NGK prescribes 'BUHW-2' which is perma gap - hence no gap to adjust

If you are running none permagaps
Rule of thumb

You will find a year identifier in the Brunswick Marine Download Center at http://download.brunswick-marine.com/download/main;jsessionid=105vjo07c1lcd?type=corp

Records are however incomplete for Belgian made models and I cannot find the number you quote!

From the same site you should also be able to download an owners manual.
Not always easy but you should find the manual there somewhere
