Where do I start? I discovered last season that my voltage regulator had burnt out and this was causing by battery problems and not the kids playing on the boat leaving lights on.
Now other than the battery going flat I had no other problems with the engine.
Since I replaced the voltage regulator, impeller, engine oil and gear oil I've had this 3 beep alarm every 4 minutes while the engine is in gear. No alarm with the engine running in neutral. Also the engine runs fine while the alarm sounds, no limp mode and not running rough. I've check oil levels and impeller with no issues.
And ideas what it could be?
