I was going to replace the pilot tube pickup this week cause ti was broke off. The tube comming down from the top of the transom has 3 wires in it, it is not hollow. So that tells me that I dont have the pressure gauge, but what do I have? I have never seen this before and where do I get the parts for it. The interwebs arn't exactly working good for the search. |

Most Four Winns had a paddle wheel speedometer pickup, not a pressure type. It Electronically counts rotations/speed of a little 1" paddle wheel at the transom. Has the advantage of working at low speed, and being relatively weed-free. Sorry, but I'm not sure where to get a replacement, other than Four Winns dealer. |

Thats what I was kinda thinking, called the dealer and they said it is gonna be hard to find parts for my 23 year old boat. This kinda stinks. |

http://www.boatersworld.com/product/MP63487342.htm $182.00 You have to pull the new wire through, if you try to splice it, you'll ruin it. |

Hmm my '88 has the pitot tube style, I just changed it finally, it never worked because it probably was clogged up with marine growth. You sure that was the speedo wheel and not a transom mount transducer for a depth finder? I think mine came with a depth finder glued to the inside of the hull, but there was never one on the dashboard. Maybe the POs removed it. I had a 15 year old Humminbird that worked on an off (probably just needed a new transducer) but I replaced it with a Garmin 441s GPS/sounder. I was happy to note that when I remove d both the old transducer and the speedo pitot mount no water came out of the transom. |

My 99 LS has that paddle wheel for the speedometer. I have the gauge cluster that is the automotive style, all in one thing. It stopped working right after I got the boat. I bought a wheel and plugged it in, spun it and the speedo registered. Then, in a moment of shear laziness, I cut the wire and spliced it instead of pulling it through, I ruined it and it has never worked. I have a Garmin street pilot type GPS that I use for speed now. A lot more accurate anyway. I posted the link, but I didn't notice that they are out of stock. For the price they want, my opinion is to go the GPS route. |

I don't think it is a transducer for a depth finder because I have on the dash and it works. Mine may be like yours that has it glued inside the hull, not sure need to do a little more investigating tho. Pickled when you cut it and spliced it what wires were in the tube? I am asking cause this might make it easier to ID. |

I just got off the phone from the dealer, they contacted FourWinns and guess what they don't have anything like that in stock. So the search continues. The dealer suggested I change out the speedo to a pressure one. I think that a working speedo is not a big deal, as they hardly work good anyway. I always use my GPS on my phone anyway. By the way you guys on here ROCK. |

I am asking cause this might make it easier to ID. You're probably right then, I never tried to trace the wires on mine to see where they go. I think I'd just use a gps for speed. I tested the speedo and it worked when I blew some compressed air in the tube on the transom. Since I have both now I can see how close the speedo comes to the gps. I bet if you searched around on the net you find one of those paddle wheel senders. I bet West Marine could source one. |

The mid 1990s to early 2000s FW boats used Airmar paddle wheel transducers. It's likely the early 1990s ones did as well. The Airmar website site has a cross reference list where you can put in gauge manufacturers and search if there's a current Airmar transducer that's compatible. |

I think GPS is the way to go. I have tested it against my sreedo in the truck and the wife's minivan and seems to be pretty accurate. If I ever find the need for one on the dash I will probably get on but for now GPS will do fine. |
