How did you get the D7 to last this long? I had a look at the Farymann (light and cheap) as a direct replacement. If I remember the D7 is about 60ish Kgs. Farymann also, and I think goes onto the bed too.

No idea of the BMW but I replaced my old Sabb 10 with a Beta 10 about 2 years ago & never looked back. Excellent consumption, far smoother & quieter, and half the weight. Also starts first time, every time, and with the new Gearbox, shaft & prop it actually goes into reverse when I say, not when it feels like it! Incidence of "brown trouser syndrome" has reduced to vanishing point!
Best of luck with the change.

Agree totally with Mike_Mckie. I had a Beta 13.5 fitted last winter. It ALWAYS (sorry, shouldn't really shout) has started first time and runs like a sewing machine on about 1 ltr per hour.
I've just replaced my D7 with a Nanni 2.50 (14hp). It's the same Kubota block as the Nanni 10, Beta 10 and 13.5.
The BMW weighed 68kg, the Nanni 10 is 92kg and the Nanni 14 is 93kg.
The Nanni's only ten hours old...but it's fantastic so far. What a difference - why did I wait so long?
Unlike the BMW, it starts immediately, stops only when you ask it to, doesn't cause an environmental disaster when you lean on the throttle and has oodles of grunt.
Installation turned out to be more than double the quote...and I'm discussing this with the mechanic.
The motor's a bit taller, so it didn't fit under the cockpit floor so well. That meant it extended into the cabin a touch, so the engine bed and the box had to be moved into the cabin by 60mm. The fuel filter was moved off the front of the motor to reduce its length.
