Set Boat How do you know where to set the trim on an inboard boat? And.....?
how long would it take to crack a valve cover by not adjusting the trim right? Would it be right away or 1 hr of running time?
Outboard engines above about 30 hp are generally equipped with power tilt and trim. There are usually two hydraulic pistons set into the engine bracket, the "trim" part of the system, used to adjust the angle of the engine when under power. There is also a single hydraulic rod connected higher on the engine, the "tilt" part of the system, which is used to tilt it up clear of the water. In shallow water, tilting up into this higher range for slow speed operations is OK.
Trim Angle Depends on Boat Speed and Water and Weather Conditions The proper trim angle for outboard engines depends on the speed and the conditions. Trimming the engine will adjust the angle at which the boat rides through the water. In smooth water, a GPS makes finding the best angle easy. Just trim the engine all the way down, set the power to your normal cruise setting, and start trimming up slowly in small increments. The speed will increase as the hull finds the most efficient trim angle, and when you have gone too far, it will start to decrease again. Other bad things may happen when you go to far, such as excessive cavitation, porpoising, or your friend jumping up and down on the bow.
Boats with V Hulls May Ride Better With a Little More Trim I have found that many V-hull boats ride better in choppy water with the engine trimmed in a bit from the most efficient angle. With the engine trimmed in, the hull rides flatter over the water, and it breaks through the water further forward, where the hull has a sharper deadrise angle. Also, if the bow of the boat bounces up and down a bit, it doesn't affect passengers sitting further back as much as if the center of the boat bounces up and down on the same chop.
When riding across the wind in a chop, you are likely to get wet, especially if you are on the upwind side of the boat. You can usually get a more dry, comfortable ride by trimming the engine above the optimal angle. The bow of the boat rides very high, and the spray is thrown behind you. It will be a more bouncy ride than with the engine trimmed further in, but at least you'll be dry.
On boats equipped with trim tabs, you have the additional option of trimming the engine to the optimal angle and then using the trim tabs to lower the downwind side of the boat and raise the upwind side.
When riding downwind in a chop, I like to keep the engine trimmed out enough to keep the bow pretty high. You never know when one of those waves is going to be a bit bigger than it looked, and if you're keeping the bow of the boat down, you might just dive right through.
Best Trim in Larger Waves In large waves, the same general rules apply as with driving a boat in chop, except that you need to be cautious. The best plan is, just don't drive fast if the waves get large. I don't find it fun, and it's hard on the equipment. It is also a good way to drive a boat through a wave when going upwind or downwind, and a good way to capsize going across the wind.
In large waves, I want the boat to be controllable, and I want it to plane at slow speeds. For both those reasons, it is best to trim the engine down far enough to help keep the boat level and on plane at slower speeds. In some cases, that might mean all the way down past vertical.
Hydraulic Systems Require Little Maintenance Hydraulic tilt and trim systems are very low maintenance items. There are switches, hydraulic pressure pump and lines, cylinders, shafts, seals and valves, and any of them can fail or be broken, but if you keep them clean and use them once a month or more, they can last for years. When trailering a boat, be sure to lock the engine in the tilted position with the manufacturer's lock or some other mechanical lock. Bouncing down the road is hard on the hydraulic seals, and the way the engine can bounce up and down if not properly restrained can also stress the transom of the boat.
One last note for anyone who is still trying to figure out all the terms used. Although this page is about hydraulic power tilt and trim systems on outboard engines, I also mentioned hydraulic trim tabs, which are a completely separate piece of equipment. They are hinged plates mounted on the bottom of the transom of a boat, with hydraulic pistons to move them up and down. They can push the bow of the boat down on either side by deflecting water downward on the opposite side.
Fishing Boats - 3 Things To Learn Before You Buy One
Some anglers prefer to wade in the water to catch their fish, whereas others prefer to go into the deeper waters in a fishing boat. Wading in the water may give some fishermen a high because of their proximity to the fish that they are going to catch, but it is not always safe to do so, and staying in a boat to catch your booty is a much better bet. Prior to setting out on a fishing trip it is always safe to make sure that your boat is in good working condition and will not suddenly break down in the middle of the water and leave you stranded. Selecting a boat should also be done according to your needs and should be given a lot of time and thought and not something that you should do in haste.
1. A sports boat as your choice While thinking of buying a boat you should keep in mind the safety and comfort of those who will be on it. Sports boats offer both safety and comfort and are very popular as they can be used not only for sporting purposes but also for other activities too or for just enjoying the time spent on water. There are many kinds of water sports and you should take part in various activities so that the rest of your family can also enjoy themselves while you are out on a fishing expedition. So consider wake boarding and skiing apart from fishing for your dinner.
2. The different kinds of boats to choose from Fishing boats that are made for shallow water and can hold only two people are called Skiffs. These boats are made for smaller areas of water and can be operated easily in the water. Skiffs are used the world over for rivers and small lakes.
Light tackle boats can be used for any kind of fishing and can accommodate 4 people on it. The main benefit is that the fishermen can move around on the boat as there is enough space. Some kinds of catch require the fishermen to walk around on the deck and this boat has enough space for movement. Being bigger it is also sturdier for bigger catch and is more comfortable for the fishermen to maneuver around.
An offshore boat is required for a deep sea fishing expedition. These offshore boats are around 35 to 45 feet in length and can hold 6 people on board. These boats have to be built strong so that they can withstand the pull of the bigger fish and also the thrust of the ocean water.
A head boat or party boat is also used for fishing expeditions. These boats are built larger and can hold many more people. The party boat offers a lot more of comfort and luxury so that your guests can fish enjoy the water and also relax. Party boats are used for family get together and picnics.
3. Selecting an apt fishing boat The novice fisherman or the experienced one can both find a fishing boat that is suitable for their needs and that can be handled by them easily. In case you are not sure as to what kind of boat you should buy, you should read up about the different kinds of fishing boats and see what suits your requirement the best.
