Hi, I have an IP31. It came with propane. The tanks 2- 10 lbs are in the small
hatch on the left side cockpit seat, I think it may be used as an out side icebox. the hose comes out under the ice box undre the
stove. I dont know the cost but figure a new
stove $1,500 2 tanks $300 regalator $150 electric cut off and gas detector $300, hose parts and extra stuff $$ two cases of beer a couple of friends, a cool day or two. I have not done it, but it looks streight forward. Hardest would be running hoses.
After you get the boat, regester it with island packet. They will get you an owners manual if you dont have one.
Join the IP31 owners group. Jon Bickel has a news letter. Owners have made lots of upgreads and have photos and suggestions. I have used it alot. Most has been figured out already, so you can just pick your project with out to much thought. You can post any problems here or at the IP site and get lots of help. I really like my boat.
If you have not gotten it yet, pay atention to all the tanks. depending on the year thay have problems. When I got mine it had already replaced the
fuel tank. I had to replace the
holding tank and water tank. Also thru hull valves I replaced as two were real stiff and one, the head dischargewould not turn and was frozen OPEN. But All in all a great boat.
