Inboard outboard versus Inboard Damage

[boatbuddy]

We are thinking about getting a SV 211.

Our current boat is an I/O.
We use to have a 34 foot Searay with twin Inboards but never hit any underwater objects with it.

What kind of problems can you have if you hit something underwater with the SV211 or any inboard

Is it more expensive to repair an Inboard than and I/O - hitting the same object

I have only had a few knicks on our current I/O propeller - never had any serious damage. (Actually these knicks were done by other family members driving the boat!!)

Can this small knicks on an Inboard cause shaft damage.

Just trying to figure out how careful one needs to be?

I am used to the tilt option on the I/O

RE: Inboard outboard versus Inboard Damage

1. I think The 211 will draw less water than an I/O minimizing th benefits of a tilt option. Someone here should be able to give the exact number but I bet there is a foot Difference

2. You should remove driving privilages to those responsible for those nicks.

I'm certainly no expert on CC but I was under the impression the brass prop's were designed to be somewhat soft and take minor dings without damaging the shaft. Both my brother and father in law damaged their boats last year at low lake level. One hit a stump and the other backed off the trailer onto a chunk of concrete. Both required shaft replacement and/or prop replacement.

I owned an I/O prior to my inboard and would never go back to an I/O. Both repairs listed above exceeded 1200.00. It really depends on the object, speed, and experience of the boat operator. I've banged my inboard a few times on under water objects but not under any speed.

boatbuddy, sounds like your trying to talk yourself out of this purchase Yellow_Flash_Colorz: .

What it costs to repair depends up what your tear out. Both can be very expensive. However, it is generally more expensive to repair/replace and outdrive than it is components of an inboard. More going on with I/O. Not just a propeller and shaft, but you have the housing, the gears and shafts, steering gimbals, etc.

In it's worst case, you have about 2K in damages with an inboard or vdrive. Fins, shaft, prop, rudder, and the shaft guide. A single outdrive costs more than that.


NHcross, the fact that a boat has an I/O has little to do with the draft of the boat. Rather it is a factor of weight, hull shape, width, and weight. While it is true that most VHull I/O runabouts have a deeper draft than most inboards, there are plenty of low profile fairly flat bottom I/Os with relatively shallow drafts.

H20, most modern inboards have Nibral props, not brass. Nibral is a composite metal. If I remember correctly, Nibral is fairly soft so that it bends easily, but has a high sheer strength, so that it does not break easily. I could be wrong, but I beleive this will provide greater protection to the transmission than it will for the shaft. Generally, Stainless props aren't used on inboards because they protect neither the shaft nor the transmission. BKH

boatbuddy, i asked this same question when i got into inboards. the thing was that i was already determined to buy a tournament ski boat. i asked because i like to know what i'm getting into. BK makes some good points, just make sure you know the reason why you want to go in the direction of an inboard. don't let some rich "johny-come-lately who's kid has been wakeboarding for a year and can get a whole 14 inches over the wake" tell you that you've got to own the latest 60K dollar boat like he does.

i have a few dings in my prop and was looking for someone to touch it up. my local marina sent it somewhere and they quoted 230$. they said it was reasonable because a new one would cost 700$. i semi-politley informed them that Overtons sells them for 280$ brand new.

boatbuddy, you probably wont regret buying a inboard, but make sure you constantly increase your boat knowledge on web sites such as this one or CorrectCraftfan.com.

Nibral? Never heard that one but I'm learning more and more about inboard as I go. This is an awesome site. I've been around inboards for 15 plus years and finally got the stones to purchase one. I dont think any one would be disappointed with a CC purchase.

Thanks for the info.

Nibral - NIckel, BRonze, ALuminum, i think...

[bkhallpass]

Yes, Nickel, Bronze, Aluminum. I used the term composite, which is incorrect. Nibral is an alloy of the three metals. BKH

I have had my prop reworked a number of times from oops.

The first was whne the lake level was way high, and we launched at a ramp that has a pier between the two ramps. The lake level was so high, the pier was under water. it turned out the pier was directly behind the trailer and I backed over the pier with the boat. Bent the prop. $100 repair to the prop.

The next time was on a limestone lake. I drifted too close to the shore where the prop hit hit the limestone and bent the prop. $100 repair.

The third and most recent time, I was on a rock shored lake, where the shore looked sandy so i tried to beach the boat, but I hit the rocks instead. $100 repair to the prop.

Now my prop is getting thin, and I might have about 2-3 more repairs in it. On a good note, I did have the shop reduce the pitch a bit and add some more cup to the prop the last time and now it pulls harder and even has a higher top speed than the original pitch/cupped prop did.

I would say that in most of those cases, I might have prevented the damage if I had a i/o since I would have probably had the engine trimmed way up in those circium stances. But given the choice again, I would still get an inboard. All of my damages have happened at idle speeds.

I've owned both I/O and inboard boats. From a maintenance perspective, I have found the inboards to be far easier and less expensive. Had the seals on my outdrive fail twice. Only way you know this is when you hear the bearings fail.

IO boats can be much more versatile, but if you have narrowed down what you want to do on the water to towed water sports, it doesn't get any better than a CC direct drive.
