Predator 459cc stage 1

12x32 predator 459 stage one. 27mph. Better, longer videos coming soon. Too cold for much right now. Stage 1 was worth every cent spent on it

[@backwoodshomestead]

That thing is a rocket dude! what kind of mud motor kit is it? where did you get the stage 1 kit?

[@codylanning1524]

Feather lite surface drive. It’s a predator 420 Stage 1 kit with a .046 jet. The pipe is a Robertson torque tube

[@peaceloveandgeckos]

Hey man someone probably already asked I looked couldn’t find exactly so I’m going to ask again sorry, I got the same setup minus the stage 1 can’t find anything out there for the 459, do you mind telling me exactly what parts you got on yours for the stage 1 and where I can get them, thanks

[@codylanning1524]

Intake side is the same as a 420 so Amazon is where I got my air filter and adapter. Pipe is a Robertson torque tube and when I called to order I told him it was a 459. Only difference is in the exhaust side is the studs are slightly wider on the 459. So if you have a way to slot the holes on the exhaust flange, any 420 header will work

[@bp30656]

Does your clutch chatter if you have prop submerged all the way in the water trying to go slow in no wake zone? Thanks.

[@codylanning1524]

Yes it does. The only thing I don’t like about the kit. My clutch ever goes out I’m going to see what I can do about an electric PTO clutch for it. I have tried everything to get it not to chatter like that and nothing I did seemed to help

[@bp30656]

@@codylanning1524 same here. The guy at mud skipper told me the motor was sitting too low in the water but it planes out fine and prop sits half in and half out when on plane. I try and trim mine up when easing along.

[@codylanning1524]

@@bp30656 I’ve never tried that. Mine trimmed all the way up with me not on plane, my prop sits about half way in the water. Only no wake I have to deal with is right at the boat ramps so it don’t bother me too bad. Usually where I’m going I have to stay on plane to make it in anyway

[@OutdoorsWithBink]

When I crank mine up it idles going 8mph mine doesn’t just stay still when I take my hand off the trottle

[@codylanning1524]

Dumb question, it does have a clutch right? I think some of them now come without a clutch and is straight drive. Second, back the idle screw out until the prop stops turning.

[@mississippioutdoorsman1]

Is the .046 jet running good for you?

[@codylanning1524]

Spark plug looks perfect to me. Runs great and strong.

[@rockymountainy7816]

I'm planning on doing this with my jon boat. Did you remove the governor off the engine or did you just put on the stage 1?

[@codylanning1524]

Just stage 1. I do NOT recommend removing the governor on a mud motor. Hit something and blow the prop out of the water you can blow the motor when it over revs

[@grantcamacho2687]

Where did you buy your stage one and did it make the engine run funny in any way at all

[@grantcamacho2687]

Nevermind other comments answered my first question but sofar the jet is performing well?

[@codylanning1524]

@@grantcamacho2687 runs perfect

[@timothydelahaye7743]

did you have to remove the governor inside the motor?

[@codylanning1524]

No.

[@hookedwithbryan]

I did something similar but you got it down packed how much speed you getting by myself im at 23

[@codylanning1524]

I cruise at 26. 27 with a little chop on the water and can push it to 28 but it starts getting sketchy

[@shotshelloutdoors3667]

So the 420cc kit will work on this?

[@codylanning1524]

I went to a surface drive with a 459

[@turneynicholas]

What's the difference in weight between that setup and the twister

[@codylanning1524]

Have to look it up. The twister I had was on a 212. I will say the 459 is not too heavy at all and I don’t care how much you build a small block, it won’t do what the big blocks will do. Borderline sketchy with that 459 pegged out. But with 2 ppl and a deer or 2 it will be about right

[@tylerczekaj860]

What performance gains did you get after stage 1? Considering this for my 459. Thanks.

[@codylanning1524]

First time I hit the throttle after I put stage one on it, I was sitting on the bench seat and ended up against the transom lol. Huge hole shot difference

[@codylanning1524]

Also gained 3-4 mph top end. Worth every cent

[@tylerczekaj860]

​@codylanning1524 wow. You convinced me I need this lol. Did you size up jet or keep stock? I know some guys run 34 mm mikunis and report nice performance gains.

[@codylanning1524]

@@tylerczekaj860 I just rejetted my carb. I drilled mine out myself and ended up being .046-.047” drill. The down side to doing a mukuni, you loose your governor. Not only does the governor restrict your engine rpm, it aids in starting. When I had the mukuni on my 212, it may have been a little more power but IMO wasn’t worth the cost or the aggravation of making it harder to start. I haven’t done mine but another cheap thing you can do is add a 8 degree flywheel key to your flywheel and it will make a difference. Moves the power curve of the engine up in the RPM range. I want hole shot and torque more than top end so I’m staying with factory timing

[@tylerczekaj860]

@@codylanning1524 that's true about the govenor, I didn't consider that. I think I'll just do exhaust air intake and rejet up a size and see how it is. Performance definitely isn't the best with 2 people and a dog with camping gear going up river, even in a 1436.

