I think that i get some air at hi speed by the top hole on my Bravo 1 drive because my engine stay at 130F at cruise and raise at 160 at full speed.

I know some guys block some water pickup top hole,
So how many hole should i need to block to solve this isue?

Is it a DWP drive??? or just side pick ups????

Side pick ups

Mr Gadgets

I used to block off the two top holes on my sidewater pickup, never had any issues with it. Always ran 145-150 on my gauge..

The top 3 holes have been blocked off on my Bravos. I have low water pick ups in the nose cone as well as the high water pick ups on the side though.
