I have a 1999 Adventure 208 and plan on replacing all the thru hull hoses and bait tank hoses. I am dreading taking these apart and putting back due to lack of access. Anyone have any tips on getting access to these hard to reach hoses? Anyone do this recently? Tools, tips.... anything that may help would be appreciated! Thanks!

I did it last spring. A nut driver and or a 1/4" drive ratchet with extensions worked on the clamps.

Removing the pie plate frames gives you a larger opening. I cut the hose off fittings I kept and just broke off all the plastic thru hulls that I subsequently replaced with stainless.

I removed the frames and wood from the underseat storage box and drawers to gain access as well.

Gloves and long sleeves are a good idea, lots of sharp shards of fiberglass. It's a pita but worth it.

On mine the two floor drains by the seats and the live well and fish box drains are 1" hose.

My bilge pump was 1 1/8" and the two rear scuppers are 1 1/2"

I used clear reinforced hose on the drains and bilge pump and fuel fill hose on the scuppers as I did the fuel tank around the same time so I ordered extra.

Thanks for the detail Paul! Appreciate it! I have not yet removed the storage boxes under the seat, was there framing there that prevented you access to the deck scupper hose?

I will remove all the round hatches, and replace with the Spin On Beckson round hatches as well.

If anyone else has advice - keep it coming.

I made this tool with a socket that fits snugly in the outside of the thru hull, and a grinder. Since it is so hard to work in the small openings, if you can just get someone to hold a wrench on the nut, you can do all the turning from the outside, using the 2 small tabs in the thru hull.
Whatever you use to hold the nut on the inside, tie a string to it, so that you can retrieve it when it slips off, and out of sight. Stick your camera in all the openings, and take pictures of what is out of sight on your boat.

Thanks Glacier! Luckily, I have the 1999 model with Brass thru hulls, so I only have to replace the hoses.

It's been 8 months so I can't quite remember the exact process.

I just looked as it was 8 months ago so hard to remember but you can access both ends of the forward deck drain hose through the pie plate opening but it's easier to get to one of them through the underseat storage box openings.

And no, the stringers nor any bulkhead are in the way. The real pita is the hose clamp on the drain fittings for the bait well and fish box. Mine have a shit ton of spray on foam around the boxes so hard to access the bottoms.

My 87 226 needs all the through hulls replaced obviously for safety, but my forearms are too large and will not fit through the access holes. I'm hoping to find someone with thinner arms that can assist me, most certainly will be a challenge. I coated all the exterior faces of the drains with a thin coat of 5200 so the small dry rot cracks are sealed for the time being. Hope to tackle this during the winter months when weather is foul.

That's a heck of a tool. Will definitely give that a shot when I do it. I can foresee running one of those fiberglass snow stakes through it and using it to position and feed the hose.
I think the hard part is getting to the nut and holing it. On the boats with the aft door to the eurotransom that is the challenge.

I started replacing all my through hull drains yesterday, the old ones mostly crumbled once I tried to remove the hoses from them. The forward fish box and floor drains I can't do until I figure a way to get to them, the access hole is not big enough for me to get my arm through. Most likely will have to add a bigger access panel.

Bummer on the access panel. I have a teenager I will have help me out, hopefully, I don't have to go that route. I'm waiting on the spin on Beckson hatches before I start.

My experience, as well, and should be taken seriously by anyone with the old white thru hull fittings. No bilge pump is going to keep up with the flow thru a one inch, or larger hole. We all know how hard they would be to access and plug from the inside, and the next 6 months are not a time that I would want to have to go in the water in NC to plug a leak.

You have to watch the hoses too. They are prone to dry rot and will need to be changed at some point. I dread having to cut the deck to access. The new scupper drains look to be a nice upgrade as well.

I replaced the back five through hull drains and hoses for the twin live wells, bilge pump outlet, and one bottom live well drain today. A total PITA to say the least! Access was through the battery compartment and oil reservoir compartment, barely was able to get my shoulder and arm in position to get it done. Those are the easier five out of the ten the boat has.

I'm thinking I will have to cut in new floor access holes for the front floor drains and fish box drains. o_O Sorry, but I can honestly say that access to these should of been thought out better in the 226, something that can deteriorate and sink your boat needs to be serviceable. What a nightmare!
