89 nautique 2001 speedometers?

I've lost both my Speedos on my 89 Nautique 2001. When I disconnected the tubes to the "fins", I blew air into them and a bunch of water flowed out. I reattached the tubes and drove the boat again and still nothing. Any suggestions on how to get them going again?

take the speedo out completely from the dash and blow a low amount of compressed air into the back. If the speedo moves then its good and your problem is probably a tube or the pick up..

Try cleaning the pick up with a small drill bit.
Use a bit that is smaller than the hole and turn it by hand.

You might need new isolators. They are a pain to change, you probably have to pull the gas tank, check everything else first. If you are unlucky your isolators might be frozen.
