    2018 Yamaha 25 hp. 4 stroke will not run at slightly above idle.

    I guess my question now is about throttle response on a four stroke versus the two stroke. After the ultrasonic cleaning it runs very well but does not have the immediate response the 2 stroke has. It seems to be a slower throttle response. This is my first 4 stroke so I am unaware of the...

    2018 Yamaha 25 hp. 4 stroke will not run at slightly above idle.

    A heated ultrasonic cleaner has been used to clean this carburetor and it is much better now. It will not give the burst of a two-stroke but that may be the nature of a four stroke. Any insight on a carbureted four stroke would be greatly appreciated.Runs great except for a fast hole shot.

    1997 Yamaha C40 2 stroke tilt unit repair kit.

    My guess is the tilt cylinder is bad since the fluid pump is out of the top of the cylinder. On this particular model it is tilt only and no trim. It will not trim while under power.

    2018 Yamaha 25 hp. 4 stroke will not run at slightly above idle.

    I think I will try one of those as I hear the passages in a 4 stroke are extremely small

    They were disassembled and placed in a cleaning solution for 30 min. All openings blown through with compressed air and a small tip cleaner run the openings and then rinsed .

    2018 Yamaha 25 hp. 4 stroke will not run at slightly above idle.

    Motor sat on garage floor for 18 Mos. Before I purchased it from someone I know. I cleaned carbs, replaced fuel line and bulb and have fresh gas. Motor will start and run at idle. If you increase the throttle it will sputter and die. While running I can spray gas into carb while increasing...

    Starter motor turns when the up switch on the trim is engaged

    I will take a look at that first thing tomorrow. There is a covered junction box on the right side of the motor that may hold a clue. I am not very familiar with Yamaha wiring as everything else I own is OMC.

    Starter motor turns when the up switch on the trim is engaged

    I recently purchased a used pontoon boat with a 1997 40 hp 2 stroke on it. The t&t switch when pressed in the up position will make the starter motor turn. The starter won’t engage because there isn’t enough power to run both motors I presume. The tilt motor will run for a second and then stop...

    1973 Evinrude 25 hp fuel pump

    Can I use a newer style fuel pump on this motor. This style is getting a bit hard to find and descriptions on eBay are sometimes vague. I can fabricate a bracket if the newer style will work.

    I recently changed the VRO pump on my 1994 evinrude 120 looper. I installed a new dual pump sold by Promarine and there is a ticking noise coming from the pump. I’m curious if that is a common occurrence?

    1996 Evinrude 90 hp SPL. No VRO on this model. The engine is not running and I am getting a faint sound coming from the warning horn with ignition on. It just started doing it today. If I ground the heat wire to the head the sound gets much louder. Also if I ground the horn at the ignition...
