Mercruiser 5.7 Cutting out when shifting

[flystrong]

I have a 1991 Sea Ray 220DA with a 5.7 Mercruiser, Ser No: OD501645 & Model No: 4-57B100DS. When shifting in and out of gear the engine is dying. I am aware of carb icing when the engine is cold but the problem occurs even after a long run.
Could the problem be that I am to tentative when shifting into gear at such low revs that the engine is stalling when engaging the dog clutch?
The engine usually idles at around 900 rpm and when shifting into gear to manoeuvre I am probably only running at 1000 rpm.
Also what manual should I look at buying, as I have heard some are better than others?
Thanks
Richard

Ayuh,....

The Odds are that your Lower Shift Cable is dragging,+ Needs Replacment....
And,....
Your Idle is Way Too High.....

It should be 650/ 700rpms at idle in gear......

That could be a very real possibility. When shifting in there is quite a clunk is this normal or could that be the Lower shift cable also?

The loud clunk is because of the high idle. That's really hard on the drive gears and clutch dogs.
For a drive manual, do you have an Alpha I or an Alpha I Gen II outdrive. The changeover was in 91 and you could have either.
