest of the summer. About a month ago reverse went on this transmission. Rebuilt old trans and other than the lock rings it wasn't too difficult - the thread on TT about how to rebuild it is EXCELLENT. Seems to me all that needs to be replaced is the reverse clutch/clutches which is easy.

Check your model number, mine ends with -001 which means 1 bronze reverse clutch, model number ending in -004 means there are 2 bronze clutches and 1 steel.

Taking transmission out is kind of a pain though, get a $20 bottle jack from auto parts store to tilt engine and put a tarp over carpet/gunwales or you'll get trans fluid everywhere; at least I did the first time.

YDo a search here for transmission rebuilt.Good thread with a lot of pictures.

Maybe it's me... maybe its the search function... but I can't find the thread I believe you're referring to. I've found others that have been helpful with regard to removal from the boat, but no detailed rebuild thread.

Any one have the link?

I think this is the thread you need, though I didn't have time to go through it to be sure.

Thank you both.

1. for pointing out the thread, and 2. for finding it. I don't know if it's my lack of search abilities or just wrong key words, but it looks like a great thread to walk me through the process.

Now it's just up to me to commit to the process. The boat technically works right now, and it's warm out, so I almost hate to screw it up.....

if your going to rebuild - why not wait till season over?.... IMO i don't believe gears will be affected... it's skiing time - but I am not a trans expert...

Search functions on here are leave a bit to be desired. Fortunately there are enough people around here that someone usually remembers the thread eventually.

No reverse while picking up a skier could end in a terrible accident.
Add docking and loading on the trailer,not an easy task without reverse even for an experience driver.
Being on the water would not be as relaxing as it should.
:twocents:
Again,not a complicated job to do.With the help of a buddy who knows a bit how to work on mechanical things and this board,it s a 2 guys ,6hrs and 12 beers job!

Agreed... forgot to consider the compensation for the job ;) - I very rarely use reverse... very rarely..

I've been pulling skiers and launching my boat a lot without reverse this season and last season, so far so good - luckily haven't had to dock the boat yet.

I would be worried about lack of maneuverability in an emergency situation.
