Will fishing boat makers power their boats with I/Os? Do their customers want the I/Os instead of O/Bs?

For freshwater, maybe. At some point freshwater buyers are going to get fed up with OB prices. I don't think the saltwater market is so price sensitive. So don't expect any real change there.

Possibly the biggest impact on the inboard vs OB situtation will be future alternative fuels. It's possible (not necessarily likely) that one type won't be able to make the change, then there could be a tidal wave ...

Close to me, I/O's are very popular on both Carolina Classic and Albemarle boats.

We like the unobstructed transoms plus the option of jack shaft diesel and gas sterndrives.

The waters here are famous for 4-5 waves stacked up so engine weight a midship is beneficial.

You can't beat ride and efficiency of a stern drive.

Just a side note to another thread about Brunswick boats having only Mercury/Mercuiser packages.

Albemarle boats which is one of Brunswick's fishing boat lines can be had with either Volvo or Mercruiser gas AND diesel options.

Are there other brands with gas engines that are not Merc O/B or MerCruiser I/O?

I happen to like I-Os but here in salt water people who run outboards think you're nuts of you have an I-O because of the maintenance issues. I think a fishing boat will always sell better and retain its value more (at least in coastal regions) than an I-O unless it was one with the Volvo OSI system or Merc Seacore

From a 11/6/02 thread...

"25' 7" lenght, 8' 6" beam, 7,100 lb boat plus or minus 100 lbs. boat with a small cabin (not a mid-cabin). Same boat for both engines.

Added retail price for each and 50 hours of use at each boats best cruising speed for milage together to get the year's spread. No allowance for repairs, tune-ups, oil changes. Just retail price and fuel usage.

Figured the fuel price at $3 per gal.

THe O/B cruised slightly faster at its best milage speed, 27.7 mph. I/O was slower at 24 mph. But, that is the data in this comparison and either may be thought of as a typical cruising speed for this boat.

The O/B went 185 miles farther at its 50 hours of use.

The I/O, however, was the $18,599 cheaper way to go."

I/O $18,599 cheaper.

I/O $18,599 cheaper than the O/B.

That is $18,599 cheaper.

Another note from experience is that I/O's have more torque at lower RPM's and are easier to maintain running attitude and planing speeds in the big stuff, 4-6 waves.

Comparing the two boats that I have is that the sterndrive can maintain much lower planing speeds. The sterndrive is happy at 2500 to 3000 and 15 mph on plane with tabs down, while the outboard really doesn't seem happy until 3600 - 4000 rpm and 20 mph.

Obviously the two boats are not identical but the outboard boat is much less responsive to trim tabs also. I guess if you think about it, the pivot point is much lower on a sterndrive than an outboard. That may have something to do with it. I think the duo=prop on the sterndrive is a contributing factor also which leads to my next question....

Why does Yamaha not have duo-prop options on the 250 - 350 hp outboards?

They had it on other big O/Bs in the past and it did not sell well enough.

And they did add it to their I/O drives that they sell in Europe.

The I/O, however, was the $18,599 cheaper way to go.

With $18,599 savings, you could throw away the I/O every three years and be about even with the O/B guy in terms of money shelled out.
