OK, I think I have it. Last night I pulled out the dash so I could gain access to the backside of the speedo. Removed the holding bracket and was then able to pull off the tube. There was no extra length to work with and it was tight. Then disconnected the pitot pick-up tube. Lined a plastic container with white paper towel and had my wife hold the tube at the pick-up into the container. Set my air compressor at 40 psi and held that to the speedo end of the tube. No air flow at 40 psi. Being a degreed Mechanical Engineer and wanting to solve the problem, I increased the air pressure to 80 psi. Started by bumping air into the line until my wife told me things were spitting out. Removed a lot of brown slime and highly viscous fluids, along with some brown water. Continued to pressurize the systme until it was clear air. Got a lot more "snot" out than I expected. I suppose there's 26 years worth of accumulation. I bought the boat new and it's never been done before.

So, here's the next question. How do I keep this from happening again, or do I plan to make this an annual event?

Will try to post photos when I get them downloaded at home and put on here.

I think the equalizer is buried below the integral swim platform. No access that I can see actually getting at.

Now for warmer weather and the test run. Hope it works.

I use the air hose to blow the lines out every fall when I winterize.

^^^ what he said... but I don't pull the gauges every year - fortunate for indoor storage... old lines can cause improper readings. When I took my tubes off the gauges blew them out nothing came out.. but speedos reacted better when reseated new part of line...

I now have heated storage for the boat. I do still winterize it. When you blow out the lines, do you get much "stuff" out? Might just make this part of the winterizing process if the speedo works perfectly now.

I love it! Just use a bigger hammer!

If you attached a three way valve at an accessible position, you could make an access port that would allow you to blow the lines out each year with needing to call your chiropractor. If you got real fancy, you could attach it to an onboard compressor, blow out the lines while you're still in the water.

Photos dash removal and the "stuff" that came out of the lines. I have close-ups of the remains if you want to see it. Pretty gruesome glop.

James: Funny you bring this up. Did a search this morning and found a Telefoex GPS that lookied about perfect. This one is even better. You can see from my photos that I already have the cut out in the dash waiting for it. I have been using a hand held GPS with speed read out for the past few years. Need look at the price of this, but I think one is in my future. Thanks for the suggestion. Since all my sking is on lakes, it should be ideal.
