Will these mods work/help? Please Advise
Just bought the Riva Rear Air Kit...this will work with the Riva thru hull exhaust right?
It has been determined that I am over propped...especially in South MS extreme heat/humidity... doing 68 gps at 7650 rpms...2005 rxp stage 1 with thru hull...
Will the addition of the RR I/C and the Riva Rear Air Kit plus flow rites...cool things off enough to get 250-300 rpms and a couple mph...

Yes, it works perfectly with the thru hull exhaust.
The intercooler will add lots of RPM's. Don't pitch your prop again until you install all your mods and see where you stand.

I think your prediction is about dead on. Add a "green" SC impeller, fill the ride plate holes and you'll be 72+ @ 8100 rpm

I was hoping you would 'advise' Jerry...thanks for the input!
What is typical rpm loss for high heat/high humidity? What are you guys seeing out there in these hottest days of summer?
Water temps in upper 80's, air temp 95 plus, and high humidity?

When I upgrade S/C...it will be Riva S3 with 42's...and ride plate has been filled...but needs some minor patching where epoxy has come out...thanks
