Do the prices listed include the core charge? So if the core is ok then for planning, a person can deduct that amount for the powerhead?

Hello, Some of these items do not have a core charge and some do. It will come down to which are you planning on buying. But the core charge will be deducted as soon as we receive the core. Thank you -- Andrés Nasser Crowley Marine 1-800-580-0720
