Good point guys. I'll get a manual.
Thank you for that.
Do you know what the grey one is for?
I have a 2003 Mercury 140 2 stroke
Does anyone know if the black or grey tube is the speedo tube?
I think it's 1990ish. I'm not sure when they started production.
My 5m Hydrofield Jaguar does 40knots (WOT) with a 140 Merc.
