Mercury/Mariner rigging hose diameter?

[kwik_uk]

Hi guys,

I've just ordered the cowl fitting (875266A 2) for my 1998 Mariner 135 (serial# OG740636) to allow me to use rigging hose.
I'm not using the Merc/Mariner rigging hose kit (32-825191A 4) as I need to use my own transom well grommets.

Can anyone tell me what the diameter of the hose is that Merc/Mariner use? I'd like to order some up so it lands when my cowl fitting arrives.

Thanks in advance

Mark

I got my numbers from this here

My experience with the fuel lines is 5/16 up to 115 hp (currently have that on my 90) and 3/8 for the larger engines. Measurements are ID so the OD for you would be about 7/16 to 1/2 depending upon hose. Quicksilver squeeze bulbs fit both size hoses. I just redid my hose and bulb so the numbers are fresh in my mind.

Hi Mark,

Thanks for the reply. It was the outer sheathing that I meant, like these pics below:

It's ok, I can see that lots of people use it, and lots of people sell the Merc kits, but it only ever tells you the length of the hose and never the diameter!! Really frustrating. Maybe it's to sell more full kits rather than just the cowl fitting. Or is that me being too paranoid? hehe

I'll just have to wait till the cowl fitting arrives I guess.

Cheers,
Mark
