Default Highest safe nitro% for Miss Lumar

What is the highest content of nitro I can run in the Lumar without having to worry about the motor, or make any changes to the motor?

I've run 55% in my small engines but I'm crazy![sm=bananahead.gif] 40% would be a reasonable maximum but the important thing is oil content plus a good brand of fuel made for boats. You'll find out that in this heat wave that we're having that lower nitro will make the engine more tunable.
If you're in the need for speed, try other tricks mentioned in the Bud thread, same boat.

No, it has a lower oil content and neither is plane fuel good for boats. Helicopter fuel is a better alternative if you have trouble getting a good boat fuel. You want to find fuel with an 18-20% total oil content by volume, not weight.

I buy lots of stuff from Tower, but fuel isn't one. It ends up being way too expensive. Your best bet is to find a local shop, they have paid for bulk shipping, or a group of local boaters to see where they're buying their fuel. The NAMBA site: http://www.namba.com shows some clubs, one might be near you.

Great, that works much better. Now you need to burn it so they'll stock it more often!
