Single-Engine Outboard World Speed Records (Draft)

Here is our first draft of history on the Single-Engine Outboard World Speed Records. We are not able to locate a comprehensive list from the UIM or APBA so we are looking for input.


Please leave any corrections and new comments. We will update the article as new information gathered and validated.


1958 – Arthur D. Talmadge

  • Record: 121 mph (194 km/h)

  • Location: Lake Havasu, Arizona

  • Boat: Mercury-powered hydroplane

  • Details: Talmadge set a notable speed record for an outboard motorboat, achieving this speed using a Mercury engine. This benchmark was a significant achievement in the 1950s and helped establish Mercury as a leader in outboard technology.


March 16, 1966 – Bob Walin

  • Record: 130.929 mph

  • Location: Lake Havasu, Arizona

  • Boat: 17-foot hydroplane (Starflite IV) powered by an Evinrude 100-S V4

  • Details: Walin set a significant outboard speed record using an Evinrude V4 engine. His achievement remained a benchmark for the era.


August 8, 1973 – Jim Merten

  • Record: 136.381 mph

  • Location: Fox River, near Kaukauna, Wisconsin

  • Boat: Twister-Craft three-point hydroplane powered by a Mercury Twister II engine

  • Details: Merten broke the previous record by over 5 mph, and this record was recognized by both UIM and APBA. Mercury's Twister II engine was heavily modified for competitive use.


September 1974 – Bob Walin

  • Attempt: Estimated 150 mph (Record not officially achieved)

  • Location: Lake Havasu, Arizona

  • Boat: Entrop-designed hydroplane powered by an Evinrude V4

  • Details: Walin attempted to retake the record but tragically crashed during his run. His death followed months after the crash from injuries sustained.


1982 – Bob Spalding

  • Record: 139.66 mph

  • Location: Lake Windermere, UK

  • Boat: Powered by a Johnson V8 prototype

April 1983 – John Sherlock

  • Record: 135.804 mph

  • Location: Moore Haven, Florida

  • Boat: Modified Mercury 2.4L V6 by Dick O'Dea Racing

  • Details: Sherlock set the APBA and UIM MOD U World Kilo Record, establishing the fastest outboard in the USA at the time. Though it fell short of Spalding’s V8 record, it was an impressive feat for a V6-powered boat.

Was in Seattle this last Friday, picking up parts from Seaway Marine. Greg Jacobson, owner of Seaway, and a long time OPC/STOCKracer (49 ci, 3 cylinder) OMC engines gave me the big tour. He showed me that 1989 Karelson hull that is being restored ( J believe its finished) as well as a few other racing hulls. I could be mistaken, but Im almost certin that was the same hull and engine as you have listen as world record holder , 176 mph .
