Ok, I am stumped with this one folks. My yamaha C115tlrx gets on plane and after a couple of minutes the motor seems to bog down and loose power. Here is why I am stumped. Compression is good, carbs are recently rebuild, fuel lines from tank to motor are brand new marine lines, brand new...
Hey all. I have a 1994 Yam 115 2 stroke C115TLRX is what I believe to be the code, its a bit faded. Anyways, I replaced throttle and **** cables which were rusted thru and thru. Took carbs apart, and seemed to be pretty clean, sprayed carb cleaner, and then ran seafoam through the engine for...
So i got this 1986 Yamaha 200hp on a Wellcraft 230 Sportsman as part of a trade. I didn't know what condition the motor was except it had good compression, and was not missing anything. I finally got it to start today after replacing plugs, water separator, and fuel lines and primer bulb with...
Hello.
Can anyone point me to a video or webpage, or anything that may be helpful in guiding me to rebuild the carbs on my 86 Yam 200hp? I recently got this engine not running but it turns and has good compression. I figured i would start with carbs since they seem sticky. Also going to check...
So, I took my boat out this past Thursday to the Skyway Bridge fishing, ran great. Went later to the beach for a swim with the kids, ran great. Time to head to the dock, started making a rattling noise so i backed off the throttle and it went away. Tried to throttle up and same noise came back...
So i had an issues with the motor overheating. Today I took apart the head covers and water jackets, and thermostat housings. There was a good amount of debris and salt deposits in the the water passages, so i cleaned them all up best I could. I had planned to do this the day before so I ordered...
Need help figuring out where these wires belong and what they are. Some come out of the control box, some from he harness at the motor not the harness from the box, the harness a the motor itself.
Does anyone one know if a water pressure gauge can be installed directly to the head via fitting on a "87 johnson 120, or do I have to go the telltale route? Thanks.
Ok, bear with me folks bit of a story to write here. So I had posted about my motor temp alarm going off. Now, I replaced the water pump and both thermostats. I went out yesterday, and to make a long story short, had to get towed in by the coast guard. After a few minutes of running I stopped at...
Hi everyone. So I went on the water 2 days ago, and had the warning on the control box go off twice. Both times I was running about 5k rpms, and after around 15 mins of running. I backed down to idle for around 20 secs and the alarm would go off, then i could continue. Ran fine without alarms...
Hi all. I am trying to replace the water pump on my 87' J120. Model J120TLCUR. I can get all the bolts off, including the ones under the trim tab thingy by the prop. Something is not letting the lower unit release, like the shift rod. I know I am missing a step but can figure out what, and I...
Hi all. I have an 87 Johnson 120, model J120TLCUR and was wondering: What should be the rpm at wot in this motor? Ever since I got it I have not ran it past 4500 rpm due to not knowing what the max safe rpm are for this specific motor. Also, I would like to know if anyone has any tips to safely...
I just bought a 20' wellcraft with 1980 (i assume) Johnson 120VRO, will post serial later. It looks to have many new parts (starter, coils, and the heads look to be in pretty good shape)
Tried in the river before buying, ran great at about 4k rpm for about 5 minutes. Not a peep. Every thing...
I was out on the boat today, beautiful day. Cruised on the Hillsborough River in Tampa, Fl for about 2 hours, at mostly idle speeds. Upon returning, i kicked reverse in to get close to another boat. Boat would not start after that. It would try to turn but it had no juice. Batteries were dead. I...
