Re: What an IO is best at

The kids and grandkids and their friends like to swim out in the middle of the lake, so I kinda sorta have to just sit sometimes, thus must consider the entire family in the boat config equation. Easier reboarding with a full platform, much easier on my mind. So, I will pile that on to the I/O is best at, uh, pile.

When I think of a boat, even today, my mind puts up an OB profile pic for me. I really like our I/O platform boat but my favorite is still the OB, soft spot in my head maybe. But the I/O is best at meeting this family's requirements for good boating experience, as the platform is integral to their expectations now when they think of boating.

Ok, I have to editorialize just a bit, so here goes...
YES, just sitting and bobbing (while NOT fishing) in a lake 500 miles from any ocean IS a fun part of the boating experience for many... :rockon:

The 595 O/BSC is rated for 300HP, and will actually handle some rougher conditions, wheras the Checkmate will not be as proficient.

It's definitely nice and the they have a bow rider version too I see. Most companies that make outboard powered runabouts limit them to ridiculously low HP like 150HP for a 19'er. Good to see Champion doesn't have their heads up their butts, and will let you put some real power on the boat. At 2300lbs I'm thinking they would run really good with a 250 Mercury Optimax or Yamaha SHO.

Do they have a pad?

Re: What an IO is best at

We do like to float and swim. We spend a lot of time tubing. Kids love it best. I sit on the sunpad with my feet on the swimplatform while putting lifejackets on the kids. I sit the tubes on the swim platform and can put the kids in or on the tube and just slide it into the water. The platform is perfect for watersport because it gives a stageing place, plus no big motor in the way. The swim platform also keeps the kids away from the drive. My wife likes the sunpad , I like the bimini.

Just get an I/O with a O/B kicker and everyone is happy! :)

You see that for two reasons:

1. Cost: I/O owners go into sticker shock when they see the price of a 225 HP outboard, let alone one with a boat attached.

2. You don't need that much HP on an outboard powered boat because of the HP to weight ratio. A 21' boat with 175 HP outboard would run circles around an equally sized boat with a 4.3 (220HP) Mercrusier

Re: What an IO is best at

Kidding aside, one of my observations about the different boats and styles fitting different circumstances, is that the lake boaters tend to do a lot more swimming from the boat, typically anchored, and thus use it (the whole boat) as a swim platform, than do the salties. Perhaps the deep south salties do a lot of anchoring and swimming, too, but what I see is people beaching the boats when they want to swim, and not being tied to the boat as a base. We have soft beaches instead of rock sides which lends itself to this, so we don't really need the platform, but do need the shallow drive of the OB. When you lakers are anchored in more than 4' of water, you can use that platform as a "beach." Plus we have a lot of things that nibble, chew and sting down there, so some folks don't like being in the water; not so in the lake.

Of course that's not to say there aren't exceptions; I've seen the sandbar parties in lakes (though more often a raft-up in a cove) and plenty of people anchor and swim from the boat in the rivers, bays and off the ocean beach here. But there are factors like that which make the preferences of different styles in different waters.

I don't buy that at all. Here are some numbers for two similar boats(from Monterey website)

217 Blackfin with 175hp Verado Outboard. WOT speed = 44-48 mph.
204 FS with 220 hp Mercruiser(4.3L) sterndrive WOT speed = 46-50

Dry weights of boats are within 100lbs. of each other. Lengths are within 1 foot of each other. So I can't see the OB powered boat even being able to catch the sterndrive boat to make an attempt at running circles around it.
Monterey's numbers are spot on, as our 204FS hits the numbers exactly as stated with our V8 sterndrive.

I agree on point number 1, outboards are expensive. That's no reason not to offer more power though.

Going to have to disagree on point 2.

I've been a outboard guy and a bass boat guy my whole life so I know and understand outboards. My Stingray is the first I/O I've ever owned. Most 175 Outboards are small blocks and don't have a lot of low end torque. This goes for the Mercurys, Yamahas, and Evinrudes. That changes when you hit the 200HP area as they become the big block motors with much wider power bands and good low end torque.

For instance Stingray offers my boat in an outboard model (called the 194LX) but the biggest motor you can get is a 150. With the 150 it is 4MPH slower up top and .3 seconds slower to 30MPH than the 220HP 4.3L MPI model. Giving the outboard another 25HP is not going to make it run circles around the I/O boat. The outboard does beat the I/O to 20MPH by .25 seconds due to the fact its lower weight and higher negative trim angle allows it to plane the boat faster, but after that it's all I/O. All those numbers come from Mercury Boat House Bulletins.

http://www.stingrayboats.com/data/documents/boat_house_bulletins/198LX_Merc_4-3-MPI_2-12-2013.pdf

http://www.stingrayboats.com/data/documents/boat_house_bulletins/194lx_150hp_032113.pdf

Now put a 200 Mercury Optimax Pro XS or Yamaha SHO on the 194LX and I bet those numbers change drastically giving every category to the outboard. I would have bought the 194LX if Stingray had of rated it for a 200HP motor. When I spoke to Stingray about it they said the 150HP was the highest HP outboard they sold so that's what they rated it at. I think that's crap and the real answer goes back to your point number 1 and they wanted to keep the max package price at a certain point.

Humm....you take the heaviest, doggiest, 4 cylinder outboard on the market. You bolt it on a hull that is 1' longer, #360 heavier and has 1 degree more deadrise than the v8 powered comparison and it's "similar"?

Bolt a 175 HP Etec or a Yammie 175 SHO on your 204 FS hull and see what happens.

Re: What an IO is best at

Errr, I did not compare it to my V8. Read what I posted. I used the same analogy as you did. 175hp outboard, compared to a 225hp I/O in the same hull.

Show me some data of new boats that back up your claim, and I will listen.

Re: What an IO is best at

We are lake boaters and I don't beach this boat because I don't want to wear on the gelcoat. We anchor at the bow with a bungee line and pull the back close to shore to tie off. You can see it in my avatar. That is most of our lake time. We will also sit on the lake just floating and watch the cliff jumpers or when stopping for lunch. A full length platform is a very used space. An OB would really be in the way for us.

Around here that is the normal setup unless you are just a diehard fisherman. They run boats like the Ranger style but they are probably only 10% of the boats on the lake if that.

Re: What an IO is best at

As far as which setup is best, there is no right answer. Some guys like IO's, some folks like OB's. Some people want a pure ski boat. My last 2 boats have been IO's. I like them just fine. I wouldn't pass on a boat if it had an OB as long as the setup fit what I wanted to do. Any of the setups will get you out on the water and that's where we all want to be.

Re: What an IO is best at

I've had both OB and now I/O...grew up with I/O's and sailing...We (lake boaters exclusively) do tend to use our boats for lounging, while my OB had the 2 helms, 3-person bench and bow cushions, and the I/O has that plus the sunpad I feel it adds a certain amount of lounging space for the wife and kids while anchored/beached (yes I beach, always have and always will)...My OB boat had 2 cup holders (aftermarket); whereas the I/O has 8 (factory) so clearly that's a sign I should be lounging and drinking more?

My kids do not sit still (unless sleeping, hello Benadryl)...so the Sunpad is for us to watch the kids while they swim...I meant that more as an over dramatized general cry about considering the children, not necessarily in defense of either OB vs. I/O...sunpad/swim-deck/splashwell.

Has anyone mentioned noise? I know my Mercury 200 Blackmax was LOUD, but I had the exhaust baffle removed and drilled!! So, the I/O (at least in my situation) should be much, much quieter!?

My 5.7l under the sunpad is quieter than my 2.5l under the doghouse.
