Default Re: What about this???

I have a 78 i/o CC that was converted to a outboard on a bracket.No matter what speed I run water gushes in the floor drains.When I'm running 30 + Mph it looks like a fountain at a Vegas casino.When the boat is stationary with the plugs out if I stand at the helm no problem , the slightest move towards the rear or either side will start the inward flow.

Something is not Kosher here
I have almost the same setup. Being a previous i/o should not make a difference. Before my transom inclose the only time water might have come back up the floor scuppers was at anchor with two or more guys at the transom on one side. Now with the bracket, I get NO water. My scuppers have always exited thru the transom even thou the mold has the indents where the previous years the water exited straight down. For some reason it appears you might have excessive weight aft causing your gushers. Have you checked the bracket chamber for a leak that has filled it with water?.

I think having your scuppers exit aft out the transom might solve these issues.
You also could criss cross the drains out the transom with PVC pipe. (Port scupper drains out the transom Stbd side & Starbrd scupper drains aft out the port side)
I would like to see more pics (ex. Battery & gas tank location, baitwell, inside the transom showing the scupper drains and how your boat is sitting in the water etc.)
Lets see if we can find your weight culpret...

Here is an inside shot of my floor drains (prior to the inclose/bracket install) exiting out the transom. Notice that the drains make a 90* before going thru the floor (right side of picture)and then straight out the transom. (Disregard the "T" piece as that was a drain for a floor hatch that was tied in after)


This shot shows the location of the old drain (above pic)vs the new scupper drain location. Much higher after considering the bracket flotation.

Sitting in the water. Notice the scuppers are above the water line
