    Re: YAMATO COOLING UPDATE..........TIS THE SEASON.

    Hereís some photos of what Iím working with. The photoís angels are all a little off and my cutter that cuts the pieces is only accurate to .002, but you get the general idea.

    Iím excited to not use the new approved method but Iím even more excited that anyone can finally cool a water-cooled race boat engine.

    Iíll wait for the approved way to measure these inlet holes, as both methods Iíve used show potential issues.

      Do you know when the decision will be made on drilling 300ssH?

      from page 33 in the SO tech manual for the Y80:

      https://www.apba.org/sites/all/files...12-3-17%29.pdf

      2017
      o
      Water inlet enlargement and grooving rule for cooling added for all approved Yamato engines in this class.

      How will this rule update be applied to the Y80 with 2 holes, does that engine have reported cool issues at 1/2"?
      "Keep Move'n" life is catching up!

          Great news, now 300ss racers can race other classes with the same sealed engine! This is good for them and the other classes that will gain participants.
