Hello there,  I took my 1976 V20 out and had it winterized.  My prop is pretty beat I was wondering ifs its worth it to try and get it redone or just buy a new one.  I am not sure what size or pitch prop to get the engine is a 199? Merc 112sp.  I tried reading it off the prop but dont seem to be able to read it.  Any help is greatly appreciated
Thanks

look at the last 2 numbers, they should be followed by a letter P. that indicates picth, that should be your starting point

The prop is where "the rubber meets the road" for a boat...if it's not right yer wastin' gas and losing performance...you should be in the neighborhood of 15" dia. x 17 pitch (15 x 17) although you'll want to experiment for best on your particular boat...do you have a working tachometer on your boat and know what the engine manufacturer's highest recommended RPM is?...

Nice chart but what does a V20 step lift weigh on average. I would like to know if I have the correct prop on mine.

Dry weight is 1900+ with a 500 # motor, and 60 gal gas 400# I say you safe at about 3000 pounds + gear and such, and people all of 4000+  I hope that helps some

I think MJ has hit pretty close. Check here in the albums in the history section. Doesn't go back to '76 but you'll get pretty close with this info.
