Hi everyone, I am new to this so dont laugh. Does anyone know how water gets under the floorboards in a Norman 24? I left my boat for a year and it had a good two inches of water under the floorboards when I got back, had to scoop it out today.
I bought my Norman up from the River Medway recently but only went a few hundred yards and by prop hit the bottom (long shaft) and cost me £800 to repair (Honda 15hp). So I lifted it up higher but now its so high its hard to steer. So much so I am terrified to go anywhere in it lol. Then I went under snarestone tunnel and ripped my windscreen off, (so not a good start). Anyway, I plan to live on it for a year and save up for a deposit on a proper narrowboat.

It will be rainwater in the bilge, a prop strike costing £800 was good one, where you doing 30knots at the time?? Someone stitched you up there methinks.

Wow, what did the prop strike do, wreck the gearbox?
I struck my 15hp running at about 5 knots, hard enough to knock it right up.. didn't do anything other than cosmetic damage. |

I hit a concrete step in reverse on my RLM with enough force to stop a 2.5l bmc diesel @ 1500rpm absolutely dead, a bit of dendro-percussive maintenence on the prop later and it was good to carry on with, a bit of welding and dressing when back home and it was fine.
New enfield props are only £160, must be able to get a prop for outboard for about £100 new.
That said got shoved by incoming tide over a washing machine topped pile of crud going into boston and it cost my insurance company £2.5k as it smashed both outdrives, not the sort of impact you get on the river in normal use though.

While we are on underwater impacts.... Can you spot the before and after pictures....
Look at the angle of the P bracket in the before...
Compared with the after .....
It's best not to ask how much....... but at least the insurance is covering it.....

He said it bent and twisted the shaft and he had "never seen anything like it". I had to take his word for it.

Thanks, I am hoping it is just rain water. I have large bubbles in the fibreglass (on the inside) of the hull, more like lumps than bubbles, but didnt notice any on the outside of the hull when it was out of the water for transport recently. Not sure if thats Osmosis as I thought Osmosis was on the outside of the hull not the inside? Every Time I empty it of water more water appears, not much but I hate the idea of sleeping in the wet boat all the time. Plus its made the wood in the v-deck section rotten at the bottom and I am worried one night my bed will collapse. So I am going to fill the v deck section with pillows and old douvets so if it does collapse in the night it will be a soft landing.

I had a similar wet floor problem. Turns out it was water leaking in-between the skins around the window frame.
I had to conduct a laborious process of illumination to work out where it was coming from. I cut a hole in the fibre class that was encasing the length of wood in the bottom of the hull (don't know technical term) and found a short length of the wood to be wet/ rotten. So dried it out, cut out the part that was rotten then left the hole to use as a spy hole.
Taped bin bags over all my windows and and potential leaky points, then waited for the rain to come. With every rain storm I'd remove one bin bag and keep checking the floor for water. Eventually I worked out that my hull only filled up with water when the window on the left was left binbagless, therefore highlighting it as the issue. So I took the window out, cleaned it up and sealed it back in. So far no more leaks.

Chalkdust is always useful for tracing leaks but doesn't help when it's between the skins on the roof.
I'd have wanted to see the shaft for myself, outboard props have rubber hubs to absorb the worst of impacts (smaller outboards have shear pins), I've had a bent shaft in an enfield before and sorted it out with a hydraulic press checking between centres with a dial gauge each adjustment then crack tested afterwards, took .032" runout down to .002" and stopped the oil seal leaking, I guess it helps that I've got access to the gear at work.

| Check the easy stuff first and remember that the water ends up at the lowest point it can get to but may have started elsewhere. Common rainwater leaks are the canopy and the windows. Inspect the window seals and check your window drains are not blocked. Also, check your water tank and pipes. |

| Even though there is no way (theoretically) for water to get in with a stern drive, as has been said, rain water does gather in the biges. I simply installed a bilge pump at the lowest level. I was "lucky" enough to have a spare "hole" in the stern near the water level to attach the hose to. Don't ask me why the hole was there! The answer likely lurked some 20 - 30 years ago! |

| I get a lot of rainwater gathering in the bottom of the boat because I have no deck or canopy. On the plus side it means I know that the hull is watertight as I have to keep bailing her out! |

I have no worries about rainwater collecting in my bilges at the moment, I have 22 1/2" holes in the bottom for it to drain through.....
Good job it's on blocks and planing on doing some filling this weekend.

Water under floorboards
