Missing anything ?
Let's revise this a little bit. It's a Seafarer 26, not a Gulfstar 50 for Christ's sake.
Even with installation, a total repower shouldn't exceed $6 or $7,000.
Shore power? $300.00 Where do you get $2k from???
Electronics? A handheld Garmin on sale at WM $179.00.
Hot water heater? Where would he install it? Just use the marina shower.
Stove- An Origo 4000 is $340 at Defender.com
Bottom paint- A gallon of Micron Extra is $250.00, and would give adequate coverage of a 26' hull. It did on my P30. Let's say $375 for haul-out and launch to do the work.
I'm betting you're wrong on the prop, but I have no data at the moment.
The rest, you're probably pretty accurate, but there are significant adjustments to be made to that list.
Still, $1500 for an abandoned boat that is nothing more than a huge question mark, is ridonculous. There are way more better deals out there.
