Any advice on how to make the barbed fittings to the hose easier. Replacing the wire reinforced hoses to my AC raw water intake. Getting these lines off the barbed fittings wasn't easy, I suspect putting them back on won't be a treat either.

I have some boot lube I use for water ski boots that I'm thinking may help, but also heard that you can heat the ends of the hose with hot water and that would help.

Thanks!!
 
Use a hair dryer or heat gun on the hose at the fitting. It can take a few minutes but once it's warm the hose will come right off. Heat the new hose on both the inside and out before trying to install it. Get the clamps tight before the hose cools off and you will have a very tight fit.
 
Silicone grease works well if removing for maintenance periodically. Carb cleaner works to soften the rubber and make it slippery for a short amount of time.
 
Thanks! Stealing the wife's hairdryer for this caper may be my next challenge ;)

Yeah, I should have tried the carb cleaner bit when trying to take it off. Problem is these darn hoses are in the back of the bilge area and it takes me 10 minutes to get in and out (small exaggeration), Need a helper when doing these tasks so I can direct them to grab tools and supplies and send them back.
 
Heat gun (forget the hair dryer), a hose puller tool and work gloves. Get the rubber hose almost to the point it starts to smoke making sure you get it hot on all sides, and start working it back and forth as you pull. The hose puller tool can help loosen the hose on the barb. Its hard work for sure. Heat makes it a lot easier.
