Default Big block I/O Bravo flushing kit...?

I have searched but I could not find definitive solution for a safe/effective way to flush the motors and drives with a garden hose. I assumed that there would be a tried and true kit/package to safely flush with fresh water/anti salt solution after each/every salt water trip/use.
Thanks, I have big block Mercruisers with Bravo drives.
Links to product/vendor would be appreciated.
Thanks, Tom

Perko makes a flush kit, but it’s plastic and known to break. You can buy the kit but instead of using their valve replace it with a stainless 1-1/4”x5/8” tee instead. It’s all nothing more than a tee right before the water pump and a garden hose fitting wherever you choose to place it. Do a search on Perko flush kit and that should answer your questions.

x2 what Rooster posted above. Replaced two broken Perko flush valves with these. Had to buy additional barbed male adapters and everything works perfectly.

Turn a couple valves to flush as it's not as "automatic" as the Perko's, but I'd NEVER want a cheap, plastic spring loaded check valve on my seawater intake. You're just asking for a catastrophic failure.

Great answers...
I had seen the Perko and read about the lack of robustness. So, If I get the Perko, replace the valves with Webstone brass or stainless steel and locate it according to the Perko instructions...it will flush motor and drive without damaging the impellers?
Thanks

I use the old school earmuffs on the foot with a short bungee to keep it in place. I also use the Salt Terminator after every trip to salt or brackish. There is a lot of debate on its viability, but I have no doubt after seeing the inside of my last motor after 300 hours. It looks like it was in a car. If you have dwp, a small piece of masking tape will block the nose cone holes. Make sure you get up to temp before you call it done. Happy boating

I’ve posted about this way in the past on this page.

Mercury had a quick connect kit for the garden hose side, and I bought Tees from CP Performance.

Don’t use use the Perko for an offshore boat application.

I never had an issue using muffs on bravo drive. I installed a sea strainer 2 years ago and installed a flush kit directly into the strainer. Definitely works better this way.
