CMB 45 HR vs. CMB 45 RS

[SeanKewley]

What are the advantages/disadvantages between the two? I need a motor for my Whiplash sport 40 and was planning on purchasing a CMB 45 HR for it. Should I consider the RS?

Hr is more user friendly rs makes a little more power but is a pain to work on.... Hrs in sport 40s here are running well small prop and lotsa rpm is the key

you could run a big prop i.e a 1455/3 with the HR motor you just need to lengthen the pipe to about 10 3/4.

I was planning to run an Octura x450 slightly de-cupped.
