Ok, not sure what to do and whether this is a problem with the motor or boat. Anyway, my gauge is showing like 5500 rpm with the motor off. It doesn't move with the motor running either. Is this a gauge problem or do you think the motor may have a problem? My dealer has one for like $90.00 but don't want to buy it unless i know it will fix my problem. What should i do?

check the wires @ the tach make sure you have a good ground and a switched hot before you buy a tach, regaurdless of engine problems tach needle should move to zero when power is on... good luck
