thankfully not in reverse. forward....
have an 80's EFNR long, and noticed the gear lever to be very stiff - the deckhand (me mate) must have forced it and now the rod is bent as well....
checked gear oil recently - ok - but was used in fresh water up until I got it 2 months ago and now in seawater...
any ideas folk??
where do i start..............
gears seized!

Check where the rod enters the top of the water pump housing. It is a tight fit and corrosion can cause a problem. (known problem area)
My EFNR has a grease nipple at the pivot point of the lever so one can assume this area needs lubricating (tho if the rod is bending it will be a bottom end problem) and last but not least check the oil content of the box.
If I remember correctly there is a threaded adjuster on the rod that may have been tampered with.
Cheers Hugo.

As Hugo has mentioned, the most likely problem is corrosion build-up where the selector rod enters the water pump/gear casing. the rod can be stiff as the best of times due to the action of the gearbox, but does this appear to be free or prepared to move?
Below the waterpump housing and in the actual gear case is a small seal where the rod enters - this is also a seizure point - you can only see this having separated the gearbox from the pump housing.
I can't imagine what, but is there stuff (debris/corrosion) where the propshaft enters the gear casing stopping the shaft moving back and forth, which it needs to as part of the selection motion?
Check these first before major surgery, which I doubt is necessary. Internals look a bit intimidating when you first take the end caps off, but is straightforward - only tricky bit is a pair of spring loaded sprags which are located in a saddle behind the rear cover. Rick.

Forgot to mention - you can be wrong-footed if the pivot bracket at the top of the engine has moved, and doesn't allow a full enough movement of the lever.
Look at this as one of your early checks - some had a little dowel to stop the bracket moving, but some were just nipped up with the big bolt.
If you need to reposition this, best way I've found is to have a suitably sized open-ended spanner to fit the parallel sides of the bracket (casting) where you need it, while you nip up the big bolt head. Can be frustrating trying to find just the right position! Rick.
