I just got a mega-super deal on a brand new Mariner 25 HP 2 stroke. The poor thing was bought and put in the garage in 2004, and never seen the water. So I got it without ant scratch or dent, the gear oil never changed, the implelor still original.
I was wondering if I can get it uprated to 30hp. I have red the threads about, but the engine I have seems different. How can I tell if this is a Yamaha or Tohatsu?
The flywheel is not dented, is plain like on the pics (from Internet, but mine is similar) and the numbers are marked from 0 to 40 in both directions.
Could anyone tell me if this engine is upratable to 30 HP? Thanks to help
