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.
https://www.supplyhouse.com/Webstone...ersible-Handle 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 |
Does anyone run muffs on theirs to flush?

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. |
