What to do if my Volvo Penta 5.7GL-A/B Engine cranks but won't start?
- A
  andersonsusanAug 8, 2025
  If your Volvo Penta Engine cranks but refuses to start, the issue could be due to several reasons. First, check if there's fuel in the tank or if the gasoline shutoff valve is closed; fill the tank or open the valve, and inspect the fuel supply for water. Water in the fuel supply or old gasoline can also prevent starting; in this case, drain the fuel tank and flush it with fresh gasoline, and change the fuel filters. Also, make sure the emergency stop switch lanyard is reinstalled.

Why is my Volvo Penta Engine losing performance?
- D
  Diane VargasAug 19, 2025
  Loss of engine performance in your Volvo Penta engine can stem from several factors. Check if the boat is overloaded and redistribute or reduce the load. Ensure the bilge is drained according to regulations. A dirty boat hull can also cause performance issues, so clean it. Finally, using the incorrect fuel octane can lead to performance loss; use the proper fuel.
