    1998 Yamaha F50TLRW Water Leaking From Under Carbs?

    I have a 1998 Yamaha F50TLRW and I crank it up every two or thre weeks to keep the carbs in shape. Today I cranked it up with the muffs on and saw water leaking from under the carbs? I checked the oil and it is not milky so I breathed a little better. The dealer just did a carb job on it...

    I have a 1998 Yamaha F50TLRW and the Lower Unit got very hot after idling only 5 minutes with the muffs on? I've never noticed this before but when I put my hand on the lower unit to take off the muffs I noticed it was very warm to the touch. You would not want to keep your hand on it for very...

    1998 Yamaha F50TLRW Knocking after Warmup?

    I have a 1998 Yamaha F50TLRW that starts knocking after it warms up? It sounds like a lifter knocking. It only has about 150 hours on it. I use Yamaha Ring Free in it on a regular basis. I use 1 oz. per 10 gals. I bought it used and the owner said it only had about 10 hours on it. I did a...

    F50TLRW Carb Sync Question??

    I bought a boat from a man that had a carb job done on the engine, but they were not sync'd. It is a 1998 year model. He was in the Marine Corps and was gone for a while and he left gas in the carbs. The mechanic said he didn't have the gauges and if he wanted it sync'd to take it to the...

    How do I hook up a Dwell/Tach to F50TRLW??

    How do I hook up a Dwell/Tach to my 1998 F50TRLW?? The meter has a black and green lead. I know the black goes to ground, but not sure about the green lead. I'm thinking it goes to the negative side of the coil. My Clymer shows the ignition coil and the wire that is the ground for the coil...

    Carb Adjustment '98 Yamaha 50 HP 4 Stroke F50TLRW??

    Will a shop manual for a '98 Yamaha F50TLRW tell me how to adjust the idle? The previous owner had let the engine set and it varnished up the carbs. He said he had the carbs worked on, but the idle is not right. When I go fishing, I have to increase the idle in order to get the engine...

    Yamaha F50TLRW No Power Question??

    I have a 1998 Yamaha F50TLRW that idles great but will not run faster that 1/4 throttle under a load. Here are some things I did and found. I took some bad advise and stored it without running the gas out of carbs. I was told if it had the Yamaha Ring Free additive in it you did not need to...
