Gasser airboat

[n2hyo]

I have been thinking of building a weedeater airboat with a homelite 25cc
engine and running a 16x8 prop one it. Tonight i just found out that Ryobi
has a 4-cycle 26cc trimmer. It is rated at 6800-7800 rpm so it should be
about the same rpm as a 2-cycle but swing a bigger prop. Does anyone have
one of these Ryobi 4-cycle trimmer ? You think it would be worth picking one up or waste of money ?

Any input welcomed

Thanks Mike

No clue about that, but why not just pick up a Zenoah?

That one will spin an APC 16x8 at almost 9000rpm (LOTS of power, outperforms a Homelite any day)
