Some do, some don't. It's a hole in the boat that has the ability to fail. Whatever lets you sleep.
If you have a scoop type through hull fitting it is a good idea to close it when sailing so you do not hydro-lock the motor by forcing water into the engine through the exhaust system when under sail for an extended period of time.

I was skeptical but now I am confused! I cleaned the gasket and all rested up and I have no leak. Everything works as before. Thank you for the advice. Small additional question: Close up the water inlet valve of the engine whenever you stop the engine?:

Thanks for the reminder, I will add it to my punchlist.

I learned the hard way this weekend after I finally splashed Shakti about why I was should not have forgotten to drill the shaft and set the set screw for the new motor coupling.

That and a couple hours stuck in the mud on my maiden voyage to the slip was an adventure.

Think of it as a power rinse for the engine compartment...

I had a nylon vented loop on my O'day 35 with an M25. I broke it, and have since installed a Forespar Marelon loop, but removed the duckbill, and retro-fitted the 3' long tube that goes well above the water line, and was originally on the nylon loop. I keep the duckbill - just in case.

Re: anti siphon valve universal m25

I've removed everything and rest enn assuring me that the air or water circulating well. I'm a little skeptical that a cleaning pipes and valve gives a good result. I will test this weekend. Thank you again!

Sounds like we agree Stu. Just a question of terminology.
