I have a problem with rpm above 3800.
When running in neutral the engine can take full throttle and hit rev limit, in gear it will not go higher than 3800.
This winther I had the engine out for overhauling, all bearings, pistion, pistion rings, oilfilter, fuel filter, hamonicdamper*and*gaskets replaced, engine bored to +.64 oversize.
Ignition set at 8*BTDC, idel rpm 650-700, engine runs normal up to 3400 rpm in gear,*with normal fuel consumption.*
The engine starts and runs normal hot and cold, before overhauling the engine was running @ 4600 rpm*taking the boat to 48 mph (gps) now I can take it to 3800 rpm 37 mph (gps).
Have I missed something when assamble the engine ?*sensors, cable adjustment*? is there something in the engine control that can be link to*taking the boat into gear and hold the rpm down*?**
Everything on the engine and outdrive is the same.

My boat is a Sea Ray 270 Sundancer.
Engine mercruiser 502 Mag Mpi.*
Outdrive Bravo III.
Prop Signature 24P.
