39kg against 26kg? That's 18 litres of petrol! He can't burn that in a day on the water...

You've got him on the warranty though. Although there's not much on one to go wrong.

These little motors rock....26 kilos and run as sweet as a sewing machine.

I got one of these 9.8 from this guy, he gets them set over from Poland I think, went to his place it was like 2 smoke heaven, as everyone seems to agree it's a great motor

Working on water at 10lb per gallon it's about 2.5 gallon 11 litres it's only an off set and barely noticeable but it's there and adds up when you start loading especially when your pushing it on HP.100 cheaper on two smoke though new.

Big mistake IMO - I'd stick with petrol for the OBMs. It's more expensive but much lighter - almost 30% lighter. You forgot to factor in the sump oil on the 4 stroke too. BTW, It's Poly's evening off and I'm minding the slide rule...

At your age you'll have to weigh it more frequently :-P

Anyway - I checked Poly's notebook and it says that petrol has a range of weights, from around 710g-740g/L, depending on the level of aromatics in it. He's mustard is that lad

Thanks Jeff and everyone else

I wouldn't bother getting a 38kg engine as my current 15hp is 44kg - 6kg isn't enough of a saving to justify

However dropping to 26kg is a big decrease

I had been under the impression that it was pretty much impossible to get a new 2 stroke and I'm delighted to find out that I was wrong !
