All, I am new to boating and I came across a 1973 Century Trident I/O with . The boat itself appears to be in good shape. Tomorrow I am going to meet the seller and check the floor for soft spots and any damage to the fiberglass itself. My question is that the seller says its needs to the motor re-sealed, a new Gimbal Bearing, and a new throttle cabling. Can anyone give me an estimate on what this is going to run me at a shop??? Is it something I can do myself? Keep in mind I am new to boating. I chose this boat for the simple fact that it fit my budget and will hopefully be a good starter boat for my family and I. I have a 5 and 3 year old, so I figured the wife and I could fit in the boat and fish just fine. Any information anyone can tell me about this about would be incredibly helpful!!! Thank you in advance!
