Hey guys,

I want to replace the cooling hoses on my Mercruiser 502 Mag. The hose going from the stat housing to the top of the oil cooler has a slight drip and I want to replace it before failure occurs. I figure while im at it replace them all. Its a late 90's to early 2000's setup with V belts not serp.

I've had good luck with the Wonderflex marine hose.

It's available at most industrial hose or hydraulic suppliers.

As long as there is no built in end to end dia size difference in the custom molded rubber hose.

Wonderflex is wire reinforced.

why not just put the serial number into the various sites and get the OEM part?

Yeah, dozens of sites with the exact OEM replacement, which is what you want with any formed/molded hose.

Most need to be ordered.
Had 1 that was almost a month to get.

I suggest you order them right away.

This boat is FAR from original I have no idea what the serial number is on it. I know its the hose that goes

from the stat housing to t he top of the oil cooler,

Thank you, I actually found it at wholesale marine and ordered it. Its a little bit of a lead-time as its not stocked anywhere so I hope the current one holds for a week or two lol. Little rubber tape and a hose clamp. It works for the road kill crew lol

I've bought tons of parts from this seller:
