Hi. I have a Wellcraft Excel with Volvo Penta 3.0. My engine has a 500 cfm 2BBL carburetor. I want to change my carb to a Holley EFI system. Can buy a EFI 2300 for this project? https://www.holley.com/products/mari.../parts/550-849 Please help me with an answer because my carb is a problem. Start very hard and I don't have idle RPM. My idle RPM is now 1000 RPM. Thank you, BR Marius
