The  A4 forward gear engages like a clutch – you don’t want it halfway and 
slipping.
I would suggest the Moyer Marine board for A4 questions – lot of good info 
there.

Damien: ALWAYS Fully engage the shifter in both directions and make sure your 
throttle is off and the engine has dropped to idle before shifting.

The stalling is a bit harder to answer, not knowing any details about your boat 
or it's gear. I suggest you take a close look at your shaft inside the boat to 
see if it will turn freely when the motor is off and the tx in neutral. You may 
have a line from your locker wrapped around the shaft. Could also be something 
around the shaft or prop outside. If you can't figger it out, get a 
knowledgable boat owner to have a peek. Let us know how you make out.

I have a tranny question about my 1974 Viking 33 with the Atomic 4.   When you 
move the gear shifter up for forward or down for reverse, there seems to be a 
long throw of the shifter, almost like it varies the amount of forward or 
reverse propulsion – then I can apply throttle for speed.  Is this right – or 
should the shift lever either be in full forward (up), full reverse (down) or 
neutral (horizontal).

I should have asked this last summer when I started sailing, but as it was all 
new to me I thought I would figure it all out.  Now I'm not so sure.

Last evening I could only get a very small amount of forward propulsion and 
even less in reverse even with the shifter in the half way position.   Full 
forward shifter position (up lever) would stall the engine regardless of 
throttle position.  I had to limp back to the dock by playing with the shifter 
and throttle positions and restarting the engine every time it stalled out.   
Luckily there was no wind on the way back and the calm conditions for those 
last few hundred metres to my dock allowed me to make headway.  Even that 
distance of a few hundred metres took almost half an hour.

There was no noticable vibration to make me thing the folding prop was 1/2 
deployed, the engine was running great with no load and started fine when it 
stalled under full load.

What could be wrong - does this sound like a transmission issue ?

HELP

Thanks,
