Yep the zuk 70 is quite a lot heavier than the F70 from the research I have done.
rahui wrote: the advantage with the yam is that it is the perfect weight for a small boat,the power to weight ratio of the f70 is new technology, probably one of the greatest achievements in motoring technology there aren't too many 4.5 to 5.0mtr boats that will enjoy 160kgs strapped to there backs, but they will handle the 119kg yam 70f. I think suk don't even put out there weight for the new 70, they must know that it cant compete with yam. |
I drove both boats at their conference, the Yamaha boat was set up by a Yamaha dealer and pulled 6400 rpm fully trimmed at WOT. The Suzuki pulled in it's operating range, and I actually think that other props may get better results as there was another 300 rpm to play with. The big difference is cc, prop diameter(13 3/4 inch compare to probably 11 1/4) and the Suzy gear ratio is 2.59:1. They did a shootout a few years ago on 300hp, and the Yammy V8 did well on speed and holeshot due to the same reason cc and torque.

theres no new and amazing tech in the f70 - theyve simply put a new head on and raised the rev limit on their 1litre engine. =70hp - im sure suzuki could do the same thing with their 40/50/60hp engine if they chose to. as stated earlier, the suzi 70 is a much larger engine and is based on the 1.5litre block, which it shares with the 80 and 90hp engines. specs for it are on their website for all to see... |
pirate wrote: Yeah funny they don,t mention weight specs in that add.. I see they are not much lighter than a yamy f80 (154kg vs 170kg). I,m looking at an f70 upgrade soon for me 5mtr ali. basically a sack of cement less on the bum than the zuk. power to weight ratio overwhelms those figures in add surely |
