Commonality is important in the marine industry. 300s in the field are likely 20:1 against 425hp.

I would get the 300s.

With respect to performance - the cruise of both options are identical according to the yamaha bulletins 3500rpm, 36mph, 1.4mpg

Top speed is a little different but not really relevant for me - 300's 62mph, 425's 59 mph

With respect to offshore fishing, if you lose one of the 425's, do you think you can get the boat to plane on one?

More maintenance costs with a 3rd engine. Higher initial cost with the 425's.

Thoughts?
what about the weight...how much does the 300 weigh...I know the 425's are like 950-975 lbs. each..

I think the 300s weigh around 600 pounds each, so I think the weight is a wash or pretty close. I decided to go with the 300s, I hate the higher insurance costs, but I can live with it. Boat should be in by the end of November, Ill post pics then!

i heard exactly the same thing from a Grady salesman today. He spoke very highly of the 300.

The 2011 -2013 owner's manual say Premium as the recommended fuel. From 2014 and on the owner's manual say Mid-grade as recommended. 89 has always been the minimum octane required. And trip 300s is the right answer.

Trips all day long.
Much quieter and the ability to get in plane with the remaining 2 engines if one goes down. That said, you dont hear of the 300s going down very often. Love them on our 34 Regulator.

But those twins have far more parts on each engine that can break.

The 300's have been proven to be one of yamaha's best motors they have produced. If you can get by the oil making issues in some of them,then you should have a great set of motors.
