Hi all, I have a bolt and rubber spacer missing from the rear of my hydrofoil. I have removed the opposite spacer and noticed it has a slight taper, 4mm to 3.5 mm. I am going to source rubber for the replacement but am unsure of the importance of the taper. Thoughts on using 4mm rubber washers please? The foil doesn't have any markings so unsure of make but its on a 2003 Mercury 75 2 stroke.
Cheers
Rob
