Offset is 8 in run is 6ft 3 3/8in travel is 6ft 3 13/16in. How do I find the degree?

If I understand your terminology correctly, you have a triangle with a hypotenuse of 6' 3-13/16" and a side opposite the angle you wish to find with a length of 8" (and a side adjacent to the angle you wish to find with a length of 6' 3-3/8") Trigonometry says that the sine of an angle is the length of the opposite side divided by the hypotenuse. (all units must be the same, so convert everything to inches)
So sine (angle) = 8/(6 * 12 + 3 + 13/16)
sine (angle = 8/(75.8125)
sine(angle) = .105523
angle = arc-sine(.105523)
angle = 6.0573 degrees (from tables, calculator, computer etc)

Motor over revving

Firts thing I would look at is the hub in the propeller. It may be spun. Check that by removing it and looking at the back side for for burnt rubber or smell of burnt rubber. You can also (with the engine off and spark plug wires removed\ignition disabled) put the engine in forward gear and try and turn the prop counter clockwise. If the prop turns I would suspect the hub will need replaced. any prop rebuilding company can do this for around 50.00 or less. If the prop doesnt turn, You may need to loook into the lower unit internally and inspect the clutch\gears, etc.. Those can be suspect and usually due to shift cable issues, water intrusion, lack of oil changes etc.. Hope this helps.. Let me know if you need more assistance.

It's difficult to determine witch trim buttons effect the props. The only way to do this is durring flight. At low power, since you are working with 4 axis, each set of 2 buttons will effect the rotational speed of 1 motor. Typicaly in this set up, the left stick will control power and yaw(up and rotation left and right), while the right stick controls direction and pitch.(forward/reverse and bank left or right) Here is what I think you need. The left side bottom butons, control horizontal control. If you take off and notice the helo going to the left(banking, not turning) click the right button to attain horizontal stability. If you notice it is going slightly forward click the bottom button on the right side of the left stick. The same can be said with the axis control on the right stick. I hope to see this aircraft on youtube, as there is a shortage of these flying stabile anywere. good luck.

15hp power old mdel bt in good cond.if run on full the engen dont want to push the vessel like before what must i do ?

If rev-ving up as it idles the same and can get you moving normally in low speed when in gear...then increase the speed, always under load (in the water) and if you cannot get the same thrust most common proplem would be the propeller (prop) spinning hub slipping problems to plain prop damage/wear and tear.

If you are convinced it is not an engine problem take the prop to your local marine dealer that has a good parts manager. Bring all info (model/serial number). If you are lucky it is a torn or loose hub.

Marine dealerships have a deal w/ prop machine shops that usually come in once or twice a week. Depending on the business the business or condition of the propeller they might offer to sell you a new one (may not be in stock) usually 2 day shipping. That is another option. I have seen 15 hp steel props (usually heavy use in salt water) I would ask for the parts MANAGER.

Removing a prop from a small outboard: Use needle nosed pliers and straighten the key evenly ...any type of plyer remove key ...may have to use regular pliars for leverage. Use a socket wrench to undo the the nut. Use a crescent wrench at an angle if not available. Remove prop...If stuck spray w/ lubricant and let stand overnight. Use a hammer and chisel while revolving the prop a few times. if it does not free itself quickly (Do not desroy your prop shaft).

I mostly know small OMC Evinrude/Johnson outboards from the 40's through late 80's....Always include a model number and at least the make of the brand. I have no deal w/ as an expert but just offering free advice hopefully someone helps me.

Key lock ignition won't turn. Does it have to do anything with the programming? or just mechanical failure? This is for a 2005 Dodge Durango. key ignition cylnder is stuck and won't turn.

Programming won't effect if it turns or not.

The most common problem is when there is feedback pressure from the tire against a curb, up hill, etc., and that causes the steering lock to bind the key cylinder. The solution for that is to try pushing both ways on the steering wheel, as you try to turn the key, to relieve the pressure.

The second most common is wear on the key, so it helps to jiggle the key side to side, up and down, etc. as you try to turn it.

Try turning the key upside down, using the spare, etc.

As an act of desperation, you could try putting the key in, and gently tapping on it with a piece of wood or the handle of a hammer. They are beginning to make ignition locks with tumblers spring operated, at right angles to the key, and they are very easily bound up by friction, because the springs are so small and weak. This was a very common problem with the Ford Focus, and I believe Dodge picked up the same bad design.

Boat won't plane idles fine runs with throttle open without hesitating doesn't build up speed

Check your prop hub. If you have a larger motor there are rubber bushings in the hub which can slip. This is a safety feature like shear pins. You may need to rebush the prop.

You also need the proper length motor for your transom. And you need enough power to overcome the drag and weight of a loaded boat. Check and see if the angle settings for the locking pin will provide an upward thrust to the hull and not plow the hull down.

What role does the trim tab on an outboard play as far as handling and hard steering, and how do you adjust it?

If you are talking about the small tab under the cav. plate.Its job is to counteract the effect that the prop has on steering.Because the props. spin in one direction,they create a sideways pull on the motor due to the prop biting into the water and trying to pull all with it.2 motors on the 1 boat often have a different gearbox fitted,and one will spin in the opposite direction and this counteracts torque steer.To adjust yours,work out where you drive the boat most.Speed etc.Higher speeds have more effect.If it pulls right,adjust it left.One bit at a time.I think yours will have an allen key or hex screw above the tab.Loosen it,move the tab.Takes only minutes.I hope this helps

Harman Kardon Go + Play Portable Speaker Keeps Shutting Off

I just had this exact problem. I'm using an ipod mini. I solved it by docking the ipod firmly at the angle
the dock is at and have the ipod at an angle, not flat. I put the plastic and rubber adapter for the mini as instructed and also placed the rubber adapter for the nano upside down to keep
the ipod propped at an angle. (Also can use something similar to keep ipod propped up at an angle)
Took a while when I first used to figure out how the dock worked. The dock is a little weird how it is hinged to go from an angle to flat. Nothing in the instructions about this. By putting the ipod flat it would still have a connection to charge and play but the power shuts off every 10 minutes. I spent a whole night having it shut off every 10 minutes. This drives me crazy when systems have features like that which always seems to cause more problems (just my humble opinion)
By having the ipod at an angle I'm currently just now having it run an hour and 20 minutes and counting with no shut offs,(fingers crossed) but so far so good.
Saw on the internet that if the ipod is not connected firmly the system has an auto shut down. I think the ipod's weight propped at an angle keeps the connection firm. Also some said they want to see the ipod display, there you go!!!! This seems to be working so far for me, may be worth a try...I was about to return mine but I love the sound so I'm keeping mine now!!!! Works fine. Happy camper again.
Please reply if this works for anyone it worked for me.

Wide-Angle Lense Fuzziness

That's completely normal for those cheap wide angle add on lenses. There good for a little fun but nothing serious. I bought the lens kit for the Kodak DC3400, probably the exact same lens. The telephoto in that kit was actually pretty reasonable though.
