Installing the Signet sensor paddlewheel under water

Has anyone replaced the paddlewheel for their speed sensor while the boat is in the water? I have an old Signet and have bought the replacement part, which has a pin similar to those on watch bands. I was thinking of diving the boat and trying to install it that way rather than pull the transducer out from the inside. Is this possible to do? Is there any trick to keeping the pin in place while pushing the paddlewheel into the slot?

Re: Installing the Signet sensor paddlewheel under water

If I remember my old signet correctly it is like most through hull speedo's. You unscrew the transducer at the through hull fitting and pull it out. Then just put your hand over the opening, pick up the new through hull and insert it.

There are two o-rings on the insert to keep it from leaking. Probably let in a couple of cups of water. Do not think you can even do it from under water.

Good Luck
