YAMAHA F100
« on: October 19, 2017, 10:08:18 am »
I am considering re-powering my 19ft Tom cat and the new Yamaha F100 is one of the options.

Can anyone help with info regarding hole-shot performance and fuel economy based on personal experience with these motors on similar sized craft?

Many thanks

Johnny

Hi Johnny
I have just got a new Seacat 565 with F100's on. I have only tested her up here at the Vaal river, where I got 63 kph so at sea level it will go over 70 for sure.
I am off to Inhaca on the first of November for her first saltwater trip. I will give you better feed back when I am back.

Hi Johnny,

I have a set of the new Yamaha 100's on the back end of my Seacat 565, upgraded from 2 x 90 2 strokes in March this year......one of the best choices I have ever made.

I thought that due to the increase in weight I would feel a difference in performance, trust me, the new 100's outperform the 90's any day. I only launch out of Richards Bay harbour but am sure that these 100's will take you through the surf like a hot knife through butter.  From a standing start, getting onto the plane is almost instantaneous, 2 to 3 seconds and you're flying. Top speed I have achieved on the open sea is 67km/h, running at about 5600rpm.

I do not have the exact fuel consumption figures, but what i can say is that after riding and trolling for a full day, doing in excess of 90km on the water, the 100's had used a tank and a 1/4 on each motor, probably anything between 25 to 30 liters for +90 km.......couldn't believe how fuel effecient and light (not to mention quiet) the motors are.

Hope this helps in convincing you to go out and get those 100's, you won't be sorry
