I personally like to run the 2.5 plate if running a 2.5 PH.
I also like to match the exhaust port to block ports.....but I trust tlwjkw he knows his z*** and has done plenty of testing so if he says it works I'm sure it does!
You can use a 2.5 200 for the 2.5 225PM just open exhaust to match, done plenty or as Tommy stated run the smaller ports......MPO!

ya right Tux.. always best ta run matchin' stuff.. wasn't so much as experimentin' jus 'cause, it was back then sometimes ya had ta do with whats "on hand" and hope for tha best if ya wanted ta go to tha water....

Tommy on doing what ever it takes to get wet....

I also find that the 2.5 plate cools better, not sure if it's just me......

Hands down using good and correct gaskets is a must!

pretty much... thanks bud.

Sorry to hear of your loss Tommy.

I had to put a slight bevel on a 2.4 1piece plate to run a 2.5. The bottom cap assembly would contact with the plate and not allow the ph to sit down all the way. A bit of beveling of the driveshaft hole let the bottom seal fit into the plate and all was good.
That said I'm not sure what 2.4 plate it was. Mike

Would using this tuner solve any/all problems with fit-up ? https://bobsmachine.com/product/mercury-exhaust-tuner/

NO!! There was a 200 & 225 2.5L promax. The 3 L Pro max adapter plate will not work at all. Two completely different animals.

berdes, X2 on Fuller!
The Bob's tuner works pretty well! Currently setting up 2- 2.5 motors with them now.

Just to be clear!
1Stream is correct the 3.0 300PM will not fit on anything 2.5! They made 150/200/225 PM's most of us are responding thinking since you mentioned a 2.4 mid you were using a 2.5 PM.
