you have still not did post #28 yet..if you want to solve your problem you are going to have to do the needed test.

Post #38 oil sensor will not restrict rpms. The only sensor that will restrict the rpms is the temp sensors.

Re: 2000 Johnson 225 will not go on plane.

I am not getting a warning light to come on. My manaul said that I should do a blocking diode test if the warning light doesn't come on and goes into slow repeatedly. Could a bad diode be causing the problem. Ill try and test this weekend and have ordered a dva adapter so check the ignition.. Thanks you everyone that have commented on my post. I greatly appreciate the help and advice from all of you.

Re: 2000 Johnson 225 will not go on plane.

ok so when my motor started acting up again, I pulled the air intake off and sprayed carb cleaner in the carbs and she took off. Mostly on #5 cylinder. I took the carb off but she looked cleaned. ran carb cleaner and a wire and blow out with air. havent tried running it since I have did that but Ill see tomorrow

Brownmule69, Are you having any luck?

I was thinking about the issue a couple of days ago and I suddenly remembered a similar issue that my dad had a dozen years ago. He had a mercury outboard and it had problems, in which he changed everything he could imagine. It was not as complicated as what the motors are today, so the big parts was the "power paks" or switch boxes, and the stator coil.

The problem was that he put on an aftermarket stator coil.

We took it out on the lake and it ran like cheetah for about half a day, then the main power cut out and it was down to running at about half speed,if that.

Well, my Dad was "is" a stubborn fellow and instead of taking it to a mechanic, he worked on it for a couple of years before finally taking it to mechanic. We had to suffer!

It's hard to remember exactly what was damaged, the stator or power packs, but he had to replace the stator and power packs.

What I learned was that there is a low speed winding and a high speed winding in the stators. I think the high speed circuitry in the power packs were damaged and I think he had to replace it all.

The question would be, is the high speed winding in the stator coil intermittant on you and cutting out, thus reducing your high speed power?

I know you have been in a quandry and I am just "grasping for straws" on what the problem could be.

Keep us informed.

Best of Luck

Re: 2000 Johnson 225 will not go on plane.

Ok Guys this is what I found. I was on the lake with the air intake off the carbs and I let my girlfriend drive the boat while trying to go on plane. It just sounded as I wasn't getting enough gass so I had some carb cleaner in the boat and sprayed it into the carbs and she took off like a rocket. After I sprayed the carbs the boat seemed to run fine as if something/carbon was on the reeds or something. I took the carbs off the motor and cleaned them again but they werent dirty nor could I find anything that would be clogging them. I did adjust the carb by the book but I think I am going to have to tweek it a little. Now when my livewells are full and the tanks are full with two people in the boat. It takes it a while to get on plane.

Ive been having the exact same problem on my 96 johnson 225. Except mine happened after I had a plug go bad and the tip actually burned off of it and I heard it exit the exhaust so i replaced all plugs. Could this have Fuc*** up the cylinder. I a going to run a compression check soon. Before I had a mechanic clean the carbs and replace power pack.

I had a similar problem went about it the same expensive way turned out to be a clogged pickup in the fuel tank.

I had a similar issue with my 95 Johnson 50 hp, started and ran fine, but wouldnt plane out... but If I pumped the primer it would take off.

Come to find out... I had the float level set wrong, not sure if the 225 has the same type of float bowl?, but its worth looking into.
