New 90-115 on a very light rib

www.dahlnaval.se and the small 18 enduro.

Mercury 90-115 optimax.
Evinrude 90-115 e-tec

Or

Yamaha F90-F115
Suzuki DR90-DR115

I will use the rib for longer trips and for daytrips, and i will not drive full speed all the time. But yes it is fun to go fast also

I like the servicecosts for 2-stroke and the sound and acceleration.


But also to go with this boat in 25-30 knots is very economic, if a boat can be that...

Which engine do you prefer in my case?

I looked at the Yams when repowering the boat, I chose the etecs as they are smaller and lighter, first service is meant to be 3yrs or 300 hours (however they will be getting a service this winter for piece of mind).
