The never ending project that is my friends' Statesman 305.

Last summer, one of his DP290's physically would not come out of reverse. As in, when we removed the selector from the linkage, we couldn't push it back into neutral.

We removed the selector cover and quite literally thumped the cone back into neutral with a piece of timber (you couldn't make this bodgery up, but that's the kind of boat / personality we're dealing with). I warned my friend that this would come back to haunt him, but he just wanted to chance it as it seemed to magically free up.

Fast forward..... Same engine / out-drive...
Neutral fine
Forward fine
Back to neutral fine
Will *NOT* go into reverse. Physically. As in, as before (except the opposite), we cannot push the selector into reverse.

So, this is clearly an issue with the cone, or something in the upper unit of the leg.

If you were a betting man, what would you look for, and what parts would you tell him to order / replace?

BruceK - Nope, last season when we removed the selector dog, it was free.

It was as if the cone itself was stuck in place. We had to hammer it down with a timber wedge. Basically, as if the cone was stuck on the shaft.
 
The selector does not so much put it in gear as allow it
The shaft the cone nuns on has a spiral that helps it engage
It will either be wear in the selector face or in the cone
Full strip down of the top unit I suspect
 
Can you get the cover off to check if it is the shift cable or the leg internals that is the problem.
Seem to recall that shaft needed to turn a little to allow cone to engage. ?
Was shift cable connecting to shift mechanism "adjusted" during any repair work ?
If not correctly adjusted pretty sure I could engage forward and not astern or perhaps vice versa.

I suspect it is the cone not wanting to go up and down the shaft.

When you 'selector face', do you mean the bit of the cone that the selector dog sits into (and then nudges, go to into gear). OR, the actual selector dog itself (T-Piece looking thing)

It's internal. Can't push the selector dog into reverse by hand, even when it is removed from the linkage (Well, that's the way it was last time. I'm not a betting man, but i'll bet it's the same this time also)

Last year the the out-drive would not come OUT of gear. Only came out of gear by hammering some timber on the cone (tried wiggling the props)

Now it won't go INTO reverse, no matter what we try,

It's something internal, along the lines of the cone or the shaft.

No moving of the props etc. will do anything... we've tried all sorts of different things.

It's as if something is stopping the cone going up or down (can't remember which it is for reverse)

The selector needs shimming up. Simple job

Hi VP, thanks for the info.

When you say above, do you mean the selector dog housing?

Or the actual selector (arm) itself? When we removed the whole selector dog (using that term as it was used above!) housing, the arm and the housing was all one piece... don't remember any shims?

What I do remember is the shims between the Upper / Intermediate Housing.... they were in bits (damaged!).
Item 36 here: PentaParts zoom
I warned my friend not to re-use them, but you have to remember, this is a proper pie-ball, muck-savage project / boat that, at this stage, is just a bit of a laugh for us to mess about with.

So it turns out my friend hadn't actually tested the reverse issue without removing the cable from the linkage on the out-drive.

Out-drive goes into reverse fine.

This is a 305 Statesman, hence fly-bridge, hence dual controls.

When you try to move the throttle into reverse (either station), it just won't go in... hits a brick wall. You can hear the dual-station mechanism (starboard side, engine bay), making noise. It's as if something is stuck on the dual-helm mechanism.

I think i'll let my friend rattle on with this... it's almost as if a whack of a hammer would sort it.

why should he try it he has you
 
Start by putting both controls Into neutral and checking the mechanism for linking the gear cables the throttles should both go to same point with a lost motion attachment
The DS UNIT may be either morse or Volvo both with kipper shaped plate or third option a two cable on slide mechanism
You can not move both controls at the same time and change over is done at nil revs in neutral
Put the controls in neutral and adjust the cables so that the backlash is equal the ds units may have holes (6mm?) that allow you to hold them whilst you adjust them.
 
So it turns out the culprit was the reverse locking mechanism on the out-drive.

When you go into reverse, a pin pushes forward and in turn pushes (up or down) a latch. This latch was seized. Freed it up with a hammer and some penetrating oil. Warned my friend to take things apart and either clean up, or replace (fat chance). It had been bodged before... rounded heads on the allen bolts.

Just an FYI incase anyone has the same issue in future.
