This is my second boat, but the first I/O. 17 1/2' Sea Arrow 1986? I think. Anyway the motor is not currently in it. (Block cracked on old motor, different motor from truck Chevy 305.) The coupling is brand new. Is there anything I can, or should, check before I put the motor in. Not just the motor, anything, drive, cables, wiring, whatever. If the motor and drive check out OK after running I will be back with many other questions. Already read some interesting stuff on covering the seats. Great Forum.
