most likely a reman or a prior OMC motor
from the pics, the boat is trashed. the moss growing on the deck means the deck was done as a deckover at least once and that has failed.
my VW Jetta with the VR6 had the original clutch when I sold it with 240K of well-beaten auto-crossed miles.
the daily is the second dual mass flywheel car I have owned. and I will be looking for an aftermarket flywheel and multi-disc clutch.
Not a fan of dual mass flywheels. in theory, it makes sense. in practice, they rattle, cant be refinished and fail often. Im 42k on a new dual mass flywheel & clutch on the whip and its already slipping.
there is no auto-temp shut-down sensor.
you have an electrical problem.
does your ignition sensor still have 2 wires or was it upgraded to the 3-wire sensor?

Volvo didn't merge. They did a joint venture, which ended when OMC went out of business.
In the mid to late 90s, OMC drives were mostly Volvo drives.
Avoid anything Ford powered from the 90s
I myself would recommend boats from 2010 or later
