    When friends ask to explain prop selection, I usually say that a prop pitch number is like a gear in a car with manual transmission. The lower the number - the more load you will take on plane and accelerate faster, but overrev the motor and only have that much speed. The higher the number - the faster you go, but the longer it takes to get there, also your motor might not have enough hp to spin it to desired rpm with bigger load weight. Just like a loaded car in a 5-th gear on a manual might not get up the hill, while cruising fine on the highway. The rest of the prop parameters, like diameter, blades, rake, cup and ventilation holes usually do not interest the average boat owner like at all. They usually ask either for a top speed, or what prop do I need to plane with that many friends and family onboard.

    Dude! as always, informational GOLD! I went from an aluminum 18 pitch/14.25 diameter to an aluminum 21-14.5 on my old I/O and way increased my fuel economy, and I mean by a good 25%, played with the twin Evinrudes, but I'm feeling pretty pretty good with the current set up with 19 pitch 14.25 as an all around prop, getting an average of about 1.9 to 2.2 MPG and still being able to hit 45 MPH when I trim up and mash the throttle seems a good compromise. I just don't see the value in changing out stainless props on motors that I intend to replace down the road, when the Props cost as much as they do and I need two. You can bet I will be doing some serious research when I repower, still not wasting money on Sharrow props,

    Hi there..your fellow mechanic from Sweden😎next topic on propellers would be the cavitation problem...explain to your customers how cavitation can ruin a very good expensive prop..also explain the difference between the Cleaver and most of the props that are not surface cutting props and when to use them..also I would like to see a video where you explain having multiple outboards on..talk about getting clean water to the prop and what kind of rotation you should use...inwards or outwards..that is extremely important on your setup for best perfomance..and not forget the more popular conversions nowadays are now getting a bracket 3 ft back and how that will affect the total setup...looking forward to the next episode..best regards from Sweden

    Excellent. I knew I had an issue with my 2003 Key West 22cc. I repowered with a 2023 Mercury 200. Top RPM barely hit 4900 with a top speed of 28MPH (barely). The dealer put a 15" x 15" stainless steel prop on it. With the tools described, its pointing me to a 13.6" Diameter x 21" pitch. Holy cow that's different. Going to do some testing. Marina mechanic said I should hit 42-45 MPH with this Mercury 200. We'll see! \

    I remember when GPS came out changing everything. With a fuel transducer you could dial it in for efficiency at idle or wot using the trim and jackplate. I started saving a lot of fuel but one of the best mods was having Bob's modify the lower unit with a nose cone and low water pickup. Elongating the lower unit moves the area of clean water further back so the prop is running in cleaner water.. With a 22' CC and 250 I went from 56 to 63 mph and 15-20 % less fuel. It seemed more planted with less cavitation turning. too. I tried a lot of props and was really suprised how different props in the same size/pitch from different manufacturers can feel so different. I know a lot of places let you test drive props for a day or two for free so imo worth it to try a few.

    Years ago I had a conversation with a "prop expert" at a boat show so I asked him to recommend a prop. He asked about the boat, 23' cuddy, 5000 lbs, with a 240hp Cobra I/O. He said "with this prop you'll hit 40-45MPH and about 3 MPG at cruise." I asked him what it would take to get closer to 50MPH and over 4MPG, his answer was "a different boat." I showed him photos of my chart plotter showing full speed at 48 and cruise at over 4MPG, that shut him up.

  • @davidjessee7701

    Being a marine mechanic and a boater , the most common mistake I see from boaters is the lack of trim they apply to get the bow up (less wetted surface) and to get the optimal RPMS .. When it comes to Bass tournament fisherman, cost is always backseat from a hole shot!! A fisherman will sacrifice a little top end speed to get that boat in front of the pack.. so going to a 25” pitch prop versus a 27” pitch prop mabe the play.

    I just put a 140 hp Siemens electric motor in a 27" tri hull fiberglass work boat. I use the boat for dock construction in Montana. Any thoughts on prop selection with the different powerband of an electric motor? I often load the boat with a bunk of lumber and lots of tools maybe 6-8 thousand pounds. The old Mercruiser 165 straight six did a decent job of planing up and going a couple of miles to work, but the Montana temperatures killed it a few times.

    I've been pretty happy with the 13x19k Yamaha OEM prop on my 130 Saltwater series half cab. Boat will reach 73km/h (perhaps a smidge more with trimming it up more) and sits at around 5700rpm.
    I'm sure if I fiddled around I could get a better prop for hole-shot or top speed, sacrificing one or the other. I do like both the current acceleration and top speed, so I'm unwilling to really sacrifice either unless I could find a prop that gives gains in both.

    • @chevyon37s
      @chevyon37s 5 місяців тому

      You can’t be serious…
      different lower units have different gear ratios which is going to have a major play in what prop works best for your setup. Nearly impossible to suggest anything that would be a worthwhile upgrade for you based on the parameters you’ve given. Hell you didn’t say what prop you’re running now and what performance aspects you’re seeing out of it.
      So I recommend you talk to your boat shop and see what they say. Or really get some performance stats of your current prop and see what you’d like to change about it. and then start shopping for new props from there based on what you want to change. Some of it is trial and error.

I have managed to service or repair a lot of components on the motor that have saved me lots of cash and given me experience and time on the water. Thank you. That said my tachometer has never worked and the one that was on the boat when I bought it actually caught fire so I replaced but have never got readings that made sense. Do you have a video I can reference to try and figure out the problem with my tach. My tach jump around like crazy when I start the motor. Once I get going it either reads 0 or on occasion it will read between 1000-2000 regardless where the throttle is. Any help would be appreciated.

    You guys should try ceramic coating the non gripping surfaces of the prop. This would be most efficient, The gripping surfaces, open faces rear of the boat, they should be scuffed probably with a fine 3m pad, not polished, because the props supposedly grip. I think they would work better scuffed, because how would something super slippery propel itself through water, but like fish, it could be slippery yet, they shove large volumes of water around, with least effort.
    So maybe a fully ceramic coated prop would help.
    I will test it myself, I know the hull benefits 5 or so percent or more with having less water resistance.
