Solas 15/19R or 15/20R help needed
With these mods which prop would you choose and why.
Riva 4 in air
intake screen ditched
Supertech valve springs and retainers
Gen III and pipes
ET 137 not sure on +3 or 4
VTECH custom tune
VT 1100cc injectors
VTECH data logger
I would like a good combo of acceleration and top speed.
Thanks in advance.......

So my 15/19R was stamped 15/20. Solas only makes the R series for Riva from what I understand. Not sure how special they are but they go with their kits....probably for predictability of results. The solas guide shows SRC-CD-15/21A for stock and limited engine and SRZ-CD-16/21A for Modified engine.... not sure what all that means.

Get the 15/20-22 to get the better root angle then bend to your needs.

It doesn't matter which one you buy as you will still need to re-pitch it to fit your mods, and it is the last item in the bucket list!

I would go with the SRZ 15/20R and definitely go with the ET + 4

If you want that rpm range with a 137+4 I would go with the 15/21 for summer and then 15/22 for winter, the 15/20 will be close to 9000rpm

I've run 15/20 and 15/22.... The 22 allows more room to pitch and worked better for my ski but I need to send my prop out and get it completly pitchs.. Now I'm like a 15/25 with a 68-140 at 8600
