PerfectPitch prop from CDI
Anybody have experience with these? I am about to replace my fixed 3
bladed prop on my 8.5M S2. This looks like a potentially good candidate replacement because they have already figured out which prop works for a given boat and because they say they can put a larger prop on with their "Extendo" system. I am a little worried about the plastic of this prop not being able to take my aggressive barnacle removal method. Is it easy enough to remove that re-painting it every so-often works? My old bronze prop has succumbed to corrosion and many impacts with oyster beds and with a Laser mast in the water. Now, one of the advantages of a 2 blade prop is that you can align it with the keel for lower drag. How does one do this? Do you simply mark the prop shaft inside the boat and then rotate it till your mark is in the right place? This really seems like a PITA considering the gawdawful engine installation on most boats. Even on my boat it requires removing an engine panel and peering down into a dark space. Is there any other system? Would the prop left in neutral auto-rotate to the lowest drag position (I have never had a two blade prop so I dont know) and stay? Could I attach a magnet to the shaft so that it engages a magnetic reed switch (non-contact) to tell me when it is in correct position? Can you get it in correct position by "bumping" the start switch? |
