Q:
I have a 2000 Searay 5.0 Mercruser alpha 1 Which impeller is right?
A:
You will need 18-3147 for the kit. 18-3056 is the correct impeller.


Q:
In reading some of the reviews I noticed that several comments were made in regards to the water pump base size being incorrect. When ordering how do we make sure I receive the correct base. It seems that either will mount but if wrong will fail. I am wanting a complete water pump for alpha 1 gen. 2 s#0D627752?
A:
This is not correct for your outdrive. 18-3147 is the correct kit. You do not really have a base necessarily. You have the housing and then a face plate to mount it to. The 18-3147 is for sure the correct kit for your outdrive though.


Q:
I have a alpha 1 out drive made in 1988 wich kit do i buy?
A:
This is not the right kit. Alpha 1 Gen II motors began in 1991. MR/Alpha outdrives were from 83-90. So 18-3320 is the correct kit for your outdrive: http://www.iboats.com/Water-Pump-Kit-18-3320-Sierra/dm/view_id.187582


Q:
I have an alpha I drive serial?
A:
Part 18330 will work for an MR/ALPHA 1. Part 18-3147 will for for an ALPHA 1-Generation ll.


Q:
My serial number is 0d363567, which kit do I need?
A:
You would need the 18-3316, which would come with the base.


Q:
I have a metal flush screw on the gear housing and i ordered a 18-3317 water pump kit. It don't have the thread for the screw. what kit do I need?
A:
We cannot match it up this way. We will need to know the engine application to even begin to confirm with Sierra. Let us know if you can provide that.


Q:
What is the impeller part number (just impeller)?
A:
Unfortunately, we are unable to look up parts individually, but if you have your specs of your engine, you can call in and we can provide the number for just the impeller. The phone number to call is located at the top of the screen.


Q:
Is this the parts for 0C832966?
A:
No, the one you would need is the 18-3317.
