When I take off, my left engine only hits 5000 rpm's. About 3/4 out of the hole it jumps up to 7000. My right engine hits 7000 right out of the hole. Any ideas why this is happening? It's costing me power when pulling.

Thanks!

Cavitation/aeration is happening at the pump on this engine. Check the impeller wear ring, and the drive shaft seal on that side. The driveshaft seal can be seen under the PTO cover in the engine bay.
