I would suggest blowing from the speedo back to the pitot. Supposedly damage can be done to the speedo by uncontrolled compressed air into the pitot. Now, I've blown air into the pitot to test speedometers during troubleshooting but never let the needle go above 25-30mph or so.

If that doesn't do it, it narrows it down to the pitot, tubing, brass balance (also heard it called ballast) tubes, or the speedo itself. Hopefully not the speedo as they don't make those Airguides that were original in a 94 anymore. I had a bunch of trouble with some 85 MasterCraft speedos and it ended up being the pitots...didn't look broken, but they weren't functioning as they should of. Replaced with the new venturi style pickups from skidim.com and solved the problem.

And before you take anything apart, clear the pitot hole with a safety pin just to be sure there isn't something obvious plugging it there. Be sure to post your progress and ultimate solution to the problem as well.

You have 3 speedos on there right? 1 in the computron and 2 regular types?. Is it both speedos or just 1?

I upgraded a 94 Echelon with the venturi style pitot tubes. Well worth the change as accuracy and plugging much improved.

I use to keep a small hand pump with a short piece of tubing attached to it, on board. I would pull the tubing off the back of the pivot, attach the short piece of tubing from the pump and have at it. There were times that I physically could not pump the pump. When that happened, it was time to get out a needle and clear the pivot manually.
