Just bought my first boat (1994 220Z Talari 454 bravo III) and have a few questions. If you can point me to a previous post that would be great if not here they go.....1) Speedo does not work..researched the forums about it being clogged but was wondering if anyone had a picture where this would be 2) Throttle is very hard to move....the previous owner stated that the yolk needed to be greased...any suggestions? 3) Temperature gauge not working. I am a complete noobie to boating and like to research things before I go to a shop and get hoodwinked. Thanks in advance for any help.

Hi jasfiveo,

Here is a link for the Bravo III speedo pickup hole and connector tube to the transome: click here

Now for your throttle: You need to determine whether it's in the throttle controller or the throttle cable or linkage on the motor. if you can remove the controller, disconnect the cable and see if the controller is the problem. If it's smooth, then it's probably your cable or linkage on the motor. reconnect the cable and disconnect the other end from the linkage. if it's still seems relatively smooth, check the linkage assembly, other wise it's probibly the cable. See if it can be lubed, but most likely, it will need replacing.

Temp gauge: Check the wiring connections at the gauge, cable harness connectors and sender, corrosion from moisture and/or loosening from vibration are common causes of electrical issue on boats.. You may need to use a DVM to determine if the gauge has a good ground and power. The sender unit should be checked as well.

We have a growing library of manuals, brochures, wiring diagrams, and all sorts of information relevant to your Mariah, the stern drives and equipment. All of these are available to our contributing members. Click here to see what each level has to offer.

Good luck,
WetWilly
