underpowered Maxum?

Not enough info. Need beam, weight, deadrise, total fuel/water/stuff. Generator? How are you going to use it, what is the normal pax load, etc, etc.
I know that asking for that data seems obtuse, but long away and far ago, I had my arse handed to me by a guy in an aluminum john boat with a 35HP antique engine when I was in an 18' deep V runabout with a brand new 140HP OB. Last summer we were watching a poker run in the James River. The guy going the fastest wasn't even in the race. He was in a 21 Triton Bass boat looking for fish passing all these high dollar high power testosterone machines. Now could he have competed when they made the turn towards VA beach. No way in hell.
It's all in what you desire for performance in your given situation.

with twin 5.0's it shouldn't be underpowered...but that is more like saying when is enough power enough??...I mean your using 440 hp in two engines pushing about 12k of boat....does it get you where you want too go??...is 40 mph fast enough for you??...it's all relative...so...imho..if your used too having your lips peeled back from acceleration..then yes..it's underpowered...if you don't mind about 8 sec's to get up on plane and cruise nicely at say 25 mph...then nope...it's plenty....your call...

If you only carry 2 people its ok. Needs 5.7s minimum. Your going to want to sell it someday and 5.0s will not sell well. With 5.0s it is called a Minum. You have a chance to not make the same mistake the original owner did.
Closest I can come is 31 Silverton with twin 5.7LX/300HP and BII. LEAPS out of the water and runs nearly 40KT. But, it takes about 3500RPM to keep the boat on plane. Whether 5.0s could do it at that RPM, I don't know. The Silverton needs to be going about 26KT to stay on plane.

Had a 32 (bay avanti 3255) with 5.7 B2 (35 loa) which of all the boats would be the closest match...and I really don;t think you'll be under powered...I'm pretty sure that was the largest power pkg for the 99 on the Maxum 30ftr...
we just purchased a 29 Sundancer, with 5.0/B3, that is the largest power pkg they offered, and while publised weight is less, in my experience I think you'll be fine.
We've also been on others boats, about the same size, with the same power, and they were fine too....
However, a sea trial would be the best way to deicde what is right for you, and make sure you invite bunch along with full tanks, etc, to really see.
Personally, I love the torque of 7.4's, and will miss them... IMO, so many people talk about horsepower on a boat, where my experience has has been having the proper torque is what really matters.
Good luck, coming off our 3700 SCR, I was very happy with Maxum, and will miss her dearly.

Don't ever mess with a bass fisherman in the South. Those guys have some serious concerns with speed!!

You got that right. The only reason the boat is there at all is they haven't figured out how to mount the trolling motors, rod holders and pedestal chair directly to the cowling of the Verados!!!
Guys I had a 30' searay. Twin merc 5.7's with bravo 3 drives...
Boat had issues getting up on plane with compnay on board. Was ok just 2 adults and 2 children.
But when adding more adults and children we had to relocate the load... Kids would have to go to the bow..put the tabs all the way down etc.... was bad... Just another reason not to invite people !!!!

Robski,
Wow, I am suprised to hear that. My 29' Larson with twin 4.3 has been loaded up with 8 Adults and children to match and still got up on plane with just using tabs.
Now that is the load I normally want but we needed to get a group home from the beach. I did have issues staying on plane if going to slow but just played with throttles and tabs never asking anyone to go one way or another. I wonder if the stepped hull has an effect.
My boat is smaller than the Maxum and Searay with 29 LOA and 10 Beam and we've never felt underpowered. Cruise is 22 knots at 3,100 or 30 at 3700. The boat will go 45 if needed. I am always on with a family of 5.

Jeff,
The boat was heavy I had the genset option it squatted real bad in the slip.. So they said the genny plus the people = VERY BAD TIME TO PLANE....
Moving the kids to the bow helped alot ....
So since then we invite no visitors ....

Sevo,
We just sold our 1998 Maxum 3000 SCR with twin 5,0L mercruisers after 3,5 years.
We never found it to be under-powered even with full load water/fuel/and family and guests. Top speed was between 29-33knots and never a problem getting up on plane. Take it for a drive - I'm sure you'll find her with enough power.

This all really helps (thx To The Max)...because my main concern is the resale in 3 or 4 years at upgrade time.
The other issue I'm faced with is whether or not to settle for stern drives and take the boat out every winter or look for direct drives (v-drives) and keep it wetslipped all year.
