Little Help! RAW water Impeller?

[covertcombatant]

I have a 1988 Supra TS6M that I just purchased. It has the 351W in it and I'm looking for the RAW water impeller. Skidim has 2 and I'm just curious on which one I will need. I will attach a photo of the pump. It looks like i need the second one on their website with the gasket and not the o-ring but im just not sure.
Also what temperature should the boat maintain at normal operating temps? Thanks for the help.

I've used the 712 impeller from Skidim.
I take it out when I winterize and look at it. Last couple years it's looked good so I put it back in with a new O-ring and carry an extra on board.
Don't forget to mark which way is up on the water pump or you can put it back together upside-down and pump water out of the engine instead of in.
My temp runs 160-180.
Also, the guys at Skidim are super helpful. Don't hesitate to give them a call.

Get the run dry silicone ones. Much better and you'll never have to worry about it again. I get mine on Amazon

Thanks Scott and Cusefan,
Cusefan do you have a link for the silicone one? Thanks

That pump I believe has the o ring. You can open it up to make sure. I keep the old impeller on board just in case needed on the water.

Like he said guys at skidim are great and friendly. Vince used to own a supra and can tell you anything you need to know about your boat.
