This actually removes the holes from equation because they are already out of the water when running. This provides more of a clean water pickup for the engine in these cases.
@@MacJank7 You're plugging factory tested holes ! Million of dollars of research, for you fools plugging 4 holes. Instead of mounting engine properly these lower won't be blowing up. Talk about ignorance!!
@@chunkyfather29 no, you’re ignorant. Every boat and application is different. My 350 is constantly taking in air from these holes resulting in water pressure loss.
Excellent info will work on that asap, already buy it!
Does this void the warranty?
I have the plugs and I’m still pulling 21 lbs of water pressure.

$22 for shipping 8 tiny screws and a tap. Not counting the corrosion those dissimilar metals will cause.
Less water not good !
Air does not work well in a water pump either. Why make an ignorant comment? Plenty of folks are plugging holes in Mercs with no negative issues.

Less water is what’s needed for some set ups. Too much water psi and you’ll blow your lower unit seals.
