    Yamaha 250 not pumping oil

    I have a 96 yamaha vx250 2 stroke carbed motor. i had to replace the battery today and when doing so mistakenly hooked up the battery cables wrong. The engine and all gauges work fine but after 20 minutes my oil alarm went off. Oil is not pumping from the remote tank to the one on the motor. Is...

    Trim Cylinder caps stuck

    I noticed some oil around the dust seal on my trim cylinder. I replaced the trim motor today. When I push in on the trim rods I see a very tiny amount of fluid bubble up around the dust seal. I assume this means I have a bad seal? Since I already have the trim and tilt off to replace the motor I...

    Yamaha Starting + tilt/trim problem

    Just as the title says I went to start the engine for the first time this season. I only get a click when hitting the trim/tilt switch and there are no alarm sounds when turning the key to run. I do hear a slight buzzing/humming soud when in run but thats it. The motor will turn over but I...

    Head bolts Stuck!

    I'm attempting to replace the head gaskets on a 96 yamaha 250. I have 2 head bolts that don't want to come out. I assume if I break them off in the block I'm looking at pulling the powerhead and having it drilled out by a machine shop. Most likely I'll run into more broken bolts trying to do...

    Cylinder head Gasket(s) on 96 250

    I'm looking to replace the head gaskets on my 96 250 outboard but I'm not sure what I need as far as gaskets go. The diagrams ive found online are pretty hard to read but from looking at them and the motor itself it appears that I would need 4 gaskets altogether. There is part# 61A-11181-A0-00...

    Yamaha Carb Rebuild

    I was just quoted by a shop for 16 hours to rebuild 6 yamaha 250 carbs. The motor is a 96. This sounds like quite a bit more time than it should. What do you guys think? I know on cars there are publications that list the amount of time it takes to do certain jobs like timing belts, but what...

    Bogging down and too much smoke

    I had a few issued today when out on the bay. The first thing I noticed was that it took forever to get the primer bulb hard. In fact I almost gave up. Then as I was running it was bogging down especially under 3500 rpm's. I gave it more gas and it seemed to run well over 4000 rpms. When we got...

    Yamaha Oiling Problem

    I finally got the boat in the water yesterday and it ran great. 96 Yamaha 250. When I got back to the marina I noticed an oil slick behind the boat. I pulled the coweling off and found that the engine's main oil tank was overflowing. I did a little web research last night and it seemed that...

    Yamaha 250 Choke

    Maybe a dumb question but its a new motor to me. 1996 yamaha 250 carbed. Whats the procedure for setting the choke? My old merc was done by pushing in the key but that doesn't seem to be the case on the yamaha. There is a small switch below the ignition key. I'm guessing that may be it but was...

    Bottom Paint Prep

    I'm about 90% done removing years of old ablative paint from my wellcraft sportsman (fun day) I'm down to blue stained gelcoat with some old paint residue. At this point I'm not sure whats left to do before putting on some new multi season ablative. The hull which is an 85 has no blisters and I...

    Winterizing question

    At the end of the season I bought a new to me yamaha 250 two stroke. I believe its a 95 or 96 salt water series 2. The marina where my boat is stored was supposed to get it rigged and running but they got busy pulling boats for the season and have yet to do it. At this point I'm not sure if...

    Swapping to a newer Yamaha-what's needed?

    I'm replacing an 85 yamaha 225 with a 96 250. I'm pretty sure the controls will be ok but what about the wiring harness? Will I need a new harness or adapters to make this work?

    Yamaha Corrosion

    I'm hoping you guys can help me decide whether or not to scrap the engine on my new boat. Its an 85 yamaha 225 with the typical corrosion issues. If the compression test is bad then its gone but if its ok then the choice gets tougher. The lower unit has a pretty big crack which after lots of...

    "awesome" boat-not!

    I can't believe people have the nerve to try to pull things like this. On craigs list maybe but on ebay come on. I checked out this "awesome" boat today to find a complete basket case with a very bad transome and lots of soft spots on the floor not to mention the rest of it was beat to hell as...

    Idle Surging

    I just put the boat in the water today. It was idling fine in the driveway and was idling good at the ramp but then it just died. When I restarted it it kept on surging up and down. It would smooth out for a few seconds and then start surging again. I took it home and went through the carbs but...

    Leaking fuel when tilted up

    My carbs are leaking quite a bit of fuel when the engine is fully tilted up after running. In the past it always leaked a bit but it seems to be much more than in the past. I'm wondering if the floats are sticking since it sat all winter? Or is there something else that could cause this problem?

    Water coming out of exhaust

    Like the title says I have water coming out of the top exhaust port on my 91 merc 135. This never happened before so I assume i screwed something up when replacing the impellar or t-stats. What do you guys think I should look for first? Thanks
