I am looking to put a drive shower on my Bravo 1 and wonder which is best. I have noticed that some are claiming not to have to drill into the drive, which is great. However, I am most interested in which one is the best at cooling the drive and holding up over time. Fresh water boat.

Consider plumbing a line directly from your sea strainer thru the transom to the top of you drives. That is how most of the race boats do it so you don't loose any performance due to cavitation.

Thanks for the thought, I'll look into it.

this is the one you want the pick ups are in the prop wash and do not affect performance

Does it works at higher speeds then???

Go with a separate transom pick up or plumb it from the sea strainer as Wahoo suggested! Get as much water flowing as possible and use one of the "lid"-type showers.
