Budget Jon boat speed and prop test 35HP 14' Jon boat its FAST

Budget Jon boat speed and prop test 35HP 14' John boat its FAST
My budget jon boat project series wraps up with this video of the initial test runs. The boat is a cheap 1436 riveted flat bottom which is powered by a 1979 johnson 35hp outboard. I went into this project with a goal of reaching 30mph and being able to run in 6' of water. I am happy with the outcome and had a ton of fun with the project. This may be the last video of the project series but it will not be the last you see of this boat. I will be using it for those fishing trips that require ultra skinny running as well as for river days with the family. Thanks for watching!

I’ve a got a 1987 25 hp evinrude on a 2018 1436 Alumacraft light jon. It easily hits 32 or 33 but i have gotten it up to 35 a handful of times. No tilt trim no jackplate just trimmed all the way up with a passenger sitting on the back bench with me and 6 gallons of fuel up front! Great video

[@CampCatch]

This boat was much much faster later on with a modded merc 25. The omc 35 was hurt and let go with a piston failure not long after this video.

[@user-qp6ud8un1v]

Friend, l think the other person was right, drop the motor tilt all the way down and lower the jack plate all the way to then you have more motor in the water and the prop will react differently to 😊😊😊

[@jonnun7713]

Bro! I know this is old!, but man I was right there with you I have a 10 foot with a 20 horse on it and it rips just like that

[@marysaussy3793]

She rips!!! You should be proud of this one! 😘

[@DomesticGangsta]

Great job with this!

[@CampCatch]

Thanks!

[@dadbeardtv3350]

this is friggin awesome. I'm def using your template when i start my budget jon boat. Paid $100 for it. Now I just gotta get it ready. i think it's a 75 sears robuck jon boat.

[@CampCatch]

Nice! My first boat was a sears sea king 12' with an OMC 9.9. I used to go out to the local spoil islands with my friends when i was about 10 years old. I loved that boat, wish i had it today.

[@Laserwurks]

Love subaru outback for towing my 15.5 jon

[@donniegray2288]

That prop seemed to help you alot.I have the same engine and a 14ft tracker Jon and a 16ft Lowe big Jon and I'm gonna order the same prop and try it.Also have a 25 Johnson too and I can use the prop on both.I hope my results are as good as yours!

[@CampCatch]

That 25 is the same engine as well with a smaller carb and intake plenum.

[@tintdr]

How did the stainless prop work out for you?

[@CampCatch]

@@tintdr it made a huge improvement, but its hard to say if thats due to the wear on the aluminum or because the stainless is just that much better.

[@donniegray2288]

@@tintdr made a big difference but it’s having carb issues now I need to do some work on it and I’ve got so many it’s on the list lol

[@SDGFL]

Drop the motor tilt down one more hole to push the fron down and control the porpoising. Think of power trim down.

[@CampCatch]

My next day of testing should show different results as ive added tabs and fixed a plug wire that was robbing power and about 400rpms. i will play with using that last trim hole if needed.

[@bassmaster0570]

Hey man I love the build and I have a 1436 Grumman that I’m building now and I have a 15 horse Johnson that I too out at 24.2 with I’m thinking about investing in a jackplate

[@CampCatch]

I love the onthefly plate. Follow recommended maintnence, spray grease the tube from the bottom every use and it holds up well.

[@tategasek1719]

All you have to do is drop the tilt pin one spot closer to the transom. That should knock that porpoising right out

[@furiousgarage]

cuz we need to go fishing in that

[@cadeherin188]

When you added the trim tabs after this did it help with the boat popping up and down love your boat man been looking for inspiration on how to build mine and you definitely hit the nail on the head👍one more question have to thought about putting float pods on the back like the mud boats just curious pros or cons

[@CampCatch]

Shortly after adding tabs i swapped to a built merc 25 so its very hard to say. The merc was a little faster and much stronger down low (due to being freshly built vs the worn out OMC). The tabs stopped the bouncing all together. Pods would have been my next move but i moved on to a bigger project and sold the Jon boat. I had a son and decided my free time would be spent with him rather then making youtube videos. I may vome back to it eventually once hes in school.

[@patrickfearon7942]

Where are you based out of? I just got my first jon boat and liking your setup. I’m down in Boca Raton/Deerfield.

[@CampCatch]

Im up in Palm Harbor just north of clearwater

[@rickarndt3895]

That old Johnson has had it throw it overboard

[@Dangbo3030]

It's still going as compared to the 4 strokes with inferior alloy. I had a mercury/tohatsu that was corroded inside the water jacket. I did buy a used Johnson/Suzuki 9.9 fresh water motor and I'm going to use it in both salt and fresh water. Definitely flush each use. I'll check it annually for degradation in the water passages.

[@josephauld6565]

Jack plate may help?

[@mchenryjeremy]

just need some trim tabs to kill the porpoising.

[@mchenryjeremy]

you then mentioned about the trim tabs at the end haha

[@RossHooge]

Where can I find a jack plate like that for my Jon Boat? I like the manual screw adjustment without using a wrench

[@CampCatch]

www.ontheflyjackplates.com On The Fly Jack Plates To be clear i have no affiliation with them but am impressed with their product.

