Twin KAD300s won't start

I just purchased a boat in Miami with 2004 KAD300s DPX sterndrive. During sea trials the exhaust couplings ruptured and put out a lot of smoke. After this was repaired, the port engine would not start. All the belts were replaced at the same time. There was a couple days of standard troubleshooting stuff like replacing the fuel filters, changing fuel, etc. Fuel filters were replaced and finally the Volvo engineer was summoned -- fault code indicated a bad fuel injection pump. That was replaced, and finally the engines both started up. I also had a blower installed on a new circuit.

I had the boat trailered to Fort Washington in Maryland a week ago. I put both outdrives up before putting the boat down the ramp.

Both batteries were somewhat low, and engines would not start though they would turn over.

After charging, engines still would not start.

Separately, the starboard outdrive will not lower (but it will power up) and my Garmin chart plotter will not power on. But most of the electrical circuits seem to be working okay.

I sampled the fuel from the bottom of the water separator and didn't see any water.

Fuel injectors appear to have fuel at them (I had a general engine mechanic confirm this).

What should be my next steps to troubleshoot? Is there an instrument I can buy to pull codes? Are there any Volvo engineers nearby?

Thanks in advance. I was hoping the first day I owned the boat would be the best but it isn't working out that way...

sorry I left out an important detail: Engine turns over really well, but won't start.

I'm looking online to try to identify a Volve diagnostic reader but haven't found one that I know will work for sure.

Does anyone have a safe link to download a workshop manual for a kad/kamd 300 engine? Volvo website only let you have the operators manual.

1. Check the batteries before doing any more damage.
2. Stop trying to start with low battery power or else you damage to ECU. Those ECU cost about 5k each and have a minimum of one month wait time (if you are lucky).
3. Bring a Volvo engineer and let you explain how to start the boat.

Here's a manual for a KAD300 fuel system, I'll try and upload an engine manual too.

I had starting problems on a D6 engine and after lots of testing it turned out to be the fuel injectors. Would recommend James Troop from Liverpool.

1. Batteries were charged up pretty well on Day 2, but now the boat is on the hard and the marina left power on running them down again. I think I might replace all 4 batteries to take this issue off the table (and not worry about batteries for another 3 years). The power available on the hard is 15A power rather than 30A shore power and charging them each up may be a chore.
2. Ouch. For some reason, when I researched the boat before purchase the theme of the commentary I found was more akin to "reliable and easy to troubleshoot".
3. I'm near Washington DC if anyone has recommendation for Volvo engineers out there. (I do have one good lead).

There should be no issue charging batteries from 15 Amp shore power providing the batteries are healthy,
If the batteries are dead/damaged internally then charging them could be dangerous due to excessive heat and gas . So monitor batteries on charge for any signs of heat or gassing.
A dud battery can show a good voltage after being on charge yet it can have no energy to deliver.

He is charging at 110 volt
