MRP Bud Light Tunnel RC Boat with Graupner GTX 650 Outboard

This is a Model Racing Products (MRP) Bud Light Tunnel boat from the late 1980s. It originally had an MRP outboard on it, which I have, but parts are hard to get for them, so I decided to run a similar, but newer and readily available motor in its place. The Graupner GTX 650 runs a Speed 600 Race motor. Prop is standard 31mm. Running 7.2V NiMh battery through a Traxxas Nautica ESC.
