Your going to need to provide more info than that. How about a serial number?

Re: year suzikie 30

hello jo here again on this motor i need to know what type of oil to use in the foot..<br />and what type of oil to use in VRO thanks jon

Re: year suzikie 30

It is a 1988 model. Lower unit fluid in the lower unit, TCW-3 two stroke oil in the oil reservoir. I'm a little confused why your dealer didn't have this info available.

Re: year suzikie 30

I'm not sure the answer to that. I have the same motor with controls and paid $500 American for it. That was a good deal around here. It ran fine when I got it, but needed a good cleaning.

Re: year suzikie 30

John_Star,<br /><br />I'm replying from your request in the other post. I'm by no means an expert at outboards. Anyways, I had the same problem you mention above with my Merc 20. It turned out the that float levels in the carbs needed to be readjusted. Float height and sink properly adjusted should fix your problem. Good luck<br /><br />Adam

Re: year suzikie 30

The "VRO" as you call it on Suzuki is held as one of the most dependable systems out there for auto oiling. On my DT25c I removed it fully when I had the powerhead apart for freshening. My thought is anything mechanical can fail and if the oiling stops you will ussually hurt a motor before the failure is relized. I had the flickering light problem at one time and found it to be the vent in the oil tank stoped up. It is a rubber piece in the cap, after cleaning the light stayed out after start up. Just an example of how the system can fail from a fairly simple problem, potentialy wrecking an engine.

Re: year suzikie 30

Re: year suzikie 30

I am a little confused as to which problem you are talking about. As to the light flickering that MAY be from a vacum being pulled on the senser where the small oil filter is, first item in the oil line after leaving the tank. The wires on the sensor wait for contact by a simple switch in that small filter housing. Unplugging the wires would be a simple test BUT if there is a problem with oiling an engine could be wrecked. You might want to tank mix at 50:1 until findng the problem. The extra oil will not hurt anything.The only things that turn the light on on my tiller 1991 dt25c are the oil filter and tank level (both eliminated now), water senser in head, and rev limit.<br /><br />For poor open throttle performance, I would investigate fuel then spark. When was the fuel pump checked last. It is rebuildable. You MIGHT see an overly wet #3 plug if the diagram has a hole. Fuel line and primer bulbs can cause grief as well. <br /><br />If it is fuel related I would try to find it before much more run time. Lean fuel charges are hard on the piston tops.

Re: year suzikie 30

jleus thanks again.. BTW your doing real well in support here, im pro in motors music bizz<br />25 yrs .. pitty i dont know suzuki motors...<br />ok il chk all of the above .. am i to understand u removed ur vro>>?? il chk vacum and<br />get back to u .. i want u to know i was mixing <br />250ml to 24l and the vro is taking oil ..mi local dealer who middled the motor. has agreed to help me.. thanks any more hints.. whats a carb kit cost there and a head gasget..

Re: year suzikie 30

Yes I eliminated all that has to do with the oil injection. I had the motor apart for rebuild and tapped and plugged all the fittings in the front half of the block and plated over the pump attachment point. The gear that the pump was coupled to was left installed to maintain the volume of space in #3 cylinder. These are real strong motors and there are some design advantages in a three cyclinder as far as scavanging exhaust gases and drawing in a new charge. I run 40:1 synthetic in the tank and spin the motor up to 5800 rpm with my current prop. <br /><br />Carb kits are in the $25.00 (US) range but you don't get anything but the o-ring on the bowl and a new needle which is all metal and should be OK unless pitted. Head gaskets are around $20.00. I know these motors tend to back out head bolts and do check my head bolt torque frequently. Water ingestion hurts.

Re: year suzikie 30

jleus.. jon here ... im told by suzuki dealer that there is a strainer at bottom of the vro<br />can u look in manual and tell me howto remove the vro<br />+ if u have the manual.. it would help if u could email<br />me the pages i need .. btw the motor ran real good<br />and topd out near perfect.. im sure the vro is the main problem,, again thanks for the time

Re: year suzikie 30

Please describe the info you need from the manual. I am almost certain you will NOT find a manual giving instructions on removing the oiling system (VRO....which is actually an OMC term)what Suzuki calls "oil injection". I eliminated mine while the engine was disassembled. Removed the emulsifyer(sp) connections, drilled out the injection tubes, tapped and installed threaded plugs and epoxied over the holes on the exterior. Except for the homemade plate over the oil pump attachment and the mounts for the oil tank, you can't tell there was ever an oil injection system.<br /><br />To clean the filter in the oil line....1)unbolt the trim piece the rope pulls through 2)remove the three bolts that hold the oil tank on 3)holding the rope out of the way pull the oil tank away from the motor and wire it to something in a position that the oil line exiting the bottom is accessable, you may have to get the wires to the tank level switch and the switch on the filter out of the wire holders 4)four (or was it three)little screws on the filter need removed and the filter splits...the gasket and the little nuts and screws can be a pain. Have rags or paper towels handy, hemostats on the soft oil line helps. Clean filter and reassemle. Continue running you oil in the fuel tank until oil use from the injection tank is certain. <br /><br />Seems strange you found performance by working on the oil injection. Did you work on the carbs?

Re: year suzikie 30

jleus good post .. were doing VRO tomorow ..<br />perfect info.. ok we wana set the carbs and omc<br />pro did ( off the cuff) i wana know exauctualy <br />how many turns i back out set screws for carbs.<br />il keep u posted btw boat topd out again tonight<br />.. were getting closer.looking at the carbs next!!

Re: year suzikie 30

Both my manuals say 1.5-2 turns out from lightly seated. I have set mine at 1.5 with no troubles with transition off of idle. As I understand it they are called Pilot Air screws and function at idle only. Fewer turns out (less air) richer mixture, more turns out leaner mixture. There is little in those Mikuni carbs to fail. Use some care in seperating the bowl so the O-Ring can be used again. I "wet" the O-Ring with a little grease and re-use without failure. If the carbs were not flooding the floats and float settings are OK, just use some care to not knock them out of adj.. Good carb cleaner in all the holes and passages and compressed air. Take the screw you asked about AND the small jet next to it, as well as the floats and needle valve, out to ease cleaning. When the carborator is wet with cleaner and while blowing out with air I have seen some leakage (bubbles) coming around the soft welsh plug on top. Don't worry about it, Mine have not had a problem.<br /><br />Don't hesitate to pull the carbs off and disassemble and clean. There is no "tricks" to getting them back together. If the carbs have some varnish or trash and you lean out a cylinder the results can be costly.
