Looking for 2 sets of the these tall Gil Bravo Risers for HP 500. These are the second design. Will only consider fresh water, in clean condition. No Junk please. Pm or text 816,eight zero 4, six three 11.

Still looking.. What about the Hardin Marine risers, part number
620-32330 ??

I have 2 sets of them. Mine are for use with Captains Call. Also have the Captains Call available.

Text or post pics. Not sure about the CC option. Getting reversion on the stock risers already, and that is on the test stand. That is why I am looking for the HP500 2nd versions like the ones pictured.

Those look interesting. What were they installed on? I cannot quite figure out how they are assembled. What part number is engraved on the side of the mounting flange?

Corsa Captain's Call. Factory install on 1999 HP 500's. One end connects to the end of the pictured riser and passes straight through to the transom tip assembly with the other pipe to the Y Pipe when in their closed position.
I have the risers, Corsa Captain's Call, and Y Pipes. At the moment not sure about the numbers.

Did you ever find the etched number on the base of the risers? What are you looking to get for the whole setup? BTW, hope you are safe and avoided any of the major storms last night. You can Txt me @ 816-8 Zero 4- 631 One

844418-99-6 on the one I just looked at. Guessing they are all the same. When you say whole setup are you talking risers, Corsa Captians Call, and the Y pipes that are needed to go from the bottom opening of the Corsa to the transom assembly so exhaust can exit through the prop?

Still trying to track that number down. Yes everything, except the lower Y pipe, unless that is some custom pipe that is different than the stock Mercruiser Y pipe. Were these on a Bravo drive setup
