Planning on getting a new 25 hp. Make doesn't really matter to me, Any suggestions? Yamaha, Honda, Evinrude, Johnson, Mercury, Suzuki, Nissan, Tohatsu, It will be a tiller and 2 or 4 stroke also doesn't matter.
Local dealer. Visit all of them and discuss your situation. Get a feel for how they are. Do they understand what you need? Do they have a decent service shop?
Make your decision based on who has the best customer service. All those engines are fine.
Since Johnson is fading away I`d go with a Honda. You must above all else consider service from a good local dealer as to wich make you purchase.
The old OMCS were good motors. Until recently Bombardier build an old school 2 stroke Johnston in this range.
I say go with a Honda because Honda has a sweet 25 horse motor, Quiet and smooth.
Like I said you are shopping for service first motor second. All makes are a good bet for reliabilty.
