You just don't want to try to draw water up into the pump. It'll be running dry while you're trying to prime it. more
I started in to it yesterday afternoon and here is what I found. [links]
Being unfamiliar with inboards, I just start following the water lines. The lake water pickup is on the port side of center, right next to the transmission through the bottom of the boat near where the drive shaft enters the hull. That hose runs to the starboard front side of the motor to the pump. The pump then outlets down the starboard side of the motor through a heat exchanger to cool the transmission fluid, a hose exits the transmission cooler turns down under the transmission and runs across to the port side, comes up and enters an engine oil cooler. A hose then exits the engine oil cooler going forward up to the engine water circulation pump. [links]
The last step in every oil change is pouring in the fresh oil. Your engine manual will give you the viscosity and API rating for the oil recommended by the manufacturer. Screw-top containers make it simple to pour the oil into the filler opening on top of the engine, provided there is ample room to turn up the container. If not, you can avoid a lot of irritation by using a funnel and a piece of hose to get the oil from the container to the engine. Rig a wire hook to the end of the hose to hold it inside the filler opening.
Engine manufacturers typically recommend an oil change every 100 hours, and at least once a year. Even if your engine manual allows for a longer interval between oil changes, changing the oil more often will extend the life of the engine.
Before you begin an oil change, the engine should be hot. Warm oil is easier to suck through a rubber hose or brass straw, but the reason for running the engine is more essential than that. You are changing the oil because it is contaminated with abrasive and chemical impurities. But the dirt in oil is just like dirt in water; leave it undisturbed and it settles to the bottom. Suck out the cold oil and much of the dirt stays behind, immediately contaminating the fresh oil and defeating the whole purpose of the oil change. Run the engine to get all of the contaminants in suspension so they come out with the oil. here
The trick to hassle-free oil changing is to find a method that works for your engine installation. Here are some possibilities.
One hundred engine hours between oil changes is fine for gasoline engines, but diesel engines are much harder on their lubrication. You should change the oil in a diesel engine about every 50 hours. The shorter interval is especially important for sailors who use their engines for only an hour or two per outing. Dirty oil sitting idle becomes destructive to the internal surfaces of the engine. If your boat will be idle for a while — over the winter, for example — it is imperative to remove the contaminated oil and fill the engine with clean oil.
Some older engines are equipped with cartridge type oil filters. A center bolt typically holds the filter housing in place. Release the bolt and remove the canister. Empty it and discard the old cartridge. Clean the housing with diesel fuel (or kerosene) and insert the new cartridge. If a separate sealing ring is included with the cartridge, carefully pry the old seal out of its seat by pricking it with a straight pin. Coat the new seal with oil and push it into position. Reinstall the canister.
