1998 1800 parker rail diameter

[Hook1fred]

I'm looking to purchase a couple smith rod holders ( clamp on style ) online and need to find out the outside rail diameter. Normally I would go out and measure myself but my boat is in storage at the marina and would be able to get there till next weekend. Anyone able to help a fellow parker guy out. Thx guys

Not sure I will be of help, but I bought a fits ups to 1.5 inch rail and it was two small, think I needed a two inch. Good luck!
