What's up ya'll, I'm new here on this forum & I have a few questions. I just picked up an 04 Johnston 200 fourstroke but I'm under the impression the suzuki made it hence why I'm posting on this page. I put the engine on the boat but I'm having issues with it. When I gun it or even just put the throttle all the way forward it's pulsates around 3500. I'm not getting any power out of it at all & I can't plane. I'm stumped & have no clue where to go from here as to why my engine is doing this. She starts perfect, idles even better but once she gets gas she bogs & doesn't go pass 3500rpm. It's been driving me nuts because all I want to do is catch some fish but I can't do so until this issue is resolved. Any help will be much appreciated!

No expert here and don't know anything about your particular outboard. But if it's an exact 3500rpm then it sounds like the engine might be operating in some limp home mode.
Any hints on YouTube? -
Preciate the comment. I posted on the suzuki outboard forum also & someone seemed 100% positive that it was a neautral safety switch. Not exactly sure where that's located but it's a cheap part & im hoping he's right. Thank you!Originally posted by brw0513 View PostComment

Having retired in 1991, the design and circuitry of your engine is foreign somewhat to me, hence my hesitancy in replying... However... the "Neutral Safety Switch" pertains only to the electric starter solenoid on any engine, that is..... it allows the starter solenoid to engage only when the shift setup is in Neutral which has nothing to do with your problem.Originally posted by Elliotto7!

Since I'm here...... explain, describe in detail when you have time exactly what you mean by surging ie..... a very sharp up/down encounter if rpms (ignition)..... a slow/gradual up/down of rpms (fuel)..... a drop of rpms when you hit a certain rpm and it stays there (overheating, SLOW feature)..... whatever!Comment

Hey sorry about the wicked late reply. I thought I figured out the issue but apparently that's not the case. If I were to relate it to the three examples you explained I would say it's either the safe mode issue or the fuel issue. When I put the throttle ALL the way forward slow or fast it wants to take off but stops at a rpm between 3-3500 I'd say & it sounds like it's gradually up & down. I have a video of it but my phone won't allow me to upload it. So I'm trying to describe it as detailed as I can. I took it out today & the first time I gunned it the boat planed out perfectly & went wicked smooth but once I stopped & shit down the engine to get bait & went to go back out & throttle again it would not plane or go over the RPMS previously stated.Originally posted by Joe Reeves View PostComment

did you ever resolve this issue, because mine does the same thing?Comment

I did end up figuring out the issue! Turns out my fuel pump/ vapor separater was very dirty & had a lot of gook at the bottom. So I took it apart cleaned it all out & put it back together & tan fuel through her & haven’t had an issue since!Originally posted by gradywhiteman View Post
By the way. When you seperate the assembly be sure to keep the little filter attached to the fuel pump when you removed the bottom half of the fuel box.
Hope it works for yah!Comment
