I have taken my motor to a dealer to get a quote on new lower unit. The quote total was $7561.00 out the door is this normal? It is a TM so I understand it is expensive. If so I could use some advise on if its worth putting that much money into a lower unit on a 2009 with around 650 hrs.? Insurance has sent the money to do it so that helps but still not sure it makes since. O the serial number is 1B747858. Thanks
