Yamaha 25 hp vs. Mariner 30 HP 

you gotta love that sound of a yamaha autolube

Just rewatched and saw the boat with the camera was the 25hp and the 30hp blew past it and then let off and the 25hp rode past,no racing at all.

We used to have a johnson 18 on a 12 foot boat. It could pull people on waterskis.

my 2 stroke 15 yamaha on the first shallow drive on my 350 dart quintrex with me sitting on the trany goes faster than thoughs boat, and mine has anti fowl with a bit of groath on it,

We Men are so shallow minded. Pure brilliance .i love watching this ........The Mariner thought he had it in the bag ~ WRONG lol

I love 2stroke Yamaha’s. I owned one 4 stroke Yamaha and it was a bulbous pig compared to my 2 stroke. Don’t want another one.

I think 2-3 kmh difference. the 25 Yamaha is faster. Top Speed is 45-46 kmh (gps).

yamaha 2 stroke the best motor

Does anyone on here realize the 30hp mariner is a 30hp yamaha,period.You look under the cowl as i have 2 of them and it says yamaha,i buy parts for a 30hp yamaha..Up to around 40hp mariners were yamaha..If a 25hp ran faster than a 30hp then the 30hp had the wrong prop or beat up prop or,as happened to me on one of the ones i have,it came from the factory with the timing reterded..I timed and its the fastest 30hp i've ever seen.
