new 70 4st yammy
for those looking at mid range repowering check out the new yammy 70 4stroke.....upgraded 60hp.
F70A
New Four Stroke F70. One Step Ahead.
The new F70 is a further development of the F60, sharing the same displacement and stroke. The engine is lighter than any competitive four stroke or direct injected two stroke motor in the 70 – 75 horsepower class. The F70 achieves this by its unique four valves per cylinder design activated by a single overhead camshaft rather than the conventional dual camshaft design for 16 valve engines. This reduces the weight that would result from having an extra camshaft and the components that go with it.
For a remarkably light engine, the F70 punches well above its weight. Four valves per cylinder have dramatically increased this engines volumetric efficiency - the efficiency with which the engine can draw fuel and air in and push exhaust out of the cylinders. Increasing this efficiency means the F70 is able to run at a higher rpm with the max operating RPM being increased to 6300rpm. The resulting top end performance will be great for boaters who want to get to their favourite spot first – and who doesn’t?
The Kimberley....perfect one day and more perfect the next!!!

anyone know how much they cost?
getting the bottom line final answer from a bunch of blokes that use false names and put smiley faces at the end of paragraphs is not the best place in the world to get the information you seek.

Would be good for my boat to replace my old 75hp 2 stroke if they are not too heavy.
Just had a look at the yammy web site, they are saying 120kgs so that should be ok.

it achieves the weight
it achieves the weight advantage because its only 996cc
check out honda (same sohc)
the 75hp is built on a 1500cc motor which would seem a lot less stressed. not to mention a 5 year warranty
Honda is the only manufacturer with every model in its range meeting the world’s toughest emission regulations, including EPA 2006 and CARB 2008.
If I spent half as long fishing , as I do reading this bloody forum , I'd be twice the fisherman I am.

Yeah but the Honda, BF75
Yeah but the Honda, BF75 weighs in at 165kgs and is categorised in the high horsepower range. The next size down for Honda is in the mid range and is a 60hp at 102kgs.
