With a helper holding the engine steady, remove the wedge supports, lower the engine and reconnect the mountings loosely.
- Perhaps most importantly, high-quality marine spark plug wires contribute to improved fuel efficiency. By ensuring that the spark plugs receive a consistent and powerful spark, these wires help to maximize the combustion process, resulting in more efficient engine operation and reduced fuel consumption. This not only saves money on fuel costs but also helps to reduce emissions and promote a cleaner environment.
2) Housing design
- Oil tank gaskets are typically made of rubber or other flexible materials that can withstand the high temperatures and pressures that are present in an oil tank. They are designed to create a tight seal between the tank and its components, such as the lid or access port, to prevent oil from escaping and causing a mess or posing a safety hazard.

In recent research, MWCNTs and carbon black were mixed with the butadiene/natural rubber to form a hybrid composite which gives very strong filler links by partial replacement of carbon black based on the m1:m2:X (m1—MWCNT; m2—reduction amount of carbon black; X-varies from 1 to 6) [40,64]. An internal blending mixer and two-roll milling were used to formulate the composites. The synergistic effect plays a major role in improving the abrasion resistance property due to the partial replacement of carbon black by adding MWCNTs in different ratios. The optimal ratio value of MWCNTs is 5 (parts per hundred of rubber) and 27.5 (parts per hundred of rubber) for carbon black with better resistant to abrasion compared to the matrix material [64]. The vulcanized hybrid composite material reinforced with MWCNT/carbon black at the ratio of 1:1 shows better mechanical properties, curing characteristics, and thermal conductivity. This shows a better tyre thread with an improved endurance life, less curing time, and improved thermal conductivity [42,64]. Fig. 4.4 shows the SEM and TEM images of uncured and cured rubber and Figs. 4.5 and 4.6 show the application of rubber nanocomposites in a tyre application.
4. SHAFT SPEED: As different shafts move at different speeds you need to consider the runout, the housing bore, and oil type being sealed. Ensure you select a seal that will not suffer from abrasions or spiralling.
