I can only make observations Fenlander.. but that wee boat went like a BAT out of hell
I thought it as fast as Stig in his Honwave unless it was really rough..but as mentioned..I suspect that was boat length rather than engine or hull shape.
A lot faster that the aerotecs..but they may not have been going full throttle...when Stig and the other Guy was
The guy enjoyed pulling wheelies etc ..so loads of power low down. It seemed quite quiet too..but I may be wrong thinking that..as I get deafened with my own 25HP two stroke.
I couldn't believe how quiet Stigs 20HP four stroke was.. at times I had to ask if it was running..when he started it on tick over.
I love my wee 6HP 4 stroke because of its low noise..It tires me listening to my 25HP on long journeys..so I think you made a good choice ..if you can manage the weight.
I had a wee haul of the Jaga on the beach too.. and it was very light to move..which was not a surprise.
Thats about all I can tell..perhaps the owner will comment ?
