Flushing port

Hi,

I have a 2020 60HO. The flushing port has a black plastic cap/nut on it. This cap has a small 1/8" hole in it. What is the purpose of this cap if it has a hole in it? In order to flush the motor you must remove this cap and screw in a garden hose. The problem is you really need to first screw in a short piece of hose so that you can thread it into the port. This adds a an extra step. Is there any reason I couldn't replace the OEM cap/nut with a plastic quick connect? The hole in the quick connect is larger than the stock piece. Any down side to this?

Thanks

Re: Flushing port

A year or two ago many of the ETEC models incorporated a new fuel pump design which requires the water outlet restrictor to provide proper fuel cooling.
You can either flush the engine by running on flush muffs or by temporarily removing the water outlet restrictor.

Thank you.

So the fact that the hole in the quick connect is larger would cause a problem?

Yes.

 

 

What can get confusing is that with the earlier models, without the newer VSA, needed a 3/8" dia. opening to allow enough water flow through the fuel cooler (VSA) and the EMM. If the older ones were restricted, the EMM would overheat  at heigher speeds.
