I’ll have to check with prop shop for actually degrees on each side. GPS speed 30 mph. From what I read that’s all they do with v drives

You running v drives or out drives?

Well pulled two degrees pitch out of the port prop and now I’m up and running 5k rpms as I should. The starboard now needs some adjustment to catch up but it’s much closer than it has ever been.

I will tell you the engine that runs great does steam more than the port motor that would indicate a hotter exhaust temp.

These engines in this application run closed cooling systems so the actual engine temps stay the same around 160-165. Haven’t checked the drive to see if it’s getting hotter though. Also could possibly check manifolds them shelves.

Well I just made a phone call to the prop shop and found out that they didnt drop the pitch on the cr prop so that could very well be my problem. Because the props aren’t stock they are 4 blade Michigan props which it would make sense why it would have done this before I bought it because when...

Yes that’s rolling wide open under load. Now during acceleration it’s ranging but once you hit wide open and it stabilizes they both ready 24 btdc

I follow you but why does the other motor read the same timing and perform great? It doesn’t always read 24 that’s just at wide open throttle.

It has to be something that the computer is seeing that is affecting the power and rpm. I just can’t pinpoint it

The port engine is a quicksilver reman long block. It has less than 20 hours on it and is doing the exact same thing the old engine was doing to the tee.

I have swapped pcms it does the same thing.

Both motors have new oem coils and ignition modules. I have installed a brand new cam sensor that is in the distributor. I haven’t swapped the distributor it’s self. I also believe it’s a ignition timing issue not allowing it to give it full power and rpm. I swapped crank sensors between motors...

Both motors show 100 percent power on guardian system as well. The only codes it sets are ghost codes for stuff it doesn’t have.

So believe it or not when we had the factory scan tool hooked up the starboard motor was reading 87 percent on linear pid and port the one with the issue was reading 90 percent and not exceeding 4400 rpms. So the tech got down in the engine compartment while running and pushed cable all the way...
