Prop pitch and fuel economy?

Recommended Posts

When running a 25" pitch prop as compared to a 23" prop I am getting about 3 - 4 MPH more speed at 4000 RPM's. I assume this means I am getting better fuel mileage with the 25" prop. Is this correct? This also means I am only running 5400 RPM's at top speed with two guys and gear. The rpm range for my motor is 5000 - 6000 RPM's. Is that lugging the motor to much. Most of the time I am criusing around at the 4000 RPM"s range.

I would think the extra load on the engine means your burning more fuel especially coming out of the whole getting up on plain.

Remember Aa truck with taller gears in the rear end may get better gas mileage but it has a transmision to get you at optimal opperating speeds.

I would go back to the 23" prop to get your RPM's back up where they should be. I agree with croixflats that you're probably burning more fuel because you're lugging the engine pretty good.

If you get a good load of people / gear you're going to have a lot slower holeshot and will burn more fuel there too.

    • How deep were the trout running?  We heard ultra deep on Crow to 30 ft.  The 30 ft number came from people actually catching them.   Thanks for the pics!  I like the fly rod smallie.
    • try the raid spray on grass at bottom. 
    • Here are some pictures from this years trip!
    • How do you keep ants off your feeders, especially hummingbird and oriole feeders? I've tried Toro and Raid sprays on the post but it seeks the birds don't like that smell either and i don't see many for a while. Has anyone else experienced that? Any good ideas?
    • I should’ve looked closer - I have an eyes open pic too. 😌  Tough to tell sometimes on my phone screen.  
    • Among other wilds that have moved into our urban areas, we can now add loons.  There is a breeding pair on the lake formerly known as Calhoun, mostly staying on the west and northwest sides.  But there is also a bunch of yearlings fishing the east side, numbering maybe six or seven and so unafraid that they come right up to the 36th Street dock and try to steal suckers being used for musky bait.  Maybe the call of the wild is not really so alien to the South side of Minneapolis, but it looks like the loons have moved in and can be heard calling from time to time. 
    • Sounds like you guys gave her heck up there to find them. I'd be praying thanks, too if I got that one on! ☺️
    • Quick recap:   Weather was too darn “nice”!  Upper 80’s - 90’s; no wind to speak of; mostly sunny. Water temps were anywhere from 64 - 71 depending on location and day.   We looked the lake over from end to end, marking up our map and returning to some places where we saw fish either later the same day or a couple days later.  We could literally see the transition from spawn to post spawn happening during our stay.  Being new to both muskie fishing and that lake, we spent time in dead water as much as good water but feel like we got a pretty good handle on how to go about setting up a more efficient return visit.  It was a lot work and long hours but I’d go back this weekend if I could so I must’ve enjoyed it.   A few pics as hoped for:
    • big dave 2 and leech, darn good lookin meals!!!!  Dave have a good weekend!!!!
    • Ok Dave have a good weekend. Hope you get over the whole butt hurt Leech deal! Not sure where you got that I don't like folks smoking or grilling things?  I know I do enough. Have fun! 🙂
