They had an exploded diagram of the engine on my boat which was very helpful and selecting the parts needed to make the proper repair.

Problem fixed: Lower unit leaking oil from output shaft

Drain the gear oil in lower unit, removed the prop and the two bolts holding the gear assembly housing. Pulled gear assembly out and replaced the needed o-rings and seals. Reassembled product in reverse of taking it apart, added the accurate 90 weight Mercury gear oil.

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.

I have found everything I need at crowleys and the prices are excellent

Timely delivery. Unfortunately I ordered the incorrect item. The return was amazing. Two days after I mailed it back a credit showed up on my credit card.

Actually have not done it yet. Would be nice if instruction or a link to instructions were included in package.

Ordered my parts for next day delivery, parts arrived complete the next day. During the part replacement, it was discovered that one part was incorrect. The store was notified and they shipped out the replacement right away and it arrived the next day. Overall, a very good experience and an excellent recovery by Crowley.
