    Yamaha 200ETXN 1984 Stator Values

    Hey yall, I am having a problem with no fire on my top two cylinders on the port side of the engine. I tested the ohms using the CDI website for reference. Everything checks out as it should except for the ohms between the red/black stator wire and the blue. CDI says that oem should read between...

    704 Binnacle Control Trim Not Working

    This is an old 704 binnacle, that has individual leads instead of a plug for the harness, and it has decided it no longer wants to trim up. I can swap the green and blue leads in the harness and use the toggle in the down position to trim the engine up. I think this means the fault is in the...

    Yamaha 200ETXN Surging Idle

    Hey fellas, I hope yall are having a great fall so far. This is the first time I have actually run this engine in the water after it sat for quite some time. When at idle I am hearing audible spikes in rpm and its not running at full potential. If I mat it then it falls on its face and did...

    1998 VP Cobra SX Gimbal Selection

    The outdrive is a 98 Cobra SX powered by a 4.3GL and I need a new gimbal bearing due to a hole in my bellow and water intrusion. I'm uncertain as to what to order though since I don't have an initial on my ID plate. I will attach a picture below so every detail will be included. I'm linking a...

    Yamaha 200etln 2-stroke bad coil?

    Pretty sure I have a coil going out but wanted to check with yall before I ordered parts. The way I ohm'd these was to attach the negative clamp to the lead going into the coil from the CDI and the positive to the contact in the plug boot. They all read about 2.50k ohms but one came to 6.57m...

    2000 BF90 Carb Starter Amp

    I am looking to add a fusible link to my positive battery cable but am not sure what size would be appropriate. Battery cable was damaged and thought this would be a good quick fix while I wait on a new one to come in. Thank ahead guys.

    Throttle and Timing Advance

    I have an 86 yamaha 200 that sat neglected for years. I got it running but the timing would not advance when the throttle is applied (engine off). I took the linkage loose at the arm and saturated the timing assembly and got it moving, but not easily enough that it moves with the throttle. How...

    1986 Yamaha 200 Slow Starter

    Hey Yall, I'm rehabbing an 86 Yamaha 200 and I am seeing hot battery wires and a slow starter that results in a no start situation. If I put a battery charger on in spins up faster and starts right up. Battery is new and so are the battery lugs so am I looking at bad cables or starter? Thank...

    1998 4.3GL VP SX Slipping

    So my boat was running great all day until I came off of plane and started high idling for 20ish minutes. Then I felt three bumps at irregular intervals over the course of a couple of minutes. I accelerated to 35mph and drove without incident for 30ish minutes until I made it home. I pulled...

    Dead Gas Gauge

    I know this has been beaten to death but before I throw a new gauge in I wanted to see if yall agree with my assessment. With the key in the on position I am bottomed out on the gauge. I pulled the contacts at the tank and cleaned them and tried the ground out trick with no change. I moved...

    98 4.3 GL Fuel Pump Connector

    Hey all! I have owned this boat for a few years and never knew anything was wrong until it cut off on me on the water and just refused to fire again. Turns out the harness connector for the fuel pump no longer stays connected to the pump. It will just slip off on a whim. I zip tied it to get...

    1984 Yamaha 200 ETLN 2-stroke no spark

    I have once again come to ask for you guys help. I finally got it running and then lost all spark while fine tuning the carbs. My question is what should I check to trouble shoot the CDI and the control box? Is either more likely to fail than the other? The old CDIs are impossible to find and...

    Yamaha 200 ETXN 86 2-Stroke will not run.

    I had another thread but was having a different issue. Seemed more appropriate to start a new one. My engine sat for a few years before it came to me. I have been trying to get it running to no avail without spraying gas through carbs. Once I do that it will fire right up with no issues. I...

    2004 BF90 No Crank Condition

    My parents have a Honda BF90 on a scout they were using at the beach last week. All week long it did great with daily use. They took it out fishing Friday and had to get a tow due to the no start condition. When you turn the ignition to on everything acts as it should, but when turned to crank...

    Yamaha 200 ETXN Carb Draining Gas

    Hey Yall, I have a 200 ETXN that was gifted to me that I am finally getting on my 74 Mako 20. I cleaned out the carbs, new NGK plugs, replaced the fuel lines, and deleted the oil pump (it wasnt complete) in favor of premix. My new problem is that when I pump the bulb it wont hold pressure...

    Noisy Intermitent Trim Pump

    My trim on my 98 4.3gl/sx, with the old style pump, has decided to be less reliable than I want it to be and I want to see if yall concur with my diagnosis before I change anything. The relays click when toggle is engaged but it takes multiple attempts before trim motor kicks on. When it does...

    Honda BF90 Intermitent Alarm

    My parents picked up a 98 Scout with a 2006 BF90 retrofitted on at some point. Boat ran really well for a few months and my brother hit a mud flat in it. This is when he first started noticing the alarm. I cleared the mud from every or oriface and I have pressurized water flow. It buzzes under...

    Setback Bracket Mako 20

    I have a 1974 Mako 20 with a 22" transom. I was given a 1986 200 25" Yamaha that needed a new lower that I happened to have. Will using a fixed bracket to gain the extra transom height I need be a good idea? If it is a good idea how big of a setback should I go for? The boat seemed pretty well...

    Repropping 2005 Honda BF90

    Hey guys, I just picked up a Scout 162 with a 2005 Honda BF90 and need to find a new prop. I have that famous lean out condition right after I apply the throttle that I am trying to work around. Right now it has a stainless 3 blade 17 pitch and I would like to switch to a prop to allow the...
