Re: 25hp nissan outboard problems

If tank's small mesh filter and carb's filter are inmaculate clean, being a 11 year oldie, test with a brand fuel hose, probably air is getting in throught small oring connectors along fuel and engine bogging down at throttle when needs more juice.

Happy Boating

Assuming your model is NSF25A, right? Clean all 3 carbs properly and see what happens.

Re: 25hp nissan outboard problems

What method did you use to clean the carbs? Do you have a vacuum gauge setup to adjust the sync? Grab your Factory service manual to complete the adjustments. If you did not do a thorough cleaning, all 3 will still need that. Then, if you do not sync them properly, you will never get full performance from a multi-carb motor.
