I'm looking to replace the hoses for the raw water cooling system on my Universal 25. Does anyone have a link or know off hand what the dimensions of the hoses for the cooling system might be? Thank you for the help.

Link for hoses
www.marinedieseldirect.com, click on Universal, then M25 and you'll have to read the all of the different groups.

hose diameter
The link was a lot of help, but I need the hoses diameter and length for the raw water side. If anyone has a M25 and has messed with these hoses, please throw me a bone, my hoses are old and worn and hard to get a good read on..I'm thinking 7/8".

I thought that's what you'd say
But here's the rub(s):
For the raw water inlet from the thru hull to the rw pump: we don't know where your strainer is, so we don't know how far it is, what the course the hose travels, so don't know YOUR specific length.
For the rw to the HX, we also don't know what pump you have and what the screwed in connection barb sizes are although they should match the (undocumented) HX port size.
From the HX to your exhaust riser, the HX group doesn't show the connection sizes on the ports, and I recall on our M25 it's 5/8 inch for that hose. I know that because of the size of the siphon break and the inlet size of the exhaust riser mixing elbow.
I recall the rw being 5/8, the hoses to the hot water heater are definitely 5/8 (except for the short 3/8 off the stat and fw pump), and the fresh water hoses being 7/8.
So, you have a couple of choices, since I figure you're asking because you don't have access to your boat which would allow you to measure them yourself. When I first did this on our boat, I thought it would be necessary to measure exactly, and recognizing the cost of hoses, quite important.
That's not the case, because I figured if I got more hose I'd have enough left to keep on the boat for future use, and would record those lengths for the next time (which I did for MY boat, NOT yours). Sometimes the leftovers are long enough for reuse, sometimes not.
1. Do a ballpark estimate and you'll probably find that the longest usual length of hose you can buy from a store is about 25 feet, leaving you leftovers.
2. Try to figure out each individual length and have the store cut it for you. The real downside of this is that once cut you can never return it, and if even a tad too short, it's useless.
Your boat, your choice. Good luck.

great response
you're right, i'm offshore right now working and my boat's at the dock. i was trying to get everything in order when i got off on wednesday to save some down time on the boat, the weather has been gorgeous and i want to get the boat back out as soon as possible. i replaced the hoses on the fw side already, just with a little trial and error, i'll do the same thing this go around. thanks for all the help, this is a great forum.
