It's still early on this thread though.

In a surf boat, I don’t think you are chasing a hole shot that is .2 seconds quicker or a 1 mph higher top speed but rather more low end torque to get a very heavy water ballast carrying boat moving and keeping it on plane at low speeds while surfing. Does the 430 do this better? At this point, who knows? But, I’ve noticed most of the dedicated surf boats out there have options running from 380 HP in the smaller boats to 600 HP plus. If it was my build, I’d spec the 430 hp engine. Let’s face it, on a $250,000 R8 surf, the option is about 4% of the cost of the boat.

I have a 18 R7 Surf and have loaded it up with more people and lots of ice chests full of beverages than most and the 380 has performed well from surfing to tubing, to wakeboarding, to loading up and cruising across the lake to our favorite beach to meet friends. I am thinking about ordering a R8 surf this fall and I will have no reservations with ordering the 380 again and saving the 10k to spend on other fun items. Just my .02. In fact my R7 Surf loves the load and it makes the wakes so much better when we are fully loaded vs only having 5-6 in the boat.

Keep in mind the R8 is about 1,000 lbs heavier than your R7 and may also carry more ballast. But, by the time you are ready to buy, your dealer should have a unit in stock with a 380 to test. It’s interesting that the demo video boat is equipped with a 430.
