On Fri, 5 Oct 2007 14:18:47 -0400, Lance Osojnicki penned the following well considered thoughts to the readers of rec.boats: 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. 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. I have never had twins on anything, Backing down with a io is a no problem at all. just like backing down with a outboard. Capt Jack R.. |
