    1985 90hp bottom end removal

    Don't forget to remove the "fin" behind the prop to get to that bolt too. Remove the rubber plug to get to that bolt to remove the fin, then you can get to the bolt that goes up into the exhaust housing "mid section". That's frequently forgotten and some folks have destroyed a lower unit by...

    2009 mercury 50 hp idling problems

    Running fine at WOT, but poor idle and trouble starting is usually caused by an issue with idle circuit in carbs. I've attached a diagram of our carbs. You'll need to remove carbs and take off the top cover #10 and clean out the small passages under that cover. Also,take out the adjustment...

    1985 force 125 compression test

    Before getting too worried, I'd go to a national auto parts store and rent a good compression tester and test again. All of those numbers seem high. Let us know how the retest goes.

    1959 Jonny 35

    You do have a little cleaning to do there! It's a little crusty in there! I'm sure you'll have it clean as a new one soon. If it's running well, then cleaing is all that's left to do, right?!

    Motor shuts off but turns back on after trimming down

    Now, I don't have fuel injection on my 1999 115 Yamaha, but it does have electronic ignition. 4 stroke fuel injected motors might be different. It would seem odd to me to have a charging system that keeps your battery charged while the motor is running , but that same charging system can't...

    Motor shuts off but turns back on after trimming down

    Battery voltage is about 14 when running. That's because it's being charged by the charging system. The starting system that powers the motor once it's been started by the battery. When my trolling motor battery is completely dead, I crank up my motor, disconnect the battery cables and...

    Tension Spring

    I've attached a link to a video of a rebuild of the carb I think you have. I've also attached a parts diagram where you can order parts needed. I'm guessing you're talking about the spring that's in the primer. There's a small spring and also a small steel ball. It's a check valve, I assume...

    1977 evinrude 15hp add electric start conversion kit

    And don't throw it away once you get the parts you need now. That parts motor will pay for itself over and over again!! Smart purchase! I bet Racerone has 20 or 30 "parts motors" on hand. He's constantly got the parts that folks here need for older outboards!

    Motor won't turn over

    i worked at a service station almost 50 years ago. We used to be able to buy a solenoid rebuild kit! It cost about $3 at the time. The solenoid was actually held together by long screws and you opened it up, replaced the disc that made contact, the spring and you used a little sandpaper to...

    Motor won't turn over

    To answer your question, the solenoid is basically a switch. It can't be wired incorrectly. When current passes through the small wires, it activates an electro-magnet that causes a disc to slam down and create contact between the two large contacts. It's a simple way to use light low...

    yamaha 25hp starting problem

    Did you disconnect the battery to do this work? If not, I'd check all fuses. Should be an inline fuse somewhere under the cowling.

    Yamaha cylinder bore

    I've done that on a 115 Yamaha. Ran great with no problems after that. Then Hurricane Matthew came to Savannah and dropped a 60' oak tree perfectly lengthwise on top of my boat! That was the end of that boat! One of the trailer wheels shot all the way across my backyard an the other one Put...

    Motor shuts off but turns back on after trimming down

    Fire up your motor and remove the battery cables. It will still run. I know it will on OMC and Yamaha motors. My son had charging problems with his 70 HP Evinrude. We'd meet on a barrier island and spend the day. Sometimes his battery would be drained and wouldn't start his motor. I'd...

    1990 90hp stubborn overheat problem

    I posted a similar problem on this website and several others. On one site, a guy had the exact same boat and motor as mine and he had figured out the problem. I have a live well in the back of the boat and I use it to store my anchor. SInce the rope is tied to a cleat on the transom of the...
