Howdy,

I am looking at a nice 25' center console fishing boat that weighs 3700
pounds dry and without power. Will a Suzuki 250 be enough get up and go or
will a pair of 150s be necessary? I think 3700 is pretty light for a 25'
CC
compared to a Grady or Mako. Thoughts? My piggy bank would like to say
single.

The principle reason to go with twins is redundancy. Your piggy bank
and your level of comfort with losing either some or *all* power will
have to come to terms.....

Another major reason for twins is maneuverability.


Twin outboards are usually placed so close together that there is very
little benefit in the minute amount of asymmetrical thrust that can be
produced.

That's been beat to death and lost.

I agree. With outboards or I/Os it just doesn't make that much
difference. With inboards it's a whole different story.

I also agree that redundancy is not that big an issue with inshore or
near shore boating. However, if you boat near dangerous surf, tide
rips or breaking inlets I'd vote for twins no matter how far out you
go.

My twins were on boats with I/O's. I could pivot either of them on a dime
and could easily stern in when docking. My single drives (I/O's also) could
not and my ability to maneuver in reverse was/is a bit challenging. I could
not imagine trying to stern in with an single I/O.

If there is in fact no advantage in maneuverability between single and twin
outboards (vs. when comparing with I/O's or inboards) perhaps it is due to
where the drives sit in relationship to the pivot point of the boat and not
the space between the drives.



There is a world of difference between close quarter maneuverability
with an I/O and a inboard. You really should be able to turn and/or
stern in that small runabout easily. You probably forgot how to use a
single I/O after using twins. You need to have someone review the
basics and find out how easy it is.

The fact that the I/O pivots and you don't need to rely on the water
flowing past the rudder to maneuver makes a single I/O runabout a very
easy boat to maneuver forward or in reverse. If someone is having
trouble, they need to have someone teach them the basics.

Bad fuel problems will still leave you stranded.

Let's see...listen to Gene and Wayne, or listen to JimH??

That can happen if you have a single fuel tank. The best dual engine
setup also has dual tanks and filters.

I'm now on my second single engine I/O, both in the 24 to 27 ft range.
I've had no issues backing them in as long as there are no cross wind
or cross current issues. It does take some practice to anticipate how
the boat will react to combinations of steering and throttle.

outboards (vs. when comparing with I/O's or inboards) perhaps it is due to
where the drives sit in relationship to the pivot point of the boat and not
the space between the drives.

Space between the drives and size of props makes a very big
difference. The more distance between props, the greater the turning
moment on the boat.
