Well my neighbor gave me a 13 x 19 that I thought was too much prop so I called our local prop shop. And he said given the light weight of the whaler and a 50 hp I should be more than fine with that prop. Being that is what he does for a living I will give it a shot, doesnt mean it will work but we will see. As far a "hook" in the hull i dont see it after spending a couple hours sanding and painting and i had a 1978 with no "hook" either. let me know what you think. Thanks

Prop sounds right.

The early 13 Whalers were designed with a hooked hull for greater stability in high speed turns.
If you put a 10' or 12' straight edge against the kelson, with one end right at the transom, the ends generally touch, with about 1/2" gap between the straight edge and the hull about 7'-8' forward of the transom. At top speeds, the angle of thrust can easily overcome that hook, but with neutral trim, 75% of the whole hull length will run wet, rather than just the last 3'-5' you can get with positive trim. At neutral trim, no matter how much power you have, the 13' Whaler will never chine walk; indeed, it cannot.
