Kieran

My Father in Law has a 45 hp Mariner serial #0A989163, will this fit that model?

Answer:

Hi, Please see link below: https://www.crowleymarine.com/mercury-outboard/parts/275_170.cfm Based on our product guide, the part should fit, but it lacks some clarity because a 1980 Mariner Outboard has different versions. I would suggestion to get a second confirmation through Mercury, or if you can provide further details on the engine to confirm ourselves. Thank you again,

Paul

Is this the correct water pump kit for my USA made 1994 (maybe 1995) 40 hp 4 cyl 2-stroke Merc? Serial number is OG151097. Also, if I order this kit do I also need to order any gaskets or seals (replacements for those I may have to go through to get to the water pump)? And, do you know the model number of this outboard?

First time user of the Crowley Marine website ordering process and have to say this group is bang on with getting parts out the door and delivered to customers. Ordered my parts and they were enroute that afternoon and in my hands within two days. Best part to this all is the email tracking and updates that they provide. Placing my second order this week!

So good. These guys handled the COVID 19 supply chain disruption so well. They communicated and made the effort. Owning an old boat they will get all my repeat business, of which there will be plenty!

Problem fixed: Leaky lower unit

Went to pull lower unit and found that the drive shaft was stuck in the fly wheel. Had to remove OB from the boat and turn it upside down, suspending it from the lower unit. Using a grease dissolver and some wooden wedges I was able break the drive shaft loose. After that it was just putting everything back together. Just a side note, I never have worked on an OB before, but I sure learned from the experience.

I was trying to buy a water pump kit for my 1984 Mariner 60 horse outboard and was having a difficult time. Andres took control of the situation, found the right part and I'm happy to report that the new water pump is installed and I am ready to take our boat to the lake for a test run. Thank you again Andres!

Problem fixed: Broken upper shock mounts, replaced impeller while having motor apart!

The two upper motor mounts and seals were blown out. The water pump was seeming to act sporadic also. I went to local repair shop to get estimate only to be told that they would first need to find out if parts were available and they would call with price. After waiting a week with no contact from the shop I got online and found Crowley Marine. The parts were ordered for the mounts and I purchased the water pump repair kit. All were shipped promptly. It wasn’t an easy chore because this motor had some heavy use, and I had never taken an outboard apart before. It now performs fine.
