Not sure about your Pearson, but a lot of boats (Catalina being one) have the glow plugs wired through the instrument panel with fairly thin wires - of course old and corroded by now too. This means that the power to the glow plugs has to pass the instrument panel. The fix is to use a solenoid so the current doesn't have to pass through the instrument panel and wire the glow plugs with a larger gauge wire. Anyone who is in this position and has made this improvement has improved cold starting by a large margin.
You state that you had "no response". Do you mean the engine didn't turn over at all? If the connections are good the engine should turn over slowly at least, even if it doesn't start.
If it is the two Deka batteries I recommend replacing them with one good start battery -you don't need two and it shouldn't be deep cycle. I would stick to a flooded battery as your house bank is of this type and this way they will have the same charging requirements. Checking wire size and connections is a good idea as well as it may require upgrading.
Hope this helps.
