Gravity III upgrade
If your adding large bags in the lockers I highly suggest you get one 800 pump for each bag. Once you get over drilling one hole in your boat the next ones easy.
I’ll get pics underneath a little later.
First pic is pump just in front of the v-drive starboard side.
Second pic is the pump on the port side of the v-drive.

As long as you’re doing it, why not use an 1100 or 1200 instead of an 800??? Also, why not increase the hose from 3/4” to 1”??? My original rear drain pumps both burnt out in the last couple years and I put the Rule 1100’s in from Wakemakers. I had to increase the size fuse but otherwise it works really well, even with 3/4” drain hose. I’m hoping to increase my drain hose this year to 1” to decrease drain time even further.

I'd like to know what your fill and drain times are. Keeping the slow pumps and keeping the 3/4 line would be painful with 1100 rears and 1180 gravity bag... I'm well under 10 minutes with the T1200s and the larger hose.

Under 10 minutes is really good. The 800s do a pretty good job. 14 minutes to fill 2 1100s and a 1380. I have the fat sacs that have a 3/4 inlet. I figured this would choke off the 1200 pumps and you wouldn’t get the full capability out of the pump. For the money I spent I am satisfied.
