Is Yamaha 115 4 stroke enough power for a 73 Seafari ?

Forgot to mention that it is a 73 20 ft Seafari

If you get either Gillie or Ken Reeves (PropGods) to dial your wheel in I believe you would see something like -
Minimum planing speed - 15 Mph
Cruise Speed - 20-24 Mph
WOT - 33-35 Mph
You'll probably be well north of 3 mpg.
If that would be suitable for your use, you will be happy with that motor. Have it serviced regularly and it will treat you right.

Thanks Terry for the info. 30 to 35 is as fast as I need. The 86 150 topped out at 44 mph and I rarely ever went WOT.

I am just one "Data Point" and I'm sure others will respond shortly. There are a few here like me that run 90's on the 20 footers and I think "Tiny" has a 90 on a SeaFari. The nice thing about the 90's or 115's is you don't blow the beer out of your cup on the way home! You can sit back, motor along, steer with your feet and tell extremely "tall" fishing tales.

Balance and min plane speed are some of our favorite friends.
