Fuel burn with single 9.5 hp
 

Got a mint mid 70's Evinrude 9.5 hp outboard that runs great, less than 50 hours on it.

Thinking I'd cut the fuel burn vs my 150hp so I can reach the deep for bigger fish.

Real pretty motor, shiny blue will accent the boat trim.

Question is......... what about the top speed ?

Some of you guys know about my V that ran 100 mph - off a cliff but I don't fish that way every day.

From what I remember those things burn just a little more than a gallon an hour.
On the V you'd probably get 2-3mph.
You gonna have to do the math being you know how far you are going in order to see how many days in advance you need to leave to get there and back.

I have a 72 9.9 evenrude on mine .2 to 3mph tops it'll burn about a gallon a hour at that speed.at trolling seep it's maybe 1/2 gallon.

Joking around a bit....... thought it clear but now you know. Happy Holidays.

What about the speed with other size kickers? Lets say a 9.9, 15, 20, & 25hp kicker. I would like to have a kicker on my V and am considering a 25.

I'm running a Yamaha 15 and get about 7mph, and burn about 1.5 gph wide open. The hull speed of a V20 is approx 7 mph, so that's all you'll get with 15,20, or 25 hp. The only advantage to the higher horsepower is if you're running against a current or heavy wind.

higher hp will help in a head wind and in waves but not against a current.... 7mph top speed against a 7mph current = 0mph

Right you are. Thanks for the correction.
