Hello,
First time pontoon owner and still learning.
I have a 2019 22GSR with Yamaha 115 4 stroke and I noticed that my top speed is about 21 mph at 6,000 rpm. I was surprised to see the attached Yamaha Performance Bulletin indicates that a F115 on a Bennington 2275 GCW ran at 34.5 mph at 6,000 rpm. I do have Ultra Legs (Sea Legs) with a 2nd battery. Would the extra weight reduce speed by almost 40%?
While full throttle, I am not able to trim the motor without cavitation. Is this normal or maybe related?
I am curious what others see as a top speed with their Yamaha 115's.
My boat doesn't have pontoon lifting strakes. Maybe the lack of lifting strakes and extra weight of Ultra Legs is a reasonable explanation for the reduced speed.
Thanks for any thoughts that you may have.
Pat.
