I need help with a 2 stroke 40hp suzkie bad idle motor has been tour down 2 times carbs has been rebuilt .

Where's part #1? I just ordered a set of reeds for my 2.5L merc from Chris and he told me to watch ur video

Do you think the nose cone is the problem? JW. I wanted to put one on my tohatsu M50D, just worried about over heating. Thanks in advance!

I put a set of boyson power reeds on an old Johnson 115. Picked up 400rpm's on the top end, same prop.

cool man!

This is an older video but I like you're work. I'm in the middle of doing a 95 bullet that's pretty rotted. I'm trying to do what you are. No wood, no expanding foam. Not cutting all the balsa out, but most. Just a fast fishing boat. Anyway, keep up the good work.

Poppet valve is the one When thermostat are bad water doesn’t enter to the chamber and overheating and poppet valve rubber seal get melted and water never go inside

Man i think my is doing the same thing do you have a facebook or something i coild message you on to get some advise

Does the crank on this 2 stroke have full circle needle bearings on the main journals?

This thing is awesome and almost made me buy one. Got a Bullet 21xdc instead.

Did the switch box fix the issue with it misfiring and over heating

Awesome engine!! 😁💪🏼🥳

Red lock tight ? That doesn’t sound like a good idea to me.

So its not a problem putting 20 volts dc to the pump and injectors? Don't they normally run on 12vdc?

I have a 2.5 thats been worked/ported to 225 promax specs but has wmh2 carbs on it now. Do you think i can tune those to get the most out or do you suggest a different set of carbs, or convert to efi? Love the videos btw.

What do you mean set your timing advance accordingly? Please elaborate...

I been researching for awhile ... I'm 90% sure this is it! Thank you

Are those CDI spark plug wires?

Sounds legit! I love me some 2T outboard. Keep er' pointed in the right direction. 👍🏻

Great boats but really sensitive to setup and weight.

Boyesen or vforce all day

Hey! Seems like you know what you are talking about. But could you make a more detailed version in a longer video?

I would've boiled the block in a de scaling solution you got all that scale in the water jacket area around the cylinder bores all that's gonna do is overheat the cylinder walls again

These 2 cycle motors are so bad for the environment there should be a mandatory phase out on these

Thanks for the video! I just received my reeds and stuffer kit from CCM. I noticed on the first block that there is a slight gap between the block and some of the reeds, showing light through. It seems to be better if I flip the reeds over, but still a gap on a few reeds, about 10 thousandths. Is this acceptable? There were no gaps with the stainless steel reeds. Thanks for your help!

Just for an info - in any case with a softer reeds you will have good idle and middle, with a stiffer reeds you will have better middle and +500-600 RPM on top. You will not have any power improvement with any reeds, just a change of engine "feeling" how it behave on a certaine RPM. This is a rule for 2-strokets... All the best from Russia.

I have the 150XL SWB Saltwater Series and was able to remove the heads, pistons and cage bearings then honed the cylinders without removing the power head.

I am going to try this my self picking my boat up from the macanic that told me 7,000 to rebuild and going to do it myself this video made it look easy i loved it

Ware are you located at i have a 1996 murcry power head i would like to get a price from you i was told today i have no compression on cylinder 6 the motor cranks right up but no compression i was told

I'm enjoying your videos though I've only seen 5. Love what you have going on with the Frankenbeast. You're doing what I'm researching to begin doing. My dad raised me up with the Tower of Power. It's 40 yrs old and still runs like a Swiss watch. I'm ashamed I've only recently turned my eye from the L6's to realize Kiekhaufer's design wasn't the only outstanding Merc. production. I'm currently loving everything I've seen on the 2.5L Mercs. Diggin the Frankenbeast ! I'd be hollerin WOO HOO TOO!!! LMBO. Now, watching this video, I can assist with the frp aspect of your hull refurb. 25 yrs Engineering Specialist. I'm curious as to how you laminated the transom panels. It appears you are using possibly polyester putty (1:02.0 - 1:34.0). I hope you did not. Feel free to message me if you'd like. You can teach me a bit about the important part, the 2.5L

Was the compression ok when the reeds were bad?

Was your compression good with the bad reed valves

At 13:13 we see that engine suddenly stops moving when you were trying to start the engine. This fact alone should be enough reason to suspect of an out of time spark which causes a strong instant brake.

Very interesting what you said during one minute between 14:45 and 15:45. You get a spark at the right time but also another spark 90 degrees before the right time, since the flywheel is rotating clockwise. The extra spark is probably what causes the out ofvtime pop that you hear, what causes the overheating cylinder when gasoline tlwas forced to be burnt inside the cylinder instead of at the exhaust manifold, and what caused the engine to stop rotating suddenly sometimes when you attempted to start the engine also. Everything makes sense, if we understand that gasoline must be burnt at the exhaust manifold but never insude a cylinder! The explanation of how an engine works is false. Piston is not being pushed down from the gases after each ignition. Those gases are being formed after the gasoline is burnt at the exhaust manifold. What causes the piston to be pushed at the right time is something else, an instant pop that does not increase the temperature, not the gases from burnt gasoline that do increase the temperatureof the exhaust manifold outside the cylinder.

thanks for the video ima do this at home

I know you're trying, but this is utterly useless. KZbin shorts are BS. Make a proper video.

Hey man your a life saver i have the same machine with the same problem. What are the chances you can share the file ??

I got a 225 black max that i just blew up, put a hole in the side of the engine, is there any cheap places i can get parts from that you know of ?

Nice 2.5 Eli racing

What happens typically when one of these things runs out of oil and they quit does it usually require the whole engine rebuild or can you just re-ring it

Gnarly.

Great videos. The plastic shavings you found during tear down lead you to the plastic oil gear on the crank as root cause for the gunk build up and low compression. Does Merc offer a replacement part for the oil gear that is not plastic? Replacing that gear would be a bit tricky since the crank assembly would have to be torn down, certainly involved. Is there is a fix to the root cause? If not it seems that you really have to stay on top of your engine and catch these types of failures before it becomes a real problem.

Great video, much appreciated. My 135 has 90 compression and about to take it apart and rebuild it.

brother I am trying to find you on scream and fly, says your name is the same, can't find you, need a little more info, what was causing the double fire? I think I am having the same issue on my 92 2.5L

I used them bedroom there only good at cold start up I never noticed any better performance

How can I contact you

Where are you located?

Hahahaha don't do this at home...... but it's fun. Does this have a nicaseal sleeves I. It?

Did you drill the Jets Out on the Frankenstein motor I've cut my chest out and open the rock slots will it be enough fuel

Just did both reeds and stuffer kit on an oil injected 2004 Yamaha V4 @ 490hrs which was turning 6,000 nicely. The reed replacement was mainly preventative maintenance and for piece of mind (the OEM reeds were in perfect condition when removed). With the stuffers I looking for better 2000-4000 performance. After install I lost about 5% off the top end. Idle doesnt seem any better and is actually about 75rpm lower which may just need a turn of the screw. I've only run it about 3 hours in poor sea conditions which made it difficult to report the mid range performance. Always started well and still does. Will update as the hours accumulate. 🚤
