that smell...

OK, new waste lines have been run and are in place (from head to tank and from tank to pump out)... but not hooked up yet. Temp here is below freezing and even though I got the ends of the hose pretty pliable with a blow dryer, there is no way I am getting them soft enough to stretch over the fittings. Do they make a some sort of stretcher you can stick in end of the hose and heat to expand and then put it onto the fittings? Will stretching enough to slide onto the fittings permanently widen the ends, or will they shrink back down when cooled?

Finally, should I use something like vasoline to get the hose on easier... vasoline is a petroleum product, is it not... I don't know if that would be the best choice.

Use K-Y. Really.
 
You can use the leftover K Y to lube up something at home too ?

You can get a muffler/tailpipe expander ant Sears or an auto parts store but I don't think you should have to stretch the hoses, just warm them.

Auto parts stores sell "radiator hose grease" to make it easier to put hoses on connections. That's what I used when I use to have to remove engine hoses to drain the block in my previous boat and it's what I used on my sanitation hoses when I replaced them. It's inexpensive and designed not to harm hoses.

When you put the hoses on the fittings push them all the way on in one motion, don't stop halfway, that makes it harder.
 
unless you have to get this finished immediatly, wait until the weather warms up a bit. turn the heat on the boat on to get it up in the upper 70s and leave it there over night.

a hair dryer or an industrial heat gun will work to bring the temp of the hose up when you are ready to fit it. use electrical pulling lube on the cold end of the fitting and a pair of leather gloves so you can hold the pretty warm end of the hose in your hand and work it onto the fitting with a twist and push method. i would not try to stretch the hose with a mechanical device as it might over do what you need.
 
Heat, KY, gloves and a hotair gun should do it. Don't use THE ADMIRAL'S favorite hair dryer. Buy a cheap one at the drug store. Up close for an extended period of time they can overheat and burn out. Then you have some explaining to do.
 
I have used this hose for pool lines and i find the easiest way to soften up the end is to heat up a pot of water to less than boiling. Insert the end for a minute or so and just slip on. it softens up fairly quickly. you will be able to tell when it soft enough.

You can buy a "real" heat gun at Harbor Freight for under $10.00. Why would you buy a hair dryer?
 
I impressed you got the lines run and ready to go. I know it's nice to finish a project but I this case there is no rush and it will be much easier when it warms up. I agree with Ron a $10 heat gun it a good invested it will come in handy both now and in the future just keep in mind heat gun get much hotter then a hair drier you need to be careful if you have never used one it is easy to over head or burn yourself never touch the metal end until it has had plenty of time to cool.
 
There is plenty of warm weather work to be done so I am trying to get as much done as I can now... especially inside the cabin where I have a ceramic space heater. Once I start something I like to finish it or it hangs over my head until it's done.
Re the heat gun... a $12 unit is on the way from HarbourFreight (thanks Ron).

On another note... found a place that quoted me the price of two custom foam mattresses... and noticed their website sucks and they are interested in redoing it so, maybe I get free mattresses and some money on top... we'll see.

And remember that when it's hot, be carefull of where you set it down so it doesn't melt something or cause a fire.

You're welcome. It was on sale a few weeks ago for about $9.00. I have another brand that I bought about twenty years ago for under $10.00.

This is also the tool you will use on your heat shrink electrical connections.
