The Best Way to Measure Prop to Pad | How to measure Outboard Motor Height
Спорт
I show you how to consistently measure your prop to pad height. This distance is very important to the performance of you boat. If your outboard motor height is too low, it will slow you down. This measurement is very important if you are mounting an outboard motor or adjusting your manual or hydraulic jack plate.

A little about me:
I am James McBurnett. I live in the great state of Texas. Probably not where you would think, but I am located in the panhandle region. I moved here from Alabama and work as a Chemical Engineer in the area. After being here for a few years, I decided to get back to my roots as a fisherman. It is quite challenging in my area to find a body of water to fish. The closest lake to me is about 40 miles away.
After a couple more years, I realized how much I love fishing and wanted to share it with the world. Clearwater fishing was born. I wanted to teach people all about fishing. This includes rods, reels, fishing line, bait, lures, largemouth bass, crappie, walleye, catfish, bluegill, boats, boat trailers, outboards, and anything else related to fishing.
I also wanted to share my fishing experiences as well. To be entertaining, knowledgeable, comical, and FUN. This channel was created out of the love of the sport of fishing, and I plan to keep making content that represents that. Thank you for watching this video and reading a bit about me. Give me a shout out in the comments below and let me know you read this. Now get out there and go catch you some fish.

Thanks! It probably needs some decorations rather than just a white wall.
I was just at the Boat shop today about overheating and proper motor depth. The old man told me that for 1, a jack plate on my particular boat is not possible without overheating. The water intake comes out of the water instantly on WOT. It takes less than 1 minute for the alarm to go off. So, I have to remove the jackplate and bolt the motor straight to the transom. The keel is supposed to be even with but no more than 1 inch below the anti-ventilation plate. In other words, the entire prop is to be below the keel.
Question 1) How would you get the driveway or shop floor level for proper measurement? 2) Does the jackplate have to be level? I dont know if its possible to have a level jackplate, but it was mentioned to me. 3) The steering cylinder fir the motor hits the transom if I lower it anymore. Is there a solution for this if my motor has to come down? Only have about 1 to 2 inches left. I have to double check my measurements. I have been B**Tching about not getting on pad for years. 24 pitch 4 blade prop evinrude 200hp
There are so many different views on how to do this properly. I'm still confused. You are saying that your prop to pad distance needs to be "this", but another tuber says that your keel to cavitation plate need to be within an inch or less in height, and yet another tuber says you want the line up where the water comes off the side of your hull to be even or same as where your water pickups are. Pulling my hair out...lol. I have an older Basscat 93 model with a Yamaha ProV 150 on it. And it has issues coming outta the hole. So I got to looking to see if my motor was in fact too deep and needed to adjust my manual jack plate. So now more than ever, I'm a little confused...lol
setback changes the equation?...
I have a 16 ft alaluminum boat with a 70 hp with a 4 in pad to prop but it keeps a cavitation problem any ideals

Will prop to pad adjustment affect the steering? Like make it hard to steer at high speeds?

Nope.
Also depends on how far the set back is on motor ..you got 6inch 8 inch more set backs.. like I run pod bracket with jack plate

Ok so then did you raise your motor an inch or so? Working on this problem with a bass tracker.
So if i measure top of my transom to bottom of the keel to be 17 in can i use a long 20 inch shaft or do i need to use a short 15 in shaft?
@hollandsauce8422

Definitely short shaft
What’s the pitch of the boat when it sits in the water. Put leval on it. Then go from there.!!!!!😮
May I ask what is the gap between the prop and pad meant to be.

Depends on the boat. My Nitro should be 3 1/4 to 3 1/2. That’s typical of most bass boats.

Mine is pretty level but you only need the floor level for the 2-3 ft around the motor.

You don't explain where you get that 3.5" measurement? What's the formula that derives that distance?

@@clearwaterfishing I know where the measurement applies. The question is WHY is it 3.5" as opposed to 4.5" of 5.5"? Whats the science that makes that distance hydrodynamically the best? I see that 3.5 and other distances mentioned on various threads. I am hoping for some cool Hydrologist's explanation.

@@Ldltv Gotcha! So there are 2 things at play here. First is drag from the lower unit. More lower unit in the water the more drag. So obviously you want the least amount of drag, but you can’t have the lower unit out of the water. You still need enough for the engine to have water to cool but let’s ignore that for now. The real limit is around the air/water surface. The more your prop is out of the water the higher the rpm of your engine. In turn you also have less water for the blade to grab. So too high will blow out or cavitate the prop. So you want high enough to run your engine in the max rpm rating. Typically in practice that p2p distance is around 3.5”. Some as low as 2”.
