Title: Kit and parts for Marine QJet
Post by: dchapma1 on June 26, 2012, 05:44:48 AM

Hi Cliff,

I have used your parts and book to do my 1970 Judge and had such great results I now want to do my boat carb.  It is essentially a Chevy 350 (Mercruiser) with a 4MV carb on it.  I get heavy BOG on acceleration.  I have a standard carb kit with the gaskets, can you recommend additional parts, primary pump, tubes, etc that I should use?

Top RPM is 4600 and being a boat it has a low end torque type of cam. Other than that it is a stock 350.

Thanks Much,

Don

Like our automotive kits, our Marine kits are complete with the upgraded components for this new fuel.  They come with a complete Marine accl pump assembly with springs/retainer, high flow Viton needle/seat assembly, float, high flow Marine filter w/spring, gaskets, small parts.  You can purchase the needle/seat assembly and complete Marine accl pump assemblies separately if desired....thanks....Cliff

That sounds great and I'd like to purchase the marine kit. Let me check the parts page and if I have any questions I'll get back to you.

Don,

Any suggestions on jetting changes?

Best to order carb kits by phone.

Most Marine q-jets will NOT require recalibration, as they were not emission calibrated, and pretty generous for fuel delivery right to start with.....Cliff
