Thought all 2.5's were oval port, what years and models were bridged ? Had early 2.5 Carb it was oval. Dave
There were a few "Z-port" 2.5's that has a diagonal bridge in the exhaust port.
What prop were you running on your STV with the BP?
a bridgeport omc racing engine as all OMC custom block racing engines areQuote:

The worlds FASTEST OUTBOARD MOTOR is an EVINRUDE V8. Running at close to 10000rpm with a overdrive gearcase this incredible motor powered a 20' 3 point hydroplane to a 2 way average of 176.556mph. During testing it easily exceeded 190mph but was damaged after hitting an object in the water.Dec 26, 2010

There were many 2-cycles built using a "bridged exhaust port" . I quoted the Hodaka manual . The fast OMC's I've seen had this modification done as well as the little oil hole .. ;)
The OMC's .. yea ~ no they weren't done with a small wetstone .. They were done with a big ... :)
The Merc Bridgeports .. are there any left .. ?
The brief history that I know about them is , that they were 3 3/8ths" bore.
They came from the factory with :
5 cylinders that were plated with industrial chrome.
1 cylinder that had a random steel sleeve ... sometimes more .. :D
Now ifin the block didn't have the little clearance deal done "before" it was plated, chances are pretty good that it became a member of the "soon to be extinct" club .. :eek: :p :D
I still have a 2.4 Bridgeport, original plating and no cracked bridges. Pistons have a relief machined in them, the original Mahle pistons were like that, as the Merc replacement Wiseco's. Steel bore motor your suggestion would be a smart move.Quote:

Power .. Your boy Bobby Worthead has done more to **** block water based record attempts than any left~wing group of people could ever hope for .. :(
You happen to know what size jets they had in "the hammer" .. ?
Long , high internal capacity , single end fed , spray bar systems have poor distribution characteristics .
Why wasn't the boat ever run again .. who has the motor ?
I got a canole' that says they hurt it .. kept it quiet .. locked the books , and quit :p

So why did merc stop making BP engines?
Behind the liner porting on the 2.5 was better, no more finicky bridge, more power, less stuck pistons...Quote:
