    Inspecting 2002 Tracker 125 HP Outboard

    Make sure you test drive it. All the 4 cylinder mercury 2+2 topped out at 5250 rpms and not all had tev limiter. Trying to rev one of those to 6000 Rpm is a good way for inside bits to become outside bits.

    1996 mariner 30 hot start issues -- at my wit's end

    It's a carbed motor, perfectly normal to have to give it throttle after 5-15 minutes of sitting. If you don't want to give it throttle buy an EFI motor.

    Prop barrel slightly smaller than the gearcase

    You are probably going to cavitate the snot out of that prop. Exhaust is supposed to go through the prop not out around the blades.
