Marine L-88 Engine w/ Cast Iron Heads - Page 2

I doubt it. I have had 3 marine big blocks and all 3 had 4346 carbs. I have read about others online that also had the 4346. Maybe this is before the Coast Guard required the curved bowl vents on marine applications? I wish is was a 4296 carb with a Fed or March date like the engine [img]<<GRAEMLIN_URL>>/smile.gif[/img]

...How can a marine motor be identified.... from a car motor?
What are the signs? [img]<<GRAEMLIN_URL>>/dunno.gif[/img]

3246 or 4346?

OOOPS, 3246. My mind must have been elsewhere.

So how did the boat scoot across the water? Thats the important question. Could you keep your foot in it? [img]<<GRAEMLIN_URL>>/smile.gif[/img]

I bought the engine out of the boat but never rode in the boat. It was supposed to go 60MPH. Seems pretty fast for on the water.

Many times marine motors have the plugs taken out of the front of the heads for water ports. Also, the exhaust threads are usually studded for the manifolds.

Has anyone ever seen the M/T finned covers with no logo like these ones?
