Hey, Ben. I'm red headed. No, just kidding.
The Verado's are really great motors, and the supercharger should make them plenty torquey. My problem with the Verado is that the dealer's going to charge you $3000 for "setup" plus everything high tech is so expensive. You've got the fly by wire SmartDrive throttle/gearshift. You've also got the $1000m multi-function tachometer with built in flowmeters and other things. I've tried to read about them online, but it would take an electrical engineer to figure out how to hook up everything. And we all know that high tech comes at a price. Thousand here, thousand there. Before long, you've spent a small fortune on nothing functional. At least their integral power steering is better priced than SeaStar's power steering unit.
I heard great things about the Suzuki's at the boat show earlier this year, especially the 140 hp model. But, with their 150 hp, you get another 50 cubic inches. The 150 is heavier, but cubic inches are hard to overcome--and I'd go with it. And, Suzuki's are not geared like a bass boat engine--2.5:1 is a pretty low ratio that'd be good on a party barge.
On the negative side, I've just heard complaints about the prices of Suzuki parts and they lack the dealer base of the "big 3." There again, maybe part purchases will seldom be needed.
It'll be nice to see how the new Mercury 150 hp works out. On paper, it looks great. You can hook it up high tech or with old style cables and gauges. It also can be bought for under $10K. I'm old school, and don't really need all the new fangled stuff on an inland lake. When my gas gauge gets low, I just fill it up.
Heck, I'm so old school, I only carry a cell phone so I can call my neighbors to tow me in if my pontoon boat breaks down. With a cell phone, it's hard to hide on the lake.
