What Prop for me??

[57Cadilac]

I finally have my 1957 35hp Lark purring like a kitten. It is mounted on a 1957 16ft Cadillac aluminum boat. Scale puts the boats weight at about 480lbs with the battery in it and motor mounted. What pitch prop should I run on this setup for some speed and what kind of speed have people seen?
Thanks in advance.

Re: What Prop for me??

Standard prop was 10 3/8 X 13 1/4. It should work for your setup.
In 57 the motor was rated for up to 33 mph. Your setup probably about 25.
Let us know how you make out.We may be able to perk it up a little.
