I have a built 6.5 with 340 hp pump for my boat that has just been assembled. I m trying to dial in the timing on the pump. The spot that the engine builder set it was hard to start So I advanced the pump a little. It started better and ran better. Seems like it needs more advance so advanced a little more. Also runs better. I want to advance a little more but I’m out of adjustment. The builder says to advance the gear that the pump is bolted to one tooth to give me more adjustment. Does this sound correct??
