A motorboat is a boat in which an outboard motor An outboard motor is a propulsion system for boats, consisting of a self-contained unit that includes engine, gearbox and propeller or jet drive, designed to be affixed to the outside of the transom and are the most common motorized method of propelling small watercraft. As well as providing propulsion, outboards provide steering control, as they is installed on the rear and contains the internal combustion engine The internal combustion engine is an engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber. In an internal combustion engine the expansion of the high temperature and pressure gases, which are produced by the combustion, directly applies force to a movable component of the engine, such as the, the gearbox Using the principle of mechanical advantage, a transmission or gearbox provides a speed-torque conversion from a higher speed motor to a slower but more forceful output or vice-versa, and the propeller A propeller is a type of fan which transmits power by converting rotational motion into thrust. A pressure difference is produced between the forward and rear surfaces of the airfoil-shaped blade, and air or water is accelerated behind the blade. Propeller dynamics can be modeled by both Bernoulli's principle and Newton's third law.
An inboard/outboard contains a hybrid of a powerplant and an outboard, where the internal combustion engine is installed inside the boat, and the gearbox and propeller are outside.
There are two configurations of an inboard, v-drive and direct drive. A direct drive has the powerplant mounted near the middle of the boat with the propeller shaft straight out the back, where a v-drive has the powerplant mounted in the back of the boat facing backwards having the shaft go towards the front of the boat then making a 'V' towards the rear. The v-drive has become increasingly popular due to the wakeboarding Wakeboarding is a surface water sport which involves riding a wakeboard over the surface of a body of water behind a boat. It was developed from a combination of water skiing, snow boarding and surfing techniques and wakesurfing Wakesurfing is a water sport in which a surfer trails behind an inboard ski boat, surfing the boat's wake without being directly attached to the boat. The wake from the boat mimics the look and feel of an actual ocean wave. After getting up on the wave by use of a tow rope, wakesurfers drop the rope and ride the steep face below the wave's peak in sports.
Motorboats vary greatly in size and configuration, from the 4-meter, open Boston Whaler Boston Whaler, or just "Whaler," is a brand of motorboat manufactured in the United States. Classically, a Whaler is characterized by a foam-cored fiberglass hull , with an outboard motor and center steering console. They are manufactured by Boston Whaler, Inc type to the luxury mega-yachts A yacht is a high end recreational boat. It designates two rather different classes of watercraft, sailing and power boats. Yachts are different from working ships mainly by their leisure purpose. It was not until the rise of the steamboat and other types of powerboat that sailing vessels in general came to be perceived as luxury items. However, capable of crossing an ocean.
History
Although the Screw propeller A propeller is a type of fan which transmits power by converting rotational motion into thrust. A pressure difference is produced between the forward and rear surfaces of the airfoil-shaped blade, and air or water is accelerated behind the blade. Propeller dynamics can be modeled by both Bernoulli's principle and Newton's third law had been added to an engine (steam engine A steam engine is a heat engine that performs mechanical work using steam as its working fluid) as early as the 18th century in Birmingham Birmingham (pronounced /ˈbɝːmɪŋəm/ , BUR-ming-əm, locally /ˈbɝːmɪŋɡəm/ BUR-ming-gəm) is a city and metropolitan borough in the West Midlands county of England. Birmingham is the largest of the British Core Cities and the second most populous British city, with a population of 1,006,500 (2006 estimate), England England ( /ˈɪŋɡlənd/ ) is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west; the Irish Sea is to the north west, the Celtic Sea to the south west and the North Sea to the east, with the English Channel to the south separating it from continental Europe. The mainland of by James Watt James Watt, FRS, FRSE was a Scottish inventor and mechanical engineer whose improvements to the Newcomen steam engine were fundamental to the changes brought by the Industrial Revolution in both the Kingdom of Great Britain and the world, the petrol engine A petrol engine is an internal combustion engine with spark-ignition, designed to run on petrol (gasoline) and similar volatile fuels only came about in the later part of the 19th century, at which point Frederick William Lanchester Frederick William Lanchester, Hon FRAeS was an English polymath and engineer who made important contributions to automotive engineering, aerodynamics and co-invented the field of operations research recognized the potential of combining the two components to create the first all British powerboat, tested in Oxford Oxford (pronounced /ˈɒksfɚd/ ) is a city, and the county town of Oxfordshire, in South East England. The city has a population of just under 165,000, with 151,000 living within the district boundary. The rivers Cherwell and Thames run through Oxford and meet south of the city centre. For a distance of some 10 miles (16 km) along the river, in England the powerboat was born. Late in that same period fishermen in San Francisco San Francisco is the fourth most populous city in California and the 12th most populous city in the United States, with a 2008 estimated population of 808,976. The only consolidated city-county in California, it encompasses a land area of 46.7 square miles on the northern end of the San Francisco Peninsula, making it the second most densely were being transforming their feluccas A felucca is a traditional wooden sailing boat used in protected waters of the Red Sea and eastern Mediterranean including Malta, and particularly along the Nile in Egypt. Its rig consists of one or two lateen sails into early versions of the Monterey clipper, also known locally as put-puts.
Lanchester began to find the conflict between his job as works manager and his research work irksome. Therefore, in 1893, he resigned his position in favour of his younger brother George. At about the same time, he produced a second engine similar in design to his previous one but running on benzene 800 r.p.m. An important part of his new engine was the revolutionary carburettor A carburetor or carburettor (Commonwealth spelling), is a device that blends air and fuel for an internal combustion engine. It was invented by Karl Benz before 1885 and patented in 1886. It is colloquially called a carb (in North America and the United Kingdom) or carby (chiefly in Australia).[citations needed], for mixing the fuel and air correctly. His invention was known as a wick carburettor, because fuel was drawn into a series of wicks, from where it was vapourized. He patented this invention in 1905.
Lanchester installed his new petrol engine in a flat-bottomed launch, which the engine drove via a stern paddle wheel. Lanchester built the launch in the garden of his home in Olton Olton is an area of the Metropolitan Borough of Solihull in England. It is located on the A41 between Solihull town centre and Acocks Green, and dates back more than 1,000 years, Warwickshire Warwickshire (pronounced /ˈwɒrɪkʃər/ or /ˈwɒrɪkʃɪər/) is a landlocked non-metropolitan county in the West Midlands region of England. The county town is Warwick, although the largest town is Nuneaton in the far north of the county. The shape of the administrative area Warwickshire differs considerably from that of the historic county. The boat was launched at Salter’s slipway in Oxford Oxford (pronounced /ˈɒksfɚd/ ) is a city, and the county town of Oxfordshire, in South East England. The city has a population of just under 165,000, with 151,000 living within the district boundary. The rivers Cherwell and Thames run through Oxford and meet south of the city centre. For a distance of some 10 miles (16 km) along the river, in in 1904, and was the first motorboat built in Britain.

A. Oil should be a honey color, just like in your car. However cream color indicates a major problem. This is true of car and boat engines. Whether it's a blown head gasket or a cracked block, from freezing, or rust through. This engine is 33 years old, so I would be careful about undertaking major overhaul. It's replacement time.
