    Electric fuel pump install.

    I have a ‘90 mercruiser 5.7. Replacing the mechanical fuel pump with a carter electric. Where is the best place to mount the new pump? 21.5ft Mariah. Any need for a prime circuit, as it n a timed circuit to run the pump before cranking. Thanks in advance.

    Alpha prop hub spacer

    1990 Mariah 5.7 Alpha One. When I got my boat earlier this year it didn’t have the brass spacer for the prop. I got one and installed and it slowed the boat down at least 10mph, is this normal?
