I have a 16' bowrider with a 3.0 Volvo 4 cyl. with 40 engine hrs. total. Over the summer we ran aground in some mud and soft sand going idle speed, the engine alarm went off and we continued for about another 3 minutes to move from the traffic lane. After turning the engine off it woud not start. The mechanic at the boat yard tells me I have to re-place the engine. This boat is about 3 years old and is used very little. He hasn't said what is actually is wrong with the engine only it needs replacing. Does this sound wierd.

It sounds wierd given that you apparently did not receive a full analysis re; what the exact issue is. At least not from what I just read.
The mechanic should have given you a more full analysis, IMO.

However, I think that there is some information that is missing from your post!

In this three minutes of running after the alarm sounded, what temperature did the engine reach?
Was it excessive?
Did the engine shut down on it's own?

If the water intake allowed mud or silt to restrict cooling, you no doubt experienced some over-heating if you continued operating the engine.

You also do not mention how it won't start!
IOW, will it turn over, but will not fire?
Will it NOT turn over at all?


When my dad was teaching me to drive, he told me that green means go...... yellow means stop..... and red means Stay Stopped. :)
The alarm is like the yellow and red traffic lights..... it means STOP..... and it means STAY STOPPED, until the situation is assessed!
 
We experienced an overheat/shutdown on a Mercruiser (due to pump failure) which resulted in hydrolock. We purged the saltwater with the plugs out and got her running again with no apparent permanent problems for 2 years.

Rick - I like your driving instructions. I learned red means stop, green means go and yellow means 'If you hurry up you can make it'.
