First, welcome!

You may have an easy fix or you may need to replace your cluster. I would check and double check all of the connectors on the guages and all of your ground wires. If not the connections, if you have the VDO cluster, you may need to do a swap. Search VDO on this forum and enjoy all of the horror stories.

Good Luck and let us know what you find.

No VDO cluster on these oldies, they have reliable separate gauges, but the trim sender corrodes inside and then it does not work. If you can find the wires where they come into the engine harness (both are brown I think) through the transom, if you disconnect them at the terminals, and then hook up an ohmmeter while someone cycles the trim up and down, the reading should go from 0-200 ohms if the sender is good. If not then you have to replace it. It's mounted on the right side of the pivot housing, a plastic disc, with an arm coming off of it, 2 bolts hold it on. The OE ones are no longer available, but Sierra makes one that works fine.

thanks for your response ..i will check those things today....i will let you guys know what i find!

Take a look at this parts diagram, the sender is part # 86 http://www.dougrussell.com/partscatalog ... 09,507,508 Like I said, Sierra makes one, you can find it on iboats for less... The speedo, could be a gauge issue or the plastic hose that goes to the speed pick up on the transom may be disconnected.... As you can see I have the same boat right down to the engine, 4.3 4bbl Rochester Quadrajet, it's a good running boat and very stable handling.

your pitot tube may be stopped up on the speedo....it;s a hole in the small plastic arm that hangs just below the hull at the transem....newer model volvo drives have this built in to the lower unit....take a thin metal wire and insert into hole to make sure not plugged.....also, my money is on the sending unit or corroded connections on the tilt/trim meter.

The trim sensor wires sometimes break near the sensor, you may be able to splice them back together and seal them good if this is the case. The correct thing would be to replace the sensor, but just possibly giving a different option. This is what happed to mine and 1/2 hr. later it's fixed, and a year later it still functions correctly.
