Other than speed does the tilt and trim of the motor make a difference with anything else? Like MPG or anything like that? Also I have an older boat with a 65hp motor on it and it has a manual tilt, How do I know which knotch to set it in?

Its a 16ft Tri-Hull with a 65hp Merc.

What would really help is the size of the boat. I assume it is a fishing boat size, instead of a pleasure boat or ski boat. Tilt is what you do to get the motor out of the water.
Trim is adjusting the angle of the drive while you operate the boat. Typically you adjust the trim to an angle to help the boat plane out quicker and once you are planing, you set the angle so you zip the quickest through the water with the least drag, spray, plowing, etc. It will make your mpg better if you find the optimum for these two operations.
I can't tell you what angle will work best in your boat. It depends on the load your boat is carrying and shape of the hull, etc. Just go make test runs and see what is best. Set the motor at each angle and notice which one performs best at the two modes, getting out of the hole and staying up on the surface.
Edit added later: Since you state the tilt is manual using notches, when you find the correct notch for the different condtions, you set the motor for the kind of boating you will be doing. If you are going slow to provide large wakes for pulling a tube, you won't be planing out. Other times you'll be scooting across the lake and be planed out. You would set the motor before embarking on each kind of planned mode.
:Back to the original answer:
Good Luck and be safe!
Boating is fun, but imagine if cars were operated with no roads, lanes, signs, it would be chaos and on the water, IT IS!

With a manual tilt you will usually be better off with no tilt on the outboard as this gives you the highest MPG and optimal top end speed. As you raise the tilt you decrease the time it takes for the bow to lift out of the water and get the hull onto plane but as stated before you do lose top end speed. If using the boat to fish or cruise leave the tilt off or at lowest setting. If using the boat to waterski you might consider a slight tilt to get the boat on plane and have enough speed to get the skiier up. Happy and safe boating!

The proper tilt/trim will depend on how the boat is loaded and the conditions of the water. It does affect the handling and will make a difference with your mpg. Generally, with a power tilt, as you trim it up up the bow comes up and you go faster (less wetted surface = less drag = better mpg). Depending on the hull shape, when you tilt it up too far, the handling deteriorates and/or the prop can even start cavitating.
On a manual tilt, experiment will determine the best setting.

Yes, to get the optium performance and best gas mileage, you need to get your boat "up to plane" as soon as possible. You want to set your manual notch so that when in the water, at full speed, the plane fin on the lower shaft of the drive is horizontal level. This gives the boat the least amount of drag and best steering and gas mileage. Generally, this fin is observed tilted downward about ten degrees when you drop the lower drive in the water. As the boat comes up to speed, the front of the boat rises about ten degrees making the fin on the lower drive plane horizontially. Experiment with the different settings using full speed and you will feel and find the difference. Good Luck!

maximum in all probability a adverse connection or fuse- verify with a voltmeter or a try lamp that the motor is getting juice once you connect it in the present day. additionally -- undergo in suggestions there's a shrink activate the outdrive which kills the motor while it truly is retracted. be particular that the change leads are no longer shorted or touching one yet another or the splice/connection isn't sitting in a pool of water. The trim automobiles themselves not often fail, and could artwork whether the reservoir is empty - basically approximately truly an electric powered subject.

Yes, you get more than speed. The boat's resistance to the water will be reduced if the boat is "in trim" and planeing, resulting in more economy. You just have to experiment with it because even theough there are notches, the engine manufacturer cannot predict which type boat it will be used on, or how it's going to be loaded.

This is my 2nd year w/ power tilt, I like it. power up all the way on the throttle, cut back to 7/8's throttle, play with the "Tilt/trim" until you "Hit the sweet spot".
