My MaxProp is an older 3-bladed model—perhaps the “Classic”—which requires assembling a lot of loose parts on the shaft, as Minne describes. You would have to deal with this if you wanted to change the pitch. PYI does not recommend doing this in the water! (We had to reassemble our MaxProp in the water once and it took my son 90 minutes on SCUBA in shallow water that allowed him to plant his feet on the bottom. It was either that or get towed to a marina for a haul-out.)I sent my max prop to PYI to repair a ding in the leading edge of one blade. It came back looking new, but I still needed to assemble it and set the pitch correctly. They have a few different models. Mine requires lining up letters on the gear teeth inside the hub and it installs in pieces.
This is not so. I have done many, many underwater installations and repitches of the Classic model and almost every one of those jobs has come from a PYI referral.PYI does not recommend doing this in the water!
This prop is the now-discontinued Eco-wind model (I mistakenly identified it as an Easy model in the video.) It does have an external pitch adjustment feature. However, PYI has recommend that the prop be shipped to them for reassembly as they believe it was done incorrectly at the yard. That said, no Max Prop, regardless of model, requires hauling the boat for repitching.However, IIRC, the newer MaxProps allow for an easier adjustment in the water. I can’t tell for sure, but it looks like the prop in the video is a newer model that has a much simpler adjustment process that still needs a diver, but does not require a haul-out.
I stand partially corrected. When I had a prop casualty about 18 yrs or so ago, my son disentangled a concrete block that had been winched up, ripping and dog-earring all 3 blades. In the process, he dismantled the prop and placed the parts on the dock. That’s when I called PYI for help.This is not so. I have done many, many underwater installations and repitches of the Classic model and almost every one of those jobs has come from a PYI referral.
Exactly. You can check out the instructional videos on the PYI site and see for yourself how complex the installation of a Classic model on the shaft is, compared—for example—to the Easy model. Anyone who thinks installing or even repitching the Classic model in the water (which requires partial disassembly) isn’t a nightmare hasn’t done it or looked at the 3-blade installation video: https://www.pyiinc.com/max-prop-classic.html.The newer Max Prop models do not require in-water assembly/disassembly for installation or repitching.
