Ballast pump impellers?

[2in2out]

The 2 under the trans cover went bad on my 2019 at 80 hours.

THIS!!! 72.5 hrs on the boat. I’m having the 75 hr service done and winterization, so I thought it would be good peace of mind having them replaced and having spares. I know it’s easy, but if the access points only have to be opened once, less chance for inadvertent damage.

I just was curious if I provide the impellers if it’s worth the savings, or should I just let the service center charge me for them.

So do the Supras use the same ballast impeller as the Moombas then?

Yes sir. Skiers uses Jabsco puppy pumps and the green impellers are the newest replacement option.

The two center ones were very easy to swap out on my 2018 SL.
The transmission hatch needed to come out to get to 2 of the back pumps. There were 4 screws on the transmission hatch floor and two against the back seating area.
The last two pumps were located between the back seats and the lockers. Not impossible to get to, but took a little time.

I would ask how much labor they are charging before they start the job. I'm sure the $30 green impellers will be more at the dealer. If you boat is already at the dealer, it always easier to flag a check, but it's $$.

I was talking to a local guy over the wkend about winterizing. He was not comfortable and nervous about doing it right. My comment was take it to a deal for your peace of mind.

I used Wakemakers and had the part number: Jabsco part #:6303-0107
If you google the part number, Wakemakers and Amazon find the same listing.

This is the exact same impeller that comes in every Jabsco Ballast Puppy pump from the factory regardless of the boat brand. 6303-0007-P and 6303-0107 are the same part number, the P just denotes that this is an individual pack versus a bulk pack option

A dealer told me they don't winterize the ballast system on a 2021 Supra SA450 that I ordered, they only run them to empty the system. This seems wrong to me, what has been your experience? Is there a service manual that outlines this in detail. Does anyone know of youtube video or have pics of where all these pumps are at and how to winterize them and/or change the impellers on this boat or boat with same design. I prefer to do all basic service myself and looking for any information on this boat.
