Here is a email conversation I had with Parker Sales in 2017 about powering a 2520 Parker with a 350 Yamaha when I was considering selling my 23DVCC for a 25DVCC.

Thanks for sharing this info.
Is there a source available for the older performance bulletins?

Yamaha has a "Performance Site" that has hundreds of Yamaha tests, but it did not have the old one I posted. I forgot where and how I found that one. I take the WOT data with a grain of salt as they are in my opinion much higher than reality.

I dont think Yamaha makes the 350 anymore. On their website they have the 300 and then the 425

I find it funny all the guys here worried about a tiny little 2 horsepower generator on the very back of the boat next to the 1, 2, 4, 6 engines that are running all day long. SMH

Actually, I am more concerned for people who use the term ******* and the damage that may already have been done.

But go ahead Champ, keep on huffing.

I know its not a Parker and its lighter but these performance results with the 425 are quite impressive. I wonder how it would perform on a 2520?

I’m familiar with the Hewes craft.

No way that boat needs a 425. I do not think the performace reports would carry over to a 2520.

Per the parker web site. The dry weight of the 2520 is 1200 pounds more.

Realistically the Hewes is only slightly larger then a 2320.

For reference here is my 2320 next to the Hewes 250.

I know they are lighter but look at the performance data for a 2520 with twin 150's and single 300 vs the Hewes with the same engine combo's. They are very similar, so one would think the 425 would perform very weill in the 2520

It probably would perform well. And I get what your saying.

The cost difference would be interesting. If the cost was the same my vote would be twin 200. Just to have the added redundancy.

Parker will only configure boats to their specifications. No customs options allowed. Otherwise not a bad idea on the 425. All the torque I bet she’d jump out of the hole!

U will be amazed at power and gas usage. 43 is perfect conditions. U can figure 25 to be ur most common area of speed. Mvs dont like waves. However the trade off is well worth it since i anchor alot.
Im going with the zuke 325 duo prop next year . Its a European model. My mv is 325 max hp.

My 2530 MV would run 42 - 43 with a DF-300APX

It's a White knuckle ride.....That speed is Overspeading that hull.

As said..25MPH @ 4200/4300 RPM is the sweet spot.

2.5MPG in the bay and 2.0MPG in the Gulf.
