get the carburetor number from the port side of the carb and you can cross-reference with a new or rebuilt carb that's an exact match. should be a 4bbl rochester, not sure of the flow capacity, you will be able to find that out with the engine serial number or the number stamped on the carb.

that's a very nice boat by the way.

Ayuh,.... Post a picture of the motor, not the darn boat,... the intake is even Better...

A '93 shoulda been sportin' the Merc/ Weber, in 750 cfms...

The Edlebrock Performer is a Carbon Copy of the Merc carb,... the parts even interchange,...

Again, the BBC, wants the 750 cfm model...

I have a '93 7.4l with a Bravo 1 and I have the factory Weber 4-barrel. However, I'm unsure of the rated CFM's on it but I would assume 650 to 750. But as stated above, the Edelbrock carburetors are the same carburetors. I personally am putting the 1410 on mine during the winter.

Webber, Carter, Edlebrock are all basically the same. Just make sure you put on a marine carb, not an automotive / hot rod one. The big determining factor is if the manifold is a spreadbore design (Rochester Quadrabog) or square design (the above mentioned carbs). Most shy away from Holleys on the boats for various reasons.

My '92 is a Webber and from what I read, is a 750 cfm. If you can, get an electric choke model, they seem to work better / last longer than the thermal spring types (though I haven't had many problems with mine).

Ayuh,.... The BBCs got the 750 cfm version, 'n the 4.3l, 'n 5.7l got the 650 cfm versions....

Some of the hybrid 350s, 383s also got the 750 cfm versions...
