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.

I would call Glendenning. They are very helpful and got mine going right off the bat. Sounds like you are on the right track for a sensor based on this link.

Not a great picture, but here's your sender.

There are, as I recall, two very small gauge leads attached. They are delicate. May be a good starting point.Semper Siesta

I thought glendenning uses mechanical drive cables between the engines and the unit. Senders would be far too inaccurate to get an exact match of RPM. A single problem may still be causing both symptoms, but it wouldn't be the sender.
