That explains it. You didn't get the HO's.

If you send your props in for lab finishing to a shop like Bblades, you can get those RPMs more in the middle of the suggested range. Running at low RPMs is actually more stressful to your drivetrain. I like to set my props up to be just below the rev limiter in cool 50° to 60° weather. The 31 also needs a little more cupping to help carry the bow.

thanks for the input...

I'd like to know how you guys are getting low to mid 80's with 500efi's ?? I'm guessing at sea level in good chop?? I have 580hp 502's running stock 28's @4900 and labbed Bblade 28's @5300 both at 77 to 78 mph. Mid summer very HOT and Humid @ 500 ft about sea level very mild chop. I hit 81 in the cold air in the spring but never over 78 again even in 2 to 3 ft chop at the lake.

I'm thinking labbed 30's or nose cones to get more bit out of the labbed 28's? Any thoughts??

You may want to try a 30 pitch prop. My 31 came from sonic with a 30 props on it. that boat would do 81 any day of the week.

Ok thanks I will try a set of 30's in the spring. What rpm's were you turning with them?

Let's do the calculation....

It was COLD... You put your fat head down behind the windsreen to keep warm...

boom... extra 3mph!!!

Try that when it's warm and see what you get!!!

How many days to summer? This winter is killing me!!

Enjoy Florida Buddy!

Actually it would only turn about 5100 and change, it would depend on the weather. I think having the A/C, eletric head, microwave, and my wife packing it like a hotel room didn't help. Still a great boat we both miss it.

You ran with me on a nice summer day...You know what they will do...You going to come back to the swamp next year?? :drink:

You can count us in for the Swamp Run for sure. With more boats next year. I'm pretty sure the Pa Posse will there.

Brian , just made reservations in Key West for a night. can't wait for the warm weather. Going to try and see the new 38 while we are down there.
