I have several boat issues I hope this forum can help with....
Engine is a Mercruiser 4.3 V6 (1995), with Alpha Outdrive.

1. Engine appears to have to slight vibration at slow speed (5-8MPH)
Above this speed vibration disappears. Could this be a propeller problem?

2. Tilt gauge on dash, does not register when in use. Tilt works OK, gauge
doesn't. register tilt in any direction. Is this possible related to a switch,
and not sending signal to gauge.

3. Speedometer gauge doesn't register? I don't have he old sensor type
at bottom of boat at stern. How is this speedometer gauge being
controlled ? Does the engine have a sensor, which may be sending a
signal to the gauge converting RPM's to MPH ?
