older 50hp vs. newer 40hp

[newbie600rr]

I would like to know what your guys opinion is on an old 50hp vs a newer 40hp. I currently have a 1982 50hp johnson w/o tilt/trim. It is on a 16ft aluminum blue fin that is very similar to starcrafts. The 50 pushes the boat at about 33mph but takes a little while to get up on plane. I came across a 1999 40hp johnson with tilt/trim for a really good price. What differance in performance can I expect if I was to switch to the 40hp. I don't want to loose to much because the older 50 is about the min that I want.

Personally, I like old things but, you are talking about 17 years difference though. The newer forty is a gutsy motor but I'd stay with the fifty.

The newer motor is prop shaft rated for HP, the older one crank shaft rated. The 50 is somewhere around 46 HP on a prop shaft basis, the 40 is likely actually somewhat over 40. Bottom line, not too much difference.
