Why are nearly all Parker boats underpowered?

Just a question that's been on my mind for some time now.

Take an average 25 foot Radon, these boats tend to have 350-450+HP. Take an average 25 foot Parker, it'll have 225-250HP.

I get that the Parker is lighter, perhaps by 30%, but the V in the hull alone would potentially justify that extra HP seen on Radon's or other SB-style hulls. More is often so much better.

Perhaps Parker boats come under-powered due to a cost issue?

Curious to hear some owners weigh in on this.

What's the max hp rating for the boat?

I think they don't compensate for the Deep V model. The Mod V's are great with the power they come with. Put that same engine on the Deep V and the boat is almost useless. I have a buddy with a 25' Mod V and the 250 Yamaha pushes is great! Cruises at 22 Knts - tops out at around 30. Put that sucker on a deep v and you are 4,500 RPMs just to get it to plane at 17 knts.

The 2120 which I have comes standard with a 150 HP which does not move the boat. To your point I have the 200 on mine which is perfect.

The 2120 has a max hp rating of 200 so 150 sounds weak. The 2520 dv has a max rating of 500hp so I would think a 250 would really struggle!

Yeah, it's like always 50HP less than it should be. Is the cost really that much? I'm sure it would be worth it, hands down, with enriched user experience.

Looks good. Do you think it's under-powered? I have a 300HP on my boat (24 SeaRay, 8,000lbs) and it's great. Could be more, but I really don't need it.
I don't feel like it's under powered at all. A 250 on a 2320 would probably be the least people should go on that hull but the 300 is the perfect amount of power

We got on Parker 2520s when we were looking and some had twin 115hp. Severely under power. I dont believe twin 150s were much better. We went with twin 225s and have been happy. Many new ones go out with twin 200s which were not available when we purchase ours. I think the under powered options were probably due to cost. Ours is the deep V.

You have cost and available technology to consider. The 25 is rated for 500 HP but that amount of power is not necessary. With my experience I would say 400 HP is perfect for a 2520 or 2530. And now Yamaha has the 200 HP in the 4 cylinder so a pair of those would be ideal. I'm at 300 HP with twin 150's on my 2008. Although not ideal, it was acceptable once I switched to 4 blade props.

It also depends on the number of motors you want. I like having two. With the availability of the 4 cylinder 200's it seems like Parker should make this standard power on any of the 25's with twins.

Never been on one with the twin 200s but that does seem to be the go to option for twins.

Thank you, very good explanation. Makes sense. Overall, how do you rate the hull of your Parker? You seem to have a great grasp of your boat. For a production boat, what do you think? Would you head 50 miles offshore with it?

I've been offshore about 60 miles out, been to SBI and lots of local stuff. The most miles in a day was about 140 (was 85 gallons of fuel). This is my 2nd Parker, the first was a 21 DVCC which I had from 1999 to 2010. There is no comparing the two boats but I've been satisfied with the way both handle and ride.

Boats are like cars in that there are folks that love or hate certain brands. As I said originally, you have to consider cost. I'm not on the boat enough hours a year to justify a 25 footer that would have cost twice as much. I did look at a used 2005 Farallon 28 when shopping back in 2010, but it was not clean enough for me and it would have cost $40K more than my new 2530. Plus I really wanted two motors.

I'm very satisfied with the way the boat rides. I most definitely would not use the word "pounding" to describe it. My 21 DVCC was too light to pound. Was more like a rocket sled with the 200 motor. The 2530 has a bracket so it rides more like a 28 footer, plus the bigger house puts more weight up front. If I have the bait tank (dual 45 gallon PE) full that's another 700 pounds which adds to the momentum for cutting through.

I would advise anyone that has a 2530 with twin F150's to go to 4-blade props. It really changed the drive-ability of the boat. I only lost a couple miles per hour on the very top end and I'm rarely running at 35 knots anyway. I can keep the boat on plane at 3400 rpm when it took 3800-3900 with the 3-blade SS props.

My overall mpg is about 1.5 to 1.7 and I believe that with 200's to overall mpg would be more like 1.6 to 1.8. Just guessing from what I know about the F150's and what I've read about 200's.

I could not disagree more. I have a 2520 with a Volvo D6 310 diesel. Rides like a tank.
se your power power plant is forward of the transom.... must agree rides like a tank....

There was a 22 Defiance pilot house at Fred Hall with a 150 motor. I would have figured it would have had a 200 or 225...
