Not knowing what's blown it's tough to guess.

Figger about $50+ for rings, $30 for seals, $50+ for a gasket kit, and a
good $100 per piston.

To meet those numbers use Sierra or Pro-Parts - Mercury will rape you and
forget to use assembly lube on your ass!

If it's a chrome bore you may need to get the block sleeved if a bore is
damaged. If it has steel sleeves, all you'll need is an overbore.

While you're there you prolly wanna do up the fuel pump and the carbs. Add
a few more bucks for kits.

As for the motor itself, I prefer the inline 6 up to 150hp. But that motor
had a good rep. What you wanna do while it's all apart anyway, is find out
what other HP's that block was used in - and what's different - you *might*
be able to hop it up a bit.

Hey, Clams, I've got an opportunity to pick up a nice boat, but the
motor is blown. I can get the boat for what I consider a good deal for
the boat only. The hillbilly doesn't know what exactly is "blown".
It's a 1987 150 Mercury XR-4. Any idea how much parts would run for a
decent rebuild? Let's assume a piston or two, rings, bearings, etc. Is
this a decent motor, if one WAS to make it run decent again?