[@adamrichardson6002]

What stage kit do you have on it

[@codylanning1524]

Simple stage 1. Stock everything other than Robertson Torqe tube and air filter. Has auto lite racing spark plug and a .046” carb jet and Amazon air filter and adapter

[@daniellee9849]

Yoooo tell me how you did it? Carb and header? Where'd you get em? I'm wanting to get some more speed lol

[@codylanning1524]

Just used a 420 carb kit and ordered the header from Robertson Torqe tubes

[@daniellee9849]

@Cody Lanning the 420 carb kit from go powersports? Different jets?

[@codylanning1524]

@@daniellee9849 I got mine off Amazon. Think the jet I settled on so far is .046”. All I needed was the air filter adapter. I did notice that the studs are a little longer on the 459 so you will have to put some washers behind the nuts to take up Space. As far as exhaust, the flange is different from the 459 and 420. If your go with Robertsons tubes, make sure you tell him when you order it’s for a 459

[@daniellee9849]

@Cody Lanning I'm gonna order on Friday. Been loving this kit so far. Had some stuff rattle loose but it runs great and gets me where I couldn't get with an outboard

[@codylanning1524]

@@daniellee9849 yeah it does pay to use some lock tite on the kit. My main issue was the clutch cover. The bolts stripped out had to re tap them. Other than that the kit is solid. My only concern is if the clutch goes out, last time I checked mudskipper don’t offer a replacement yet. I’m looking into fitting an electric pto clutch so it will idle in gear better

[@THATMONKEYBOY1]

How’d you mount that stern light?

[@codylanning1524]

Made a plate out of an aluminum sign and ran wires under my floor up one of the ribs up to it. Had the attwood AA lights but I run 50% of the time in the dark so I just went all out and did it right

[@THATMONKEYBOY1]

@@codylanning1524 looks great

[@allenmcilwain8591]

What is your prop size and pitch?

[@codylanning1524]

It’s a 9” standard like comes with the kit. I want to say it’s a 5 pitch but don’t hold me to that

[@RA-zl6iw]

I wonder what I did wrong on mine. I started with a 459 predator, added the 34mm mikuni (knock off) Robertson torque tube, no governor, on a fairly light 1540 aluminum jon boat, and it’s a total dog. Gets to about 8mph with just me in it. I’m confused as to why.

[@codylanning1524]

If it was reving out like it should then needed bigger prop. If it just lugged and wouldn’t rev needs to go smaller prop. Also idk what kit you had either. I know the older stock twister kits came with a 3 blade. For speed and running half out of the water it’s junk. If you have this same kit then idk what was wrong unless that carb wasn’t right

[@RA-zl6iw]

My kit is the feather light surface drive kit, same as yours. The engine will cause the 2 bladed 9” prop to cavitate at takeoff then it kinda grabs ahold but then the engine just kinda lugs like it’s not making any power. Also I’ve noticed that the belt is rubbing on something because there’s rubber in the clutch housing. It’s probably a combination of several things keeping it from running at its full potential. The thing should be a ripper with all I’ve done to the engine. Only had it out twice. I’m disappointed so far, but it’s probably something I messed up.

[@codylanning1524]

@@RA-zl6iw that belt rub is the belt slapping the side of the housing about half way down. You figure out how to fix that let me know lol. I’ve fought that battle for a while now and can’t get it stop. All I can say is don’t run your belt too tight or it will snap. That ain’t the answer lol. My bet is the carb. Maybe adjust the needle up or down. Check your spark plug and see if your rich or lean. Has to be that. My stage 1 will run cause the boat to run out from under you. Again, dig more into tuning that carb up right and I bet it will fly

[@RA-zl6iw]

Thanks for the reply/advice. Yea it’s definitely running rich. I’ve got another new 34mm carb I’m gonna try on it. I’ve also got a tach coming to see what kinda rpm it’s making….it’s not making many rpm by my ear. I’ve gotta push the prop halfway out of the water to get the rpm up. I would have thought the engine would have easily handled the 9” prop, especially since it cavitates at a full throttle takeoff. Something isn’t right with the carb and now I wish I woulda left the stock one on it. The positive part of it is I added a 6 gal tank and fuel pump up front for long runs. Thanks for the help

[@codylanning1524]

@@RA-zl6iw dumb question but you have got jets and re jetting this carb right? Also the needle that comes out where you hook the throttle cable to on that slide has adjustments on it also. Watch a KZbin video on tuning them things they are touchy. That needle needs to be lowered by the way it sounds to me. Also may need to go down on that main jet some
