susan that's a pvc fitting - trash it.

What size is the thru hull and hose?  3/4 x 1"? Do you need a straight or a 90?

Thanks..I will measure hose..I will need a 90. Where do I purchase these? I am proceeding to check all fittings on all thru hulls.

Forespar doesn't make 3/4 x 1" hose. 
I buy alternates by the gross - I can drop you one via USPS (or hand deliver w/ a plane ticket!)

It would be better if you could route the hose and use a straight but after you check them all jus let me know what you need.

In addition to upgrading your sink hoses, you should really upgrade the hoses from your engine to the water heater.

From your picture, it looks like you have the original hoses.  Here is a picture of the hose I remove over the weekend on my boat which is the same year as yours. Good thing I replaced the hoses.  The one below[attachimg=#] probably would have blown this season.

Guys : When you replace any hoses that goes under the flooring (out of sight) and will probably lay on the hull - here's a tip: 
Slide a sleeve of pipe insulation or another larger hose over the primary hose to protect it from any chards in the fiberglass hull!!  Those chards will cut into the hose over time - as shown on the pictures!!

Lowering the tone of the conversation, I can report that I just disassembled the entire galley sink drain system on my Mark II with a view to cleaning out accumulated crud and improving water flow from the sink. I found that almost all of the greasy stuff was in the long hose attached to the thru-hull. So if you are feeling like you need a clean out you might want to skip disassembling the upper part of the drain system and concentrate your efforts on the major hose. It would save a lot of hassle and get round the possibility of disturbing the seal in the fittings attached to the base of the sink.

In my experience, the drain begins to plug at the water line level.  Any grease that goes down the drain will float there and eventually begin to plug the drain.  When I cleaned mine this spring, the 1" line was over 3/4 plugged.

What about baking soda and vinegar down the drain?  Two benign products that would not pollute the water? (but then again, with all the regulations, putting fresh water in salt water is probably illegal  :shock:)

Hot water at the end of the washing cycle when you rinse the dishes does it for us.  When I re plumbed last year we didn't find any accumulation.

One other idea is that you can use a standard old fashioned plunger/plumbers helper for sudden clogs or drastic slow downs on the sink, just remember that if you have a double sink, you need to plug one of them with a rag for it to work. BUT....you don't want to use a plunger on the head, it just won't work and you could damage parts.

Guys : About one a year I mixed a few oz. of bleach with some hot soapy water. The water level was just below the stainless sink fixture - sink thru hull closed.  Then I also "stirred/mixed" the water up a bit with a small plunger in one of the sinks  - keeping the thru hull closed.

I let the water mix sit over night, then opened the thru hull and let sink drain.  It was really cleaned out - the 1" hose to the thru hull looked clear again!!

I found a similar PVC elbow yesterday while trying to re-route my sink drain hose to accommodate the new water heater I'm installing. I sent an email to Forespar this morning (before checking here).  I'm hopeful that the marelon straight threads aren't screwed up by the pvc elbow's threads. My hoses are 3/4 so hopefully a 3/4 straight tailpipe will solve my issues.  Please pardon the mess. The old water heater was a pile of rust and I have not yet cleaned up after removal.

Im about to do this job...

Ken, are you still sourcing fittings?  I believe I will still need a 90,  but haven't made sure of the sizes etc yet.
