For purposes of discussion, 1986 54 MY with 8v92TA's. Assume I am an idiot and mechanically unskilled.

Port tachs stopped working at both helm stations. Glendenning quit engaging at same time. I am guessing failure at sender.

Where is the sender and what should I look for?

What type of tech do I call to fix? Detroit Diesel? Glenndenning? Other? Boat is in Tampa.

Would installing Flo Scans, digital tachs, or an upgrade by necessity fix the problem?

What is the estimated purchase and install cost for this route?

Thank you for your thoughts and assistance.
