My recently bought 99 Larson LXi 186 has a trim gauge that does not
move at all but is stuck fully up. The trim controls seem to work just
fine but as a new boater I would like to be able to use the gauge.

Any ideas on what I should be looking for to make the gauge work?

Any ideas on how to fix would be much appreciated!

Also my speedo only works at higher speeds, needle just sits there
until the speed is over 20 mph.
