Re: 500 EFI Power Increase
No, just finishing & cleaning stupid stuff still from AC install. I have a small water leak on the back of the dyno'd engine I can not find. One day its there, the next time, nothing, the next time 1-2 inched in the bilge. It shows up on the back of the top of the notch in the transom. It only show on high RPM runs. I guess I am going to have to take off the hatch and make a run.
Last weekend I made a long run Sunday.
The 32 Pitch labbed w .020 extra cup ran 50GPS@3200RPM, 80GPS@4600RPM, 85GPS@4800RPM. Weather sucks today. Looks like tomorrow will be better.
GPS recall shows 94 so far. That was with the 30P @5700RPM. I think this prop will get 95-97.

Re: 500 EFI Power Increase
Memorial day Sunday I did a 110 mile trip. I filled the boat before I left. Yesterday I filled the tank again & I used 70 gallons. That equals a 1.571 miles per gallon. With the 500EFI's stock I got 1.33. That is right at 1/4 extra mile per gallon. That was the ultimate benefit for sending the engine to Mark @ Precision to Dyno.
Gas is $2.15/ Gallon
110/1.33= 82.7 Gallons x 2.15=$177.80
110/1.571=70.01 x 2.15= $150.52
Savings $27.28 that day.
Lets assume I do not run that much. I assume I only run 75 miles per day average.
75/ 1.33 = $56.39
75/1.571= $47.74
$56.39- $ 47.74= $8.65/ Day
March 6 Days - Spring Break
April 4 Days
May 6 days
June 8 Days
July 12 Days
August 10 Days
September 8 Days
October 4 Days
Total Days 58 Days
58 x $8.65 = $501.70
That means it takes 3 years to pay for the investment of Dyno. I do many poker runs and weekend trips not accounted. I feel like the dyno calibration was really a 2 year return.
Not a bad return as well as good speed increase

Your starting to scare me with all this justification stuff. The upper 90's top end was more than enough justification

Re: 500 EFI Power Increase
Russ,
I feel even better now. I can't believe I messed up on the math. Oh well, good thought but did not check everything on that post.
Indiana, Magic,
I do not show my wife any of this stuff because I would get the same answer. Matter of fact, she still thinks the motors are stock.
