With my holiday offsite for a while, I started pulling the Chieftain apart inside. I removed the side panels to access the fuel tanks. Holy crap they’re big. They must be 5’ long each, hopefully there’s a tag on them so I can find out the capacity. She ain’t going to be cheap to run that’s for sure.

the box that holds the icebox is rotted and when I pulled the back off the was an intact paper wasp nest the size of a melon. There was also old comb the size of a small dinner plate 3 layers thick. I’m sure as I pull things apart I’ll find more. The dividing wall into the cabin needs to be replaced, the door needs replacing and both jump seats need replacing. The seats/bed decking in the cabin is solid, the head is intact as are the vent and pump out hoses. The transom is near non existent and judging by the big jug of hydraulic oil, the trim tab pump must be leaking.
I was a little worried that the rear rub rail was off but it, the channel and corner caps were stored inside, even found the original screens for the cabin, all intact. No plans to really do anything other than remove the rotted out carpet and wood. This, along with the pile from the Holiday should give me a full load for the landfill site.
As solid as the floor feels, I’m pretty sure I’ll pull it all up if only to check the rivets that attach the stringers to the ribs. My holiday had about 25 that broke away. Anything that has been added over the years will be removed and the holes made to attach them will be filled.
Did these boats have seats in the rear? With the doghouse in place it doesn’t look like there would have been, just not enough room. I’ve scoured the net but have been able to find any good pictures of an original interior. Hopefully I’ll remember to take more pictures as I progress in the gutting.

Yeah those are some large tanks, probably around 30 gal each it looks like.

Most of the IO's came with jump seats on either side of the doghouse but most haven't survived by the time we find these old tinnys.

With the doghouse in place it doesn’t look like there’s enough room for seats beside it. The person would need to be rail thin to sit there. I haven’t been able to find any pictures online of the back end of an original express.

Since family health issues have put my boats on hold, I’ve been thinking about the head in my chieftain. It’s a small porta-potty type mounted to the floor with what looks to be a built in 5gal. holding tank with a vent and pump out hose attached.
I’ve never had a boat with a head so I’m wondering how long it would take for the tank to fill with just 2 people using it? My ultimate goal for the boat is 2-4 day trips on the north shore of Lake Superior. If I find the attached holding tank isn’t big enough my thought is to disconnect the pump out hose from the built in toilet holding tank, add a 20 gal. holding tank in the bow area and join them together with a macerator pump in between. When the toilet holding tank is near full, I can then pump it out into the bigger tank. I would add a vent to the larger tank and re-route the pump out hose to the new tank. This would ensure I have holding capacity for the 2 of us for 4+ days or for day trips with guests aboard. Does this sound feasible? I’m pretty sure as long as nothing can be pumped overboard it should be fine legally. Has anyone done this? I’m thinking this is probably the most cost effective way to add capacity. Flush water can easily be filled with raw fresh water from the wash down pump.

bet they are only about 15 gallons.

measure length x width x height and then divide by 231 to get gallons

looks approximate 4.5 x 13 x 58 which is 14.7 gallons
