That boat looks real clean in NJ.
Compression for the Yamaha 130's will usually test out b/w 135 - 140 psi in each cylinder.
Remember to run the engine first to get it warmed up.

Also on those early Yamaha's (pre-1993) outboards
Shift Shaft - There is a small gap b/w the mid section housing and lower unit. The shift shaft runs down the middle. The shaft rotates to shift the motor in and out of gear. If it's rusty then it probably hasn't ever been replaced (they last about 15years) . It's a real PITA to replace them (have to pull the powerhead). Make sure the boat shift cleanly and if the shaft hasn't been replaced - use it a negotiating point b/c that repair will be expensive.
Steering Arm - These get really rusty and rot off if the motor was neglected.
