Nanni Diesel v Beta

[dragoon]

Dont see the problem of cam belts, change them every year with the impellor, then you know its ok, it's not as if it's a huge job and they are not expensive. I chage all my fan belts on my engines every four years, three in hot climates, where your engine room ambient temp is higher. Genny belts evry 200 hours, as they run at very high ambient temps, in the soundproof housings and the flex goes.

If it's necessary to change a cam belt every year, this indicates that the use of belts instead of gears on a boat engine is a very poor choice. I get tired of changing timing belts on our vehicles, and the interval is minimum every 4 years, ignoring mileage. Even as I write, our VW T6 is in for a cam belt change - the best price I could find was around £500. I used to do it myself on our old VW T4, but it was a pain - the crank bolt was tightened to 460nm!

To my mind it's a poor design. If gears are too noisy for cars, I'd be happy with chains like the old days. I've only ever changed a timing chain once and the engine had don 340,000 miles.

As stated by others the Nanni and the Beta are both based on Kubota engines.
The Nanni is the official mariniser for Kubota.
The Nanni has a lighter flywheel which allows easier pick up.
The Beta 13.5 is 14hp as a Nanni The Beta 20 rates at 21hp as aNanni
The Nanni has a 3 Year Warranty
Nanni has a world wide service and spares network.
A comment from one Nanni owner I met recently was " The only problem with the Nanni is that it is so good it is making me into a motor boat sailor.

Nani have suprrior marinisation without a cocktail of dissimilar mets therefore fewer anodes to control electrolisis plus better heat exchangerers
