There should be no water, unless your boat drains into the bilge. If it does, you are probably stuck with that design. If it doesn't, you owe it to yourself to figure out where the water is coming from. Large quantities are usually easy to find. Once it is down to a cup or less, it gets tougher. Some rod holders will drain into the bilge (the good ones don't). AC condensers can drain into the bilge. Some deck hatches allow small quantities of water in (but the better design, with a vented-lip, do not). Dripping hose fittings are often a problem.

Water always seems to find its way in somehow, but I am adamant about figuring out where it is coming from. My most recent boat was a leaking bait tank lid when we were in rough seas. It was almost impossible to see. I've had bilge discharge holes that are too low and take water in at certain angles, through hulls leak, hose fittings leak... take a day, flashlights, and tools, Then have a friend drive while you look. I never took on a drip in the bay, but like I said I took on alot when in rough seas from the bait tank. Good luck!

    wash down pump, bait tank, engine water pump, fresh water sink or toilet, possibly a thru hull fitting, out drive leak - best to wash down boat and check to see if water in bulge (this would rull out top side entry) the put your boat in the slip, turn on each pump for 5 minutes and check bilge, last resort get into the bulge with flash light..

    Have you checked outdrive bellows for cracks etc? If you can figure the general area in the bilge the water is sourcing you could narrow it down. Starting out with a completely dry bilge, tape or secure some medium, like pieces of carboard in different area's in the bilge; after short duration of running on water see whats getting wet - keep checking bilge until first signs of water start showing; or secure a gopro camera in bilge. Good Luck, keep us posted.

    Check your exhaust y pipe for rust holes. I had a friend who developed a dime sized hole just above the resting water level and it would leak into the bilge when you stepped onboard. You couldn’t see it until we removed the exhaust (and obviously the engine) but you could see water run down the inside of the transom, we thought it was the transom shield originally. I’m not familiar with your exact setup but it’s a hidden area on IO’s.

    Mine has one of those square lids you slide in and out, and in rough seas it sloshes out some even with the lid on. How did you fix that?

    I added door insulation from home depot and covered it in silicone. It still compresses like it should, but it doesn't hold water. There are all types of thickness available. Gotta get creative sometimes!

    Run the engine a while and see if it is adding to the water. Eliminate everything one at a time, wash down, bait pump…. Good luck

    As mentioned above, the impeller cover is on the list of likely culprits. Do you notice any part of the engine being wet?

    Depending on where your thruhull for your bilge pump is you could be getting water pushed back thru the pump into the bilge.

    notice if there is more water after washing boat down, the fish boxes and anchor rope storage could drain to bilge. Also check exhaust for drips anywhere.

    No matter what, my skippy always has water in the bilge. I put rubber expansion plugs in the scupper holes to reduce bilge water, but always have at least a gallon by the end of the day. Wash down pump, etc will always put water in the bilge. My deck hatches aren't sealed nor is the engine box. I have 2 rule 1100's on an auto switch that are in place and can also turn on manually if needed.
