Rebuilt marine transmissions are not generally hard to install. Taking some extra time to ensure everything is in good working order before starting them up will lengthen their life span and keep them running their best. Start by going through everything systematically before installing the part and follow the precautions for a successful install. Afterwards, you simply need to maintain the system so you can avoid breakdowns and stay out on the water.

Pre-Installation Checks

The first item to check is the damper plate located on the engine flywheel inside of the engine’s bell housing. Replace and clean anything that needs it. The parts you should inspect in particular include the spline coupling, springs, and center hub. Next is the cooler. Install a new fluid heat cooler, check over the oil cooler hoses, and clean or replace any that need it. You always ensure the cooler is of equal height or slightly lower than the rebuilt marine transmissions before moving forward with the installation.

Water is important to drive systems, and marine systems are no different. The water pump impeller should be examined carefully and a new one installed before attaching a heat alarm system. This is also the best time to ensure the prop shaft is tightened properly and that the rebuilt part and engine have an identical rotation.

Mounting In Rebuilt Marine Transmissions

Letting the rebuilt part bend and turn while on the damper plate hub is one of the most common ways these parts are damaged during installation. If the entire part is not held securely and steady throughout the process, you will definitely have to wait for another one. The best way to install everything is to line up the parts with the boat in the water and let everything sit for a full two days. This will let the hull go back into the correct shape after it has been hauled. When lining everything up for the install, the couplings and shaft should be within .003 of an inch to prevent breaking the oil seal on the output shaft or the bearing.

Before testing everything out, you need to lubricate the entire system properly and make certain that it is not leaking. Doing this step correctly takes time, but will save you time and money in the long run. First, fill up the fluid reservoir and idle the engine for ten seconds. Top the fluid back off and run another fifteen seconds in idle, five seconds in neutral, and fifteen seconds in reverse before putting it back into neutral and shutting it down. Top the reservoir off again and repeat this process until there is no change in the fluid level.

Hints And Tips For Use

Make the fluid in rebuilt marine transmissions part of your pre-trip check. If it has a different color, smells burnt, or if the overheat alarm sets off, change the fluid before heading out onto the water. Leaks and low fluid levels should be repaired as soon as possible to prevent running the boat dry. When it is time for an oil change, take a few extra minutes to change the transmission fluid level as well.

Many people fail to use neutral gear as often as they should. The boat should sit in neutral for a few moments before putting the system into gear. This allows the clutch pistons to let off completely. Watch the motor RPM when shifting as well. Shifting with too high of an RPM can quickly destroy a boat’s drive system, so ensure it is sitting in idle before putting it into gear.

Rebuilt marine transmissions are a great choice for getting your boat up and running. A little extra care during the installation process and use of your boat can go a long way. Your boat will run at its best and last longer keeping you in the water.

How often to change the clutch and transmission fluid?
I have a 2006.5 Kia Optima with the 5-speed manual transmission. I don't have an owner's manual. At what mileage intervals should I change the clutch fluid and transmission fluid? I've never owned a car with a manual transmission before.
