If the firing order is on the intake manifold, it could just be from a reverse turning engine. Crank it and see which way it turns.

Do you mean yhe manifold could be from a different engine and the wrong firing order is on it ? Wouldn't that be funny if thats why he has not been able to get it to run !

Marinized engines have Stainless exahust valves

Marine engines can have stainless steel exhaust valves. They aren't *automatically* equipped with them.

The firing order should be standard with a sterndrive. Unless this is a very ancient engine, they all have Stainless exhaust valves.

When you stop the engine the exhaust is under water so you get some steam backing up.

So what happens when you shut the engine off and it stops with several of the exhaust valves open? Where's the steam going to go? It's going to travel right past those open valves and right into the combustion chamber/cylinder.

I suspect that the marine engines that do use stainless or inconel, (and no.....they do not all use stainless or inconel), use them for their ability to withstand higher temperatures for longer periods.
