I have a 1973 Johnson 50hp (50ESL73R) that has an issue with power. When I punch it, it balks and stalls (trying to pull the kids tubing). Then it finally stalled and when I went to start it, a buzzer went off in the controller (never heard that before). It hasn't worked right this year. It was rebuilt last year - worked fine, properly winterized.

Re: Powerband problem

Verify source of warning buzzer before using. I believe '73 only had overheat. Did rebuild include new water pump in lower end?

Re: Powerband problem

The buzzer is in the controller. I can't imagine that there is more than one (is that what you mean by the source) ?<br /><br />No angus it didn't. The water pump looked good so we didn't replace. I've since heard about the overhead issue. Maybe winter was hard on the water pump.<br /><br />I'm going to drop the leg tomorrow and see what's up. If it's not that - any other ideas ?

Re: Powerband problem

Always always always replace the water pump when rebuilding the engine. Its extremely important that a "tight" motor runs at the proper temp.<br /><br />Just like the carb rebuild -- its part of rebuilding/replacing the powerhead.
