Re: Outboard vs inboard weight

I/Os are heaviest, followed by Inboards and the lightest are OBs. Power to weight and trim-ability are what you really want to concentrate on for performance. Inboards have a handicap with the untrimmable drive setup, and they push down not out.<br /><br />Edit: BTW, welcome to iboats!

I believe that's for the Disposablity of them......<br />And,... Twins can be fit where Twin I/Os Wouldn't Fit......

Outboards do have a weight advantage. However, it's not that great a difference. Really only important on very small (garage size) boats. Here is another thread that goes into the other differences - The I/O vs. Outboard Thread <br /><br />Kelly Cook

Re: Outboard vs inboard weight

Other big disadvantage of inboards is that the prop is fixed and if you runaground or want to deliberately want to beach your boat you can't.<br /><br />One nice thing, like in SkiNatuque type pro boats is the engine is center mounted which helps to get the skiier up by moving all that weight forward.<br /><br />Bout 2:1 on the weight for an I/O and that weight is in a bad spot.....right on your behind where you least want it....most of the time.<br /><br />Other problem with I/O's is that you can't see the outdrive from the helm, like you can see an outboard. This is real important when trying to load onto your drive-on trailer.....when you goose it it's nice to know the engine is pointed straight ahead. Grin.<br /><br />Another problem is that you can't tell what trim position your engine is in, like for trailering, launching/loading, and beaching.<br /><br />Yeah I know they make indicators but how accruate are they and and all.<br /><br />And there are other subtle differences in corrosion, servicing, accessibility, fire, and all.<br /><br />Having had both; no way I'll have another I/O.<br /><br />HTH,<br /><br />Mark

Re: Outboard vs inboard weight

For pleasure boats 18' and bigger I/O is FAR more popular than OB. Mainly for lower purchase price and styling. Here is another thread on loading your boat at the ramp - Power loading <br /><br />Kelly
