Probably add to that, the power steering cooler that is mounted on the rear of the engine like OMCs had it.
This is one of the main reasons people are going to outboards, no one wants to deal with the hassles of draining these things every time the temp drops, and the boat companies make it worse with idiotic designs with no access to anything but the dipstick.
In fact, I am thinking of getting rid of the big back seats on my boat since they are rarely used, and replacing them with lightweight jump seats to make that ordeal easier.
Michigan Motorz sells long block packages ready to drop in but they are expensive, like $9000, including carb, ignition and exhaust but keep in mind your original engine is a 1999, that's 27 years old, so changing everything while expensive, might give you a better outcome because the parts you need to be reliable will be new.
Or, you can get a reman from a local machine shop and add the extras (intake manifold, exhaust manifolds, etc) yourself. You can still get new long blocks from Michigan Motorz and others, but the price has gone way up from what it was like 5 years ago. It depends on what you think the boat is worth and how long you'd keep and use it.
