Re: Getting hoses off

Boat 3, exhaust hose. *##*&** exhaust hose. I think it was 4" diameter, maybe bigger. It was big, it was long.

Step one, enter the coffin that is the cockpit locker lying on your back and of course remove the side panel to get access. The hose could only be described as the size of a boa constrictor that originated at the wet muffler and ended at the stern fitting. It would not come off. Heat, hack saw blades to tear into it, diagonal cutters to cut the spiral wire, more heat, more hack saw blades, one long day. I was much younger then, wouldn't even try it now.

Wrestling a boa constrictor in a coffin.

Good luck "out", rooting for you!

Re: Getting hoses off

I apparently have a melange of size for hose "barbs" and hoses... Some of them may be metric???? Or maybe the spec on ID is off. I bought barbs from Amazon supplies and they do vary.

Many times the hose will not even go on the barb without heat. So when I do heat it and it softens so that it can be pushed on... invariably when it cools it shrinks tight to the barb and the clamps is not holding it on at all, But I do use a clamp never the less. A hose that slips on easily will likely leak and is the wrong size for the barb.

pay attention... someone's life depends on it

Re: Getting hoses off

Combo of heat from hair dryer, vise grips on hose and using two progressively larger flathead screwdrivers got it done. Had wife hold vise grips lying on her belly with head out of the way. Light on flexible stork. Then while twisting hose used both screwdrivers together and twist them. That progressively pushes hose down as you go to bigger sizes. Once part tight on barb is now a fraction down with additional heat and twisting hose came off.
It needed 5 hands to do it.
WOO HOO!!!!

Thanks to all for your suggestions. Used a bit of each.

Re: Getting hoses off

This is one of the most annoying pain in the butt things to fix.

Remember... no matter how long you think it will take to fix or do the repair... it will always take 3x as long and cost 2x what you estimated. No 1 rule of yacht maintenance (unless you are Maine Sail )

Re: Getting hoses off

After fedex, brokerage and fees. $525US for the new pump. That part adds salt to the wound.

Re: Getting hoses off

Generic equivalent (marsh) for a Dometic . $345 pump, $85 brokerage, rest fedex from st. Martin island water world. Gets here Monday. Then once thereís a break go to st anse. Called and emailed. No pumps there in Martinique.
Getting a grandson flying down. Wife wants AC for him. I could sweat and she wouldnít care. Normally we donít use AC. She glows, men perspire, me and the horses sweat according to her. Sheíll only change the sheets if I shower regularly. I like clean sheets. Know mark thinks like Neapolitan but apparently Iím not Josephine. Of interest when thereís just men aboard they say Iím the least stinky.

Re: Getting hoses off

Ive gotten hunt so many times taking off hoses. If you don't smack your hand on something you cut it on something else. I now have gloves that are mostly for doing hoses, but if they dont come off pretty easy i cut the bastards.

Don't blow air up my rear, be useful and blow it at the sails!

Re: Getting hoses off

To late to be of practical use but you could consider cutting the hose and the splicing in some additional with a barb to barb joiner.

I have used a variation of this technique effectively. Wrap the hose in a towel and pour the boiling water directly on the towel. Keep applying hot water until the hose is soft enough to remove.
