I don’t get it......
Why a 4.6 litre V-8......
Yamaha’s R-1 bike engine has been around for years.
Very similar motor now used in sleds...
4 cylinder 1000cc
Depending on the level of tune and the use of a turbo or blower....400 reliable horsepower easy.
I’m not being critical of Mercs new creation I just can’t figure out why it takes that much displacement & 8 holes.....
I think it's longevity. I think the Yami 1000 is a great motor too, but it's mostly used on platforms that weigh the same as it does. To produce the kind of torque it would need for marine use wouldn't be as easy as adding cylinders. Yamaha had a four stroke 1000 cc outboard, not sure if it was the same platform, but I think it topped out at 115 HP? Now that motor is a 1.8l. I'm sure Doc will correct me if I'm wrong on that lol....
