Help Determining Prop Pitch

[dachyk22]

i have a 3 blade stainless steel prop on my 1973 merc 850 there are no stampings or numbers anywhere on it, is there a way to determine the pitch using say a protractor or tape measure just curious what i have

Re: Help Determining Prop Pitch

Did you actually remove the prop and look at the hub. Sometimes the numbers are hidden behind the prop washer and nut. No - you can't measure prop pitch accurately. A prop shop uses a pitch block to check pitch.

An old , Mich wheel?, prop we have on my '69 Merc 800 that only has the 19P stamp on the hub between two of the blades. If your prop was painted often enough that stamp might be missing.

Out of curosity why is knowing the prop specs important to you? Is your motor performing the way you would like it to?
