two motors on one boat
I am new to boating and am trying to add a small 6 hp outboard to my fishing
boat for trolling. Can I simply move my existing 30hp over 6 inches to make room on the transome ? or is it crutial that this main motor be centered ? Thanks John |

Thanks John I have no idea what the boat would handle like on plane with the engine off-center, but I don't think I'd want to find out. Surely you'd be fighting the steering constantly. I see *many* boats with trolling motors in the Chesapeake Bay. I've *never* seen one with the main engine in a position other than center. -- John H "All decisions are the result of binary thinking." |

Thanks John ================================= I've never thought of trying this, but I have had one of the engines shut down on a twin screw boat and suddenly find myself going in a circle. Then, fighting the wheel till I could get home and fix the problem. I use a swing up bracket on my 21 footer for a 4 HP outboard and it workds great. Also, keeps the kicker out of the water while on plane. Happy boating, Norm |

Not sure of the price, but have you seen the trolling motors that mount
to the outboard and swing down. You use your main engine steering wheel to steer them... never owned one... just see them all over the place. JJ wrote: Thanks for the help. I guess the easy way out was not the answer. I will look into getting a transom bracket. John |

krause
you are the last person who should be giving people advice on boats. I know,, I know,,, you used to own the largest OMC dealership in America. hmmmm,, but keep your opinions to yourself. If you want to lie,, if you want to brag about your dysfunctional family,, the 3 wives, the 3rd 20 years your junior and dumb as a shrimp. The children leaving you etc etc etc,, krause you can brag that all day long,, but don't give anyone advice on a boat, it is just too risky. You off your meds today by the way???/?? You have made some really stupid statements. I mean ,, make it center,, then don't make it center,, krause ,,, you mixing up those meds again/?? The little woman mixing hers in with yours?? You mixing that viagra in with your heart and liver pills again? you really shouldn't , you know that makes your nose grow,,, hmmmmmm but you have no problem doing that on your own.....

Thanks John It's important that the main outboard on an outboard boat be centered so as to avoid steering and balance problems. A main motor mounted off center will not steer the boat in a straight line. You'd be better off finding and mounting a transom bracket for the smaller motor. If you do, make sure the bracket allows you to tip the trolling motor up out of the water completely. -- Bush and the NeoConvicts who control him are destroying the once-great United States. |

Thanks John You should try it, oft the simplest solution does turn out to be the best & given it will cost you nothing; try it first & see. Given your main motor is 30Hp I'm guessing the boat isn't too big (no offense intended) & in smaller boats having the OB offset while not exactly common is still seen regularly.

They're not too concerned with "convention" at the marinas, just outcomes:-) The Whaler catamaran brands used to be sold with a single offset OB. If your OB is tiller steered or wheel with you to one side, this means you're biasing your weight to one side in the boat anyway, indeed you'll notice that this means to traverse a straight course you actually need to have the OB at a slight angle anyway to counteract the weight bias of you to one side, the engine torque & the prop water wheel effect. So experienced boaters who want to actually "use" a boat & have it track easily, or want to stand & do work related things without their weight upsetting the track too much often move the OB slightly to one side (the engine must remain vertical, don't just tilt it sideways) How much depends very much on the weight bias to be counteracted, the boats beam, size, speed etc. However be a real boatie JJ & experiment with it you'll be astounded how much extra performance you can get out of a small boat if the motor can actually be pushing directly forward & fun you'll have doing it:-) I read the thread with some real disappointment because ........................... well because as usual parody Harry (the last one) seems to actually be a boater & actually know about boats unlike the original Krause who is just a non boating liar, imagine that??? with the boating experience Krause claims & he's totally unaware of offset OBs????

