Temperature and Altitude

[Richard Hartley]

Yesterday in Tucson it was 102F the elevation at the pond is 2250Ft
I was able to get my B Mono to run just fine but was unable to get my A Hydro or my B Hydro to even stay on step
Tried richer leaner and smaller prop on both but to no avail.
Would like to hear from you about what you might have done
I was running 50% nitro and thought that back in the day I ran 25% and even on the hottest day could get the boats to perform.
Advice welcome
Richard

Lengthen you’re pipe a 1/2” to start as well as a smaller prop. You may need to work with head space as well, I’ll go through my notes when I get home.
Thanks John

John is spot on. I always lengthened the pipe for Tucson and Las Vegas.
