Does anyone have any more info on the new F70? The current Yam F50/F60 motors also have a 996cc 4 cylinder powerhead. Is this new F70 the same, or a new design?

118 kgs for a 70 f/s, thats superb, current line up is 106 for the 70 two stroke
F60 110
F80 170 kgs.

sure to be a great engine, and on a 470 SR!!

Hi guys!

I think the F70 is based on the F50 and F60.

Here there is very detailed information about the F70 http://continuouswave.com/whaler/ref...70HotSheet.pdf

Hi,

I have another question, are the new SR4.7 fitted with a tube diameter of 50 cm or 60 cm?

The avon-workboat site says it is 19 1/5" = 60cm But thats wrong!! 19 1/5"= 50 cm

Mine's 2004.
I haven't measured it, but they wouldn't be 60cm - that's massive. 50cm seems right.

Hi thanks for the info Downhilldai! Avon confirmed it.

Could anyone tell me what the max outboard weight is for the SR4? It is also not published at the avon workboat site....

I seem to recall the local Avon dealer rigged one with the current 50 Yam to go round the Isle of Wight for a magazine - this was the max HP & weight ( I think ) and even then it was stern heavy so had doelfins fitted.

So I think its around the 117kg level ..............
