Engine Manufacturer Report

[mike ross]

I thought before we go to Seatle it might be nice to here how our engine supply looks going forward. Yamato - Rick Montoya, Tahatsu - Bass Machines, Mercury - Wheeler Marine & Dave Scott, Sidewinder - Sled or Ron. Knowing what the available numbers look like will help the SORC make some real sound decisions on the future of Stock Outboarding. If anyone involved in any of the engine manufacturing has info as I may have missed on who should report feel free to chime in. I know folks like George Stillwell have put together engines for our new members from new and used parts. Another one is Gary Pond he has like new equipment in just about every class. This also will let Santa Claus know who to bring a new motor for under the christmas tree. Mikey

Sidewinder 20

Over the years, I guess I have become a motor snob. I am into PRO racing and realy enjoy high tech engines from around the world. I enjoy watching good hard racing in the Stock classes at the local races, but the motors do nothing for me.

I had the chance to watch Worm test the new 20 Sidewinder at Lock Haven and was impressed. At Kingston, Mikey and I were out in the patrol boat in the first turn in 25ssr. Worm ran a small roll up boat against the bigger restricted Yamatos and just put a hurting on them. The motor ran flawlessly.

I am impressed. Ron and Ed, you guys should be proud of these motors. Ya done good.
