Force 50 HP 507x5a

Repair Difficulty: Hard
Repair Time: More than 4 hours

Experience was good but paying $5 for shipping on a 1/8 ounce drive shaft pin is a bit ridiculous.

Problem fixed: Drained lower unit fluid after purchase. Found water and lube mixed and salt corrosion from prior owner. All seals were shot.

Complete lower unit gear seal replacement and water pump repairs/replacement. Used your drawing diagrams to identify seals and other replacement parts available. Placed order and proceeded to remove all old seals, clean bearings and use salt remover wash to aid corrosion removal. Pressure testing lower gear box soon to see if my work was effective at sealing lower unit back to specs.
