My max speed is 5 knots at 2500 ROM, 5.5 knots at 2800RPM.
First of all this seems slow. The boat 1995 came equipped with a maxprop. Trying to confirm pitch settings.
MaxProp manual requires gear reduction value to provide correct pitch. The 3GM30 manual has three reduction ratio’s listed (2.0/2.61/3.20)
A - Am I correct that speed should be higher
B- If so can someone advise on pitch
TY
Contact PYI. I’ve found them very helpful. https://store.pyiinc.com/pages/contact-pyi-inc
I just had my maxi prop taken off - for installation of a new pss pro shaft seal - and reinstalled - the blades were placed on the “K” setting , if that helps. The Freedom 35 is a big heavy boat but it should scoot at that setting, provided calm seas and clean hulls and blades. Hope that helps.
For what it’s worth, I do 6.2 kts over water in an F30 at 2800 8 month old bottom. I have calibrated against GPS and this is pretty close to reality. Boat weight 7400, probably 8400 +/- loaded out, but no beer and me on a diet.
Here are my setting data -
GEAR RATIO 2.42-1
PROP DIAMETER 17"
PROP ANODES 63 mm
suggested settings 16˚
letter codes C K
Make sure you have the same gear ratio. If not, contact PYI. They will be happy to help.
