I have a 98 2 stroke 15hp that needs a lower unit. I found a guy with a 03 4 stroke 15 lower for $250. The part numbers are close my 98 is 63V-45300-00-4D, his lower is 63V-45300-03-4D. I compared the two and they look the same but didn't want to purchase without confirming with someone. Can anyone help me?

he had it from a parts motor he bought, its clean and shfits by hand and spins smoothly. I just thought $250 was good because the prices on ebay are 300-600. If anyone has one that would fit for less i would buy it? -
TT (AKA SeaStar) won't/can/t answer your question as he doesn't know the answer. He's a *****(stirs up crap).Originally posted by pbois View Post
Wait for someone who knows to answer your question, (will it fit) and NOT go off on a tangent..
Just ignore him, he'll go away..Scott

Anyone know if the 4strk lower will work?Comment

IDK, but someone will chime in (with experiance) and get you going.
PM Boscoe if no one responds. He checks his PM's and would likely know.
Rodbolt too but he doesn't check PM's..Scott

the 3 is the design change code, basically meaning it is a super-cession to the old part.
I believe it will work, but I'm a bit of a noob so might pay to get Rodbolt's or Boscoes inputLast edited by greasyshaft; 06-03-2015, 06:32 AM.Comment

never tried it.
however for not much more than 250 you could fix your case.
why do you think you need a new case??Comment

when deciphering the Yamaha part number.
the first 3 digits/alphas indicate the FIRST model that it was used on.
the next 5 indicate the part type.
the next two indicate engineering changes, last two indicate paint codes and such.Comment

Just realized my silly little program was spitting out rubbish (I sort of new it would be pointless but what the heck) so deleted post LOL

The complete model identities are needed. There is a short shaft and a long shaft lower unit for each motor type. I am presuming that we are talking about a short shaft model but if so, the part numbers you mention don't agree with what the parts catalog is showing.Originally posted by pbois View Post
The Yam parts book shows a 1998 15MSHV as using a 63V-45300-02-4D.
The 2003 F15MSHB is shown as using a 66M-45300-01-4D.

***, now that a lot of info, lol. I am trying to get his exact model # and will post it. Thank you very much for helping out. The previous owner of my engine struck something with the lower creating a hole in the lower and it filled with salt water. Then they let the motor sit for a couple of years. I was thinking about trying to rebuild it but the inside is a full of rusted parts.Comment

My engine is 15MSHW, his is F15MSHBComment

If you have access to the F15 lower unit I would trial fit it to your motor. It may very well work and work just fine. Unfortunately, I don't have access to any Yamaha data that says yea or nay definitively.
If the bolt pattern in the same, if the shift shaft is the same length, if the drive shaft is the same length then the odds are good that it will work.
One thing you can do if you have some time on your hands is to open both parts catalogs. The one for your motor and the one for the F15. You can compare every part used in one lower unit with the parts that are used in the other lower unit. I did a quick look see and the majority of the parts are one and the same.
Just keep in mind if and when repairs may be needed to the different lower unit you will use the parts catalog for it to source your parts.
Let us know what you decide to do.Comment

Well I bought the lower unit and it bolted up fine. Engine ran and shifted smoothly and cooled without issue. I just have to test run it on the boat to be sure it will work properly. Thanks for the help and I will post my end resultsComment
