Amything done to the boat recently?

Start with the basis check all electrical connections including the big plug, also what about your water separator and fuel filter, kill switch

Was everything dead? gauges, stereo, etc.  When something goes dead like that with no warning, I usually suspect that its an electrical issue.  Check the battery switch. didn't we have a few guys have switches fall apart lately.

Sounds like a lot of hands, arms, feet, etc in the engine compartment.  I would give everthing a good look over, paying special attention to electrical connectors, especially

Just got time to look over the boat to see if I could find out what killed the motor.  First thing I found was the alternator plug was disconnected . Would this kill the engine and not restart.  It turned over fine . I do remember.  Turning on both battery once it stalled but it never turned over slow like the battery was drained. I think the boat would run till the battery was drained to kill it . So I just not sure that is all of my problems.  Will look for more .tomorrow

When battery gets low enough I think the motor will stall if the alternator is not supplying electric.  Would def think that is the problem

Yes, check battery voltage.  I believe VP ECMs are very sensitive to voltage.

once your alternator dies the battery drains and will kill a motor, even while running your engine requires electricity to keep running.  Start basic, check all connections, check batteries.

Talked to the shop today when the alternator does not show charge output the fuel pump is shut down for safety. 

So whenever however the alternator got unplugged that was my problem that my motor stopped running and I was tow in wish I would have looked at it while I was on the water simply plug the alternator in and it was fixed

It may have been accidentally pulled out while they were working on your trim tabs.

+1.  At least it was a quick, easy, and cheap fix.  Doesn't usually work that way with boats.

Guess who spoke to soon it didn't work  . I thought it was fixed till I went to start it in the driveway with hose attached and just turned over but won't start .

boat = bust out  another thousand. Took it in to shop will update you on the problems thanks

If I recall correctly there IS supposed to be a wire that is NOT hooked up to the alternator on a Volvo.   I believe it’s orange.  Google it to confirm specifically from a TSB from Volvo.  It also might have some black electrical tape on it.

Update.......

"Talk to the shop today apparently when they alternator shows no output the fuel pump shuts down for safety I was told by the shop so definitely was the alternator being disconnected to leave me out and having to get told wish I would have looked at it on the water was a very simple"

 

and some more info for reference:

On the VP's the electric fuel pump is powered by the alternator only when engine is running. There is a bypass that powers the pump when cranking. That is a safety feature so the fuel pump does not run on when the engine quits for whatever reason. Charged up batteries won't keep the pump going, has to be that 12v from the alternator, very specific circuit also. It is not the large gauge 12v output for the charging system at the alternator, it is in the wiring from that plug that came off. That is why the alternators for VP may be different than other cars or boats. Mercs use an oil pressure switch when fuel pumps are electric, it is off if there is not enough oil pressure (as in engine not running), with same bypass for power when cranking. You can short across those terminals on the Merc in an emergency, no such mechanism on the VP.

One should have noticed the volt gauge on the dash was not at 14 volts with the engine running Stalling out on plane can lead to a hydrolock condition ,you were lucky. If the gauge was reading 14V , the stalling came from something else.

Plus if the alt does control the fuel pump circuit it would not have run that long with the plug out.Could the plug have popped out leading to the low battery condition?

If it was my Volvo I would rewire it like a merc system with a oil pressure switch .That way you could lose the alt and still keep the motor running .

Alt dies = engine dies= STUPID

I have jumped out my merc fuel pump oil pressure switch so I can run the pump for 20-30 seconds to fill the carb bowls after a long sitting period.  Saves a lot of cranking.  Fires up nearly instantly.

I was frustrated with the whole thing and took it in . Turning out to be the alternator plug was disconnected from what I have no idea it is a pain to try to unplug when you want to so I have no clue what caused that part of this also there is a fuse for fuel pump on top of motor that was blown out all fixed . I was guessing all kinds of things that's why I took it in  and I was frustrated 175.00 to learn about the fuse location.  Lol

Who did this work for you? The [Shop] or yourself?

If the shop did, well!!

I started to look at it and found that the plug was loose and was thinking that it was the problem solving find . Till I tried to start and still wouldn't so I just took it in rather than guessing.  I just installed a swimplatform and trim tabs so I really didn't feel like working on the boat any more
