Default Some numbers

Ended up repowering with a 2000 Johnson 150 Horse Looper and was surprised the numbers were only slightly better than the '84 Crossflow I had on it.


From what I remember about the '84, it would only do about 5100rpm with a 14x19ss prop, draw up to 22gph and do 43mph (1.95mpg).
The '00 will do the same (today way rough water and wind) rpm, with the same prop but draw a little over 18gph (2.32mpg).

(It would do 44mph at 5100rpm the other way down the river)
Here is the '00 at idle in neutral.

And at idle speed (3.38mpg).

About 3900rpm and 30mph (2.71mpg).

About 4200rpm and 37mph (2.63mpg).

Well, what do y'all think??
I'm gonna try a couple or few different props but have no complaint with what I've got so far.