Unless the two motors are of equal horsepower and mounted as twins,
there is no reason why you would move the main motor to anyplace other than directly on centerline. I can't imagine what a boat would be like to steer if it is up on plane with the main motor pushing from one side. I have never seen it done and am not likely to, either. Ca[t. Jeff |

One of my big treats in Vietnam was to visit the 'Aussies' at their base in Bien Hoa, just outside Saigon. They were a great group and always willing to unload a few beers on us 'Yanks' at their officers' club. They also had a very small Post Exchange (PX), but it carried the best selection of cameras and lenses to be found anywhere outside Japan. I flew once as an observer on a US Air Force plane which was supporting (marking targets) for an Australian B-57 Canberra bomber. We were marking a very small (5m X 5m) shack which was a suspected ammunition storage site for the Viet Cong. The bomber dropped three bombs. The second one landed dead center on that shed, and the resulting explosion was astounding. Their accuracy was unreal. Great group of folks, those 'Aussies'. We always loved visiting or working with them. Of course, the Canadians are great fun to visit also! -- John H "All decisions are the result of binary thinking." |

Depends on the boat and configuration of its bottom, but I would bet you could get away with it no problem. Especially just six inches. Many commercial oystermen and shrimpers in my area offset the outboards on their skiffs. And literally tens of thousands of auxilliary sailboats mount their outboards on one side or the other. Point being, it can be done and it's commonly done. Just depends on your particular boat's bottom. If you have any sort of strakes and/or keel, I'd give it a try. If it works,and it probably will, you'll have a boat with less list than otherwise. One BIG caveat.... make absolutely sure the two props will always remain clear of each other. Rick |
I am going to try a kicker plate that will hold my small trolling motor to
one side and leave the main motor in the center. Thanks again for all the feedback. -- John |

Offset motors are NOT unusual, except maybe on white fiberglass bathtubs with outboards on the back. Dive boats often have offset motors to make room for a dive door next to the motor that opens onto a swim platform. As an example, see the first link below. Boats by this designer range in size from 18' to 24' and are very commonly run with an offset main motor, with or without a kicker. The designer publishes a formula for how much to raise the motor versus how far you offset it: http://www.fishyfish.com/bobbruce/index.html (the main is WAY offset on this one, 24-1/2' LOA) http://www.alaska.net/~tolmanskiffs (the designer's web site) http://www.fishyfish.com/tolmanskiff.html (several other examples) Brian "Harry Krause" wrote in message ...

The boats in the links that I gave have minor fairbody and side strakes, in
addition to their 8 to 12 degree deadrise (depends on model). They all work hunky dory with offset mains. The only thing some owners have said is that if they offset too far, that they get more cavitation turning in one direction compared to the other as you might guess. They ALL say (in spite of that Kraus asshole) that the boats operate fine and that you can't tell the motor's offset by how the boat handles. They probably lose a little efficiency since the boat is probably traveling at an ever-so-slight crab angle when motoring straight ahead (due to the offset line of thrust). But if so, it's not measurable. These boats get good mileage due to their light weight and modest deadrise regardless. They are used offshore in Alaska and have 'seen it all' when it comes to ocean weather/waves/swells, and that includes with an offset main. As I mentioned, the use of an offset main is very common on these. It's also common on many of the aluminum boats around here, and for the same reason. I suppose Krause knows all about commercial fishing and letting nets out the back, dive doors, etc right? Yeah, right. I don't know where Kraus is, but he sure ain't from around here and he sure does NOT know it all. That's for damn sure. I've only just 'met' him and I'm adding him to my 'blocked' list already. Not worth responding to. What a dumbass. Brian D "Short Wave Sportfishing" wrote in message ...

My main concern with the original post was exactly what you mentioned - crabbing while under way. Thinking about it though, I can see how it would work on these boats with the moderate deadrise. I also am curious about chine walking at speed. I guess the real question is why the boat isn't built a little wider to accommodate the door? Even in the standard configuration, it would seem to me that there is plenty of room on the starboard side of the boat to put the kicker and leave enough room for the door on the port. The only experience I have with dive boats have mostly been boats with open sterns like Privateers. Later, Tom |
