Alignment tool MerCruiser Alpha and Bravo

Genuine MerCruiser alignment tool for aligning the engine and drivetrain. The tool is used to check and adjust engine alignment and when replacing the thrust bearing. Proper alignment is essential to ensure long life of the drivetrain, driveshaft and bearings.

The tool should slide easily into the shield, support bearing and engine flywheel coupling. The inner ring of the support bearing can be adjusted slightly with a feeler gauge. If the tool still does not slide easily into place, the engine mounting feet should be adjusted. Lightly greasing the tool will help you see where the alignment is and how to adjust the engine.

When removing the drive, it may be necessary to adjust the engine, especially if the drive is difficult to remove. The engine feet may sag over time, so raising them may make removal easier.

A well-aligned engine prevents damage to the drive shaft and protects the support bearing.

Thermostat kit to fit GM based MerCruiser engines from 1987 onwards . The thermostat is designed for use in cooling systems with constant circulation and has an opening temperature of 160°F (71°C) . The kit includes all necessary gaskets for thermostat replacement.

The thermostat is an important part of the engine's cooling system. It regulates the engine's operating temperature . A faulty thermostat can cause the engine to overcool or overheat . In the worst case, the engine can boil, but running too cold is also not good, as it increases wear and fuel consumption .

Make sure the thermostat opens and closes at the correct temperature. You can test your current thermostat by heating it in water and checking to see if it opens at the correct temperature. If you are unsure about the thermostat's operation, it is a good idea to replace it .

A worn or damaged thrust bearing often causes noise and can lead to more serious damage if not replaced in a timely manner.

The bearing is supplied with a grease nipple plug, as this model has permanent grease. An alignment tool is recommended for installation to ensure the new thrust bearing is correctly aligned.

Thermostat kit Mercruiser V6 & V8

Thermostat kit to fit GM based MerCruiser V6 and V8 engines from 1983 onwards . The thermostat is designed for use in cooling systems with constant circulation and has an opening temperature of 140°F (60°C) . The kit includes all necessary gaskets for replacement.

The thermostat is an important part of the engine cooling system, as it regulates the engine's operating temperature . A faulty thermostat can cause overcooling or undercooling . In the worst case, the engine can boil, but running too cold is also not good, as it increases wear and fuel consumption .

Make sure the thermostat opens and closes at the correct temperature. You can test your current thermostat by heating it in water and checking to see if it opens at the correct temperature. If you are unsure about the thermostat's operation, it is a good idea to replace it .

Note: Not suitable for HI-Performance engines.

Trim tab Mercury / MerCruiser 35 HP+

Genuine Mercury aluminum anode and trim fin. The trim fin fits most Mercury and Mariner engines 35 horsepower and up *. It also fits all MerCruiser drives (except Bravo drives) .

The trim plate corrects the propeller torque and also acts as a sacrificial anode . Replace the sacrificial anodes in time to maintain corrosion protection. Sacrificial anodes are made of a baser metal than the drive unit, which is why they corrode first, thus protecting the boat from the harmful effects of water. A general rule of thumb is to replace the anode when about half of the material has worn away due to corrosion. However, the trim plate also has a steering function, so it should always be intact .

* Mercury 40–60 EFI: This trim plate only fits engines with a large gear case ( 2.31:1 ratio). Alternative trim plate: 82115 .

Universal relay Mercury and MerCruiser

Universal relay for Mercury and MerCruiser engines. The relay can be used as both a starter and trim pump relay, and is also called a solenoid. The relay was originally used in older MerCruiser trim pumps from 1974-1976, but is now widely used as a universal relay in both Mercury MerCruiser engines and many other sterndrive and inboard engines.

If the starter motor or trim pump is not working properly, this relay could be a possible cause of the problem.

Compatibility

• Mercury and MerCruiser sterndrives and inboard engines

• Suitable as starter and trim pump relay

• Universal solution for multiple engines

Product information

• Product type relay solenoid

• Application starter and trim pump

• Distance between mounting holes approx. 55 mm

• Width approximately 7 mm

• Original equivalent spare part

Additional information

• OEM number 25661T1

• Previous OEM numbers 256611 and 25661

In the event of electrical system malfunctions, it is worth checking the condition of the relay, as a faulty relay can prevent starting or the trim system from functioning.

Seawater hose kit for MerCruiser Bravo drives

Seawater hose kit for MerCruiser Bravo drives. A genuine MerCruiser replacement part designed to ensure reliable and leak-tight operation of the cooling system.

The hose kit fits earlier models of Bravo I, II and III towbars. Some later model years may have an alternative hose solution, so if you are unsure of the OEM number, it is recommended to compare the part to the product image. The towbar serial number alone is not always sufficient to identify the correct hose.

The condition of seawater hoses should always be checked during maintenance, as a damaged or worn hose can cause water to enter the drive unit or engine compartment.

Compatibility

Fits the following MerCruiser drives

• Bravo I

• Bravo II

• Bravo III

Especially early models. Newer models may have a different hose design.

Product information

• Product type seawater hose kit

• Application: seawater suction

• Genuine MerCruiser spare part

Additional information

• OEM number 8M0090859

Regular inspection of seawater hoses and replacement if necessary prevents water damage and ensures proper operation of the cooling system.
