Drive Shower
 

Why don't i see more people doing this? Seems to me that it would be a whole lot better set up. And how do you plumb it up to do it? Click on the next picture to get a better look at it.http://www.offshoreonly.com/classifi...&f=34080_4.jpg

im having a hard time seeing where the water is coming from for the showers. if its coming out of the engines i would think thats defeating the purpose because the water is already hot.

Could be a "T" fitting coming off the raw water pumps? Must be getting water from somewhere?

Looks like they are water pressure dumps, so the water would be cool, un-circulated. Good way to use the water for something.

I think that it would work a hell of alot better than a drive shower that has a pick up. It is only going to increase water as the rpm's increase. I was hoping that someone would have some pictures of how they did it and what size hose they used.

I wonder if those are pick-up tubes coming out of the stern bottom either side of the bildge plug? They look to be about the right diameter.

I would imagine that those are water pick ups for the motors. I don't see any on the drives, but im no expert.

The Merc dumps have a 3/4 hose coming off them, most people just dump out with a through hull, but you could easily adapt it to come out where those do.

Those are engine pickups, should feed a strainer then through the raw water pump. If you lengthen those slightly you can get about 100 psi water pressure at speed if you want it. (you don't)

Wouldn't this be better than a typical drive shower,or am i missing something.

If you have enough water pressure that you can dump some off, yes. But adding a pickup will kind of defeat the purpose. The one negative with showers is they slow the boat down. I lost about 2 mph when I put the Simreks on my 311. Any protrusion from the hull or cavitation plates on the drives will scrub off speed. So if you can get water without adding another protrusion it is free speed.

A buddy has the same set-up, except that his water dumps out the transom and falls 6-7 inches right onto the top cap. The key is the transom mounted pickups for the engines cooling water.
The drive water pickup water hose on the inside of the transom is routed straight up and right back out the transom. At speed water is forced up the inside of the drive and right back out as drive shower water. My buddies dumps the water, this set-up carries the water through the hose to the top cap.

My Cigarette has water that dumps on top of the drives. It is split off at the exhaust, so it is HOT. I use Halo Max drive showers and they are great. The side walls on the drives are what you need to cool. They are thinner. I have a 1994 38 foot Cigarette TOP GUN that weighs over 13,000lbs when fully loaded. I have twin supercharged 600hp engines on the old style bravo 1 drives with the 1 inch prop shaft. I also have 5 blade Maximus props. I have not had any bravo 1 problems since I bought the boat in 2004. Knock on wood and I think it is because the Halo Max drive shower's have kept the temp down. Also, I don't go more than about 6 miles before I set her back in the water. The freshwater lake is small.

look closely,,,,,there is a crank shaft raw water pump that look like it feeds the showers along with the factory bravo raw pump in its usual place
