I'm looking for this as well, for a 2003 3300 SCR. Corinthian Marine's site (https://corinthianmarine.com/
) says they have a templated for a "3300 SE MV". As far as I can tell from looking around, I *think* the templates may be the same. I sent them a note last week but never heard back.
If anyone manages to track anything down, I'd be interested in what you find out.
