...... upgrades can you do to these motors.....
Anything you want, responds the same as the 6BT (aka B5.9), but as noted above, about 2/3 the power/torque, and a bit more vibration.

An in-line six 4 stroke is inherently balanced, an in-line four is not.

Really.......it depends on what you want to do with it.

If you get one, try it like it is. For "only" 105 HP they do really well, and you might be happy the way it is, stock. There are improvements to be made that are pretty easy and common to do.

Have a look around, read some and learn some! :)
