    Rebuild old mechanical Fuel pump or go for Electric Fuel pump

    A replacement mechanical pump is $50 an SAE J1171 compliant fuel pump is $87, the relay, oil pressure switch and wiring to properly wire it is another $20. then you need to add proper USCG approved fuel plumbing which is another $20. so stick with the mechanical fuel pump.

    if the lift doesnt go high enough to get the leg out of the water when the motor is straight down, either remove the boat from the lift, or the motor from the boat. or the lower can bust like this.
