Nah mate it's one of them Sikk 27's with a bit of very neat tuning
Never had to do anything to it in 3 years apart from change the plug and silicone rings on the exhaust manifold, put a new insulator block on it last week and that's about it. Its getting a bit tired now though as the 29's are starting to catch up with it
I'm thinking of putting my Alro Zen 26 in the Navaho, Mark ran one of these at Sheffield last year and it was ballistic, trouble is they take about 4 hours to run in properly
I also found a new Sikk 27 lurking in a box in my workshop (almost forgot I had it, must have hid it from the missus
know what I mean) so I might stick that in the Navaho instead and save the Zen for one of your newer bigger boats
