Throttle Body fuel injection for OMC 4.3L cobra?
 

At first we thought we had a loose wire, but now we think the carb needs a
rebuild, specifically, adjusting the float in the carb.

So; we have a few options, rebuild ourself, have someone rebuild, or buy a
new/rebuilt carb.

That got me thinking -- years ago; I had a mustang and put in "throttle body"
fuel injection which worked nicely & improved response & millage.

Does anyone know of a kit that work in a marine environment?

Also; the points were just replaced last year and already show serious pitting
signs -- has anyone done this:

http://www.michiganmotorz.com/4.3L+D...tribut or+kit

For the price of all the components -- and never having to adjust dwell & points
again; it doesn't sound that bad -- except for getting the old distributor out
w/o moving the engine....

Holley makes a TBI marine unit.

For the distributor, just get a Pertronix breakerless kit - under $100.00.

Got a lead on it? I couldn't find it.

I called them, they didn't have something for the 4.3L cobra -- I asked about
"GM 4.3L" and they weren't "positive" on hte fitment.

I've used petronix on a lot of rigs -- so that was actually my 1st choice.

Thanks

Classic -- when a company's rep doesn't even know their own product line.
(pertronix)

I installed a holly marine unit on my 350 chevy marine engine and had severe
flooding problems, and had to go back to the trusty Carb.Holly told me that
if the battery voltage wasnt at least 11.5 volts that it would flood.After
many arguements with them and threats of taking them to court they refunded
75% of my money back.Expensive for 5 hours of use.Stay with the carb.not
dependable enough...Thats why Crusader is still using Carbs.

Your question was:
I have a holley carb on the boat now; looking for a TBI that would be USCG for
marine use.

THanks
