changed prop's last week and finally had a chance to run it today.
went from a 15 1/2 x 17 salwater series II to a 14 7/8 x 17 enertia.
today was not an ideal test day as sea's where 2-4's with 15-20 mph wind,
but here are my reults.with yamaha prop at 4700 rpm's i was running 30 mph burning 16 gph.i never could get much better than 1.8 mpg with the yamaha prop.getting on plan was a bit harder as the prop was a little big.wot with the yamaha prop was 39 mph burnig over 20 gph at 5500rpm.[my gauge only goes to 20]
with the enertia here how it was.full tank of fuel 175 gal's.3 guy's loaded to the gill enough gear to troll and bottom fish.4700 rpm was 28 mph [lost 2 mph]but fuel burn was 13 gph better than 2 mpg.i seem to be able to get 2 -2.1 mpg at several different speed's where with the other prop i never seen that.wot was 6000 at 38 and i expect it to get a little better with a lighter fuel load.even at wot i still was burning less than the 20 gal per hour and was still aroumd 1.8 mpg.the enertia also get's on plane alot faster.this is probably due to the 14 7/8 size.but it does jump right up on plane and that is pretty important where i fish as the water is so shallow.i'm gonna run it agian saturday maybe it will be a little better.
anyway 4 gags,3 red's and a bucket of blackfish.

Earlier this year, I went from 14 x 19 SS Yamaha wheels to 15.25 x 19 Mirage Plus wheels, and I raised the engines 2 notches. It's like and entirely different boat now. Better cruise economy, higher top speed, better low speed handling, quicker to jump on plane, holds plane at lower speed, etc.
