1985 Susuki 65 outboard

[1968 fiberform]

Heres the problem I'm having. Motor starts and idles great, and it revs up with no problems with the warming bar, Goes into gear and I'm able to motor through no wake zones with out a problem, but when I advance to full throttle no matter how fast or slow the motor boggs down and dies or sometimes it will get the boat up on plain. (dies more then on plain). When i can get it on plain it runs just fine but when i back off the throttle it dies.

I have torn the carb apart completly twice using compersed air to blow out cleaner and what ever else, repalced the fuel pump, and the spark plugs. compertion is good 90-100s fresh gas.

I have never had a problem with the motor since I have owned it about 10yr I use the boat all year long so its not sitting for long periods of time a week at the most.

Any help or ideas would be great


Thank You

Welcome to the forum .... did you replace the fuel pump diaphragm?

Thank you. I replace the hole fuel pump with a new one. It also dies when I come off of full throttle. but when it dies it starts right up every time with no problems.
