Engines, i can potter around with engines all day, and still love doing it as my living. I can take one completely apart, and change almost everything on the rocker box and put it back in the boat in a day.

Infact, not too long ago i was fixing my mates outboard for him, [it was jumping in reverse, and when he floored it forwards it started jumping.]

Well, for a start the carboretta was leaking every time he manually pumped petrol through, so i replaced it with one from and old outboard i got in my workshop at work, and then i sorted out his gears, cos there's a roller that keep the outboard in gear, and he'd somehow lost it so i used anther one from another broken outboard that i found, cos before i did that it was replying on the cable to keep it in gear, and with something like an outboard, the vibrations are too much, although this is a nice honda, really quiet, sometimes you cant even tell it's running.

anyway, yeah, i like engines to put it plainly.
