I have a 10HP Nanni, not quite sure exactly how old - 610 hours on the clock.
I didn't use it enough & the right-angle elbow in the exhaust managed to clog to an aperture of only 2mm before I got it reamed out. 'Use big revs' was the advice.
Just had a big issue with the prop and was told that I had had the wrong pitch on the prop, which greatly impacts the efficiency. That and an antifoul & she goes like a dream.
The exhaust elbow design is a stupid issue - gunk doesn't automatically do right angles. I was quoted $3000 to rearrange the exhaust system including a part to replace the unavailable part. So I'll wait until she gunks up again and ream it out again.
How is yours set up in the engine bay? It's a bit big, given the original design only envisaged a 3hp engine. So there's a bit of an issue getting at the oil dipstick & no idea how to access the gearbox dipstick. Also comes forward into the cabin so access is a bit awkward.
The power's good and necessary here in Port Phillip from time to time, so I don't mind the overengineering...
All the best,
Sean
