1988 272 sr1 exhaust upgrade
 
Anyone know if gil manifolds will fit in this boat with twin 454's? The space between the two with stock manifolds is pretty tight and the gils are pretty wide. Boat is wrapped for the winter so I can't measure right now.

Any help is appreciated.

Should be no problem. I believe the beam in the 272 is 8'3", the same as the 303. Take a look at the pic in this thread; this is RT930turbo's 303 (my old boat) with 454Mags and Gils:

The beam on the 272 is 8'0". MY 357 with an 8'6" beam has Gill's with dry tails and thay are a tight fit.

The beam on my 1988 311 was 8 feet and I installed Gils with no problem.

I have gills on my '89 311.they fit but are tight.I had to reposistion the ram to lift the hatch

Trs or Bravo ?you can measure the drive centers..,,same thing.If its Bravos with center rise mercs the gills should work but if there tail rise and trs I would look closer at the motor seperation 2c

272 is narrower than a 311, I'm working on a 272 right now, I'll measure between manifolds tommorow...

I looked at the formula website and in the vintage section the 1988 brochure says the 272 is an 8' beam not 8' 3".... like 303 or 311....

I wonder if the engine spacing is the same...

Do you have the Gil manifolds now or thinking of buying? If you don't already have them, look at the Stainless Marine manifolds. I'm sure they will fit. Is your boat Trs or Alpha's behind 330's ? I put SM on my 357, lots of room between the manifolds, but mine is 8'6".

Baja226sport 12-28-2010 12:51 PM

Looking at buying. And used to save some money. A ton of money actually.

I just want to make sure they will fit first....

The boat is Bravo's behind 454 magnums...
