The fishing boat my client owns has a large transom that makes lifting the 40HP engine a difficult task. After getting a quote for $2200 + fitting for a motor lift, he asked if I could come up with a solution.
A simple lever wasn’t going to meet the needs as the suitable positions for a lever still meant leaning far over the transom. A solution that was accepted was to build a lever from a 40mm slab of HDPE my client had recovered from the beach, adding a pulley and a rope gave a 2:1 advantage and allows the operator to lift the engine from the safety of the cockpit.