[@maximumspeed04]

what kind of paint should i use to repaint my 16 ft job boat

[@jopark66]

i have a 1542 jon boat with a 25hp 2 stroke yamaha. i get 28mph no sweat with me and my wife in there. also mine is decked so its a lot heavier than yours. the best i've ever done was 31mph going down river with the wind at my back. you need a wider boat, it'll sit higher in the water and be faster

[@CampCatch]

The old OMC 35s were flywheel rated so the 35 is really more like 28hp in more modern stamdards. This boat has a merc 25 on it with some mods now, its considerably faster now. Also keep in mind that in this video i have 2 people and 60lbs of lead all the way up on the bow to keep the bow down, it has tabs now and levels out on its own.

[@CampCatch]

But speaking of a wider boat, i did get a wider boat, i got a 1648 fisher marine that im making plans for now.

[@casper3130]

idk that metal looked like it wanted to fold up running across that water.. that might be a reason jon boats are motor rated.

[@CampCatch]

It flexed a lot even with a smaller engine. It never sprung a leak even later on with a stronger engine on it and significantly more speed (about 40mph) it was fine. Adding trim tabs made it much more managable.

[@coltensawyer6761]

I’m doing the same thing with my 14 36 although I’m wanting and hoping to run a 670 predator long tail. How much does that motor weigh and does the transom flex ? How did you re enforce yours ? This is my first boat so learning as I go

[@CampCatch]

no noticeable transom flex however the omc 35 is extremely light at about 125lbs. Your bigger issue is going to be floatation. I do not think a 1436 without pods will handle a 670 long tail. You will likely end up taking water over the transom with even the smallest waves.

[@MrHabitat009]

Bro I just worked on your neighbors floors. His name is Brian he lives on the opposite side of the street about 4 house down with that small sailboat on the driveway

[@tyler-xh4be]

How’s the paint holding up?

[@CampCatch]

Perfectly. Its become very hard and its thick like an epoxy paint. Im very impressed.

[@CampCatch]

It did take a long time to fully cure, like a week.

[@rickarndt3895]

No you don't want to drop the motor 1pin you need to lift the motor off the stern 1" the object is not to put bow down you just need to keep it from porpoiseing and chine walking keep that bow up lift the motor up 1" or as high as you can without it cavitation trust me I worked for mercury racing team and try a couple different s s props

[@knightcustombuilds6988]

Agreed,the small v spray coming from the back tells me thd motor was too low.

[@stephenellis3609]

Did you ever figure out that without the weight of someone in the front, holding the boat lower in the water and causing more drag, you could probably get over 40 out of it with the right trim?

[@CampCatch]

That old OMC was worn out bad and ended up coming apart. Its got a merc 25 on it not with .20 weiscos, boysen reeds and some light port work. It does 39 with just me in it now, and is limited by the prop.

@@quentinsilas5912 HPS marine in Pasco county fl. in retrospect though going to a yamaha 3cyl 25 would have been cheaper and faster, especially if you have a bigger boat then the little low sided lowe 1436

I’ve got a 14x36 flat bottom im setting up with a 85hp and steering wheel in nose of boat

[@CampCatch]

My 1436 wouldn't float an 85hp, maybe with some massive pods. If i stand in the back with the merc 25 i currently have on it theres like an inch from top of the transom to the water. Id love to see yours when done, im sure it will be a rocket ship.

[@boostacoosta2505]

Mine must have taller edges I had a 10hp and with 3 200 pound guys in it, it was fine

What kind of jack plate is that?

On the fly jackplate. I've got nothing but good things to say. I heard people's concerns about them but from personal experience they are awesome.

[@johns.6570]

What pitch was your stainless prop?

[@CampCatch]

15 pitch

[@johns.6570]

Interesting I ran a old school 35hp on my rib inflatable with a aluminum 10x15 prop, made 36mph, I ran a stainless and got 35 mph, I’m thinking perhaps a stainless is too heavy for the motor to spin and thus the less speed, I don’t know for sure, I read that stainless steel props only really make a difference on motors 60hp and up I don’t know , can’t confirm this.

[@CampCatch]

@@johns.6570 not all stainless props are going to preform the same even with the same pitch and size. In my case the aluminum I swapped from was very worn out.

How wide is your 14'? I've got a 14'x60" deep V with a 9.8 4 stroke tohatsu but I'm only getting 18 or so. Wondering if I should go up in pitch on the prop.

[@cadbury4160]

My 1436 with a 15hp evinrude will do 27mph without a jack plate. I think I could hit 30 with a jp

[@CampCatch]

I know a guy in one of the OMC groups on facebook has a modded 15 all dialed in on a 1436 and does just over 30.

[@vivimu]

Lmao wearing gloves to go boating? That's a new one

I can go 23mph on my 1436 with a 9.9

[@CampCatch]

That old Johnson ended up having a damaged piston and low compression on one cylinder which is why it didn't run to its full potential. The boat runs about 40 now with a modified merc 25.

[@southernreelinngrillin9964]

Wat hp is your boat rated for? I was sketchy bout running a 25 hp mine is rated for 15hp

[@CampCatch]

Originally rated for a 15 but ive made some modifications.
