Standing behind your boat, the indicator stream will be on your right of the motor not far below the cowling. This is not the total amount of water coolant involved, it's put there to give you a visual confirmation that your engine is being cooled. The main intake/outlet are down on the lower shaft. If you don't see a nice healthy indicator stream coming from your right side of the motor, then your water pump needs replacing or you have a blockage that needs to be addressed. I grew up running one of those 70s with a jet unit on it, that was the most reliable outboard I've ever run.
The operating water pressure for a 1995 Evinrude 130hp outboard motor typically ranges from 4 to 7 psi. This pressure ensures that the cooling system is functioning properly, allowing for efficient engine cooling. If the pressure falls outside this range, it may indicate a blockage or issue with the water pump or cooling system. Regular maintenance and checks are recommended to ensure optimal performance.
If you will go to Crowley Marine you can look up just about any old outboard motor. There is a diagram there for the 1971 25 hp Evinrude and if you will look there is a plate on the right side looking at the motor from the propeller end just below where the gearcase extension bolts on. It has several small holes in it and this is the water intake. On the Crowley gearcase drawing it is part #19.
The water inlet for a 1990 Evinrude outboard motor is typically located on the lower unit, near the propeller. It is often a small, screened opening that allows water to enter the cooling system. Make sure to regularly check and clean this inlet to prevent debris from obstructing water flow, which could lead to overheating. If you're having trouble locating it, consult the motor's service manual for specific diagrams and details.
Putting a water hose in the motor is not recommended as it can cause damage to the engine. Water entering the motor can lead to hydro-lock, which can result in severe engine damage. It is essential to keep water away from the motor and use appropriate cleaning methods.
A 13-foot inflatable boat powered by a 25 hp Evinrude motor can typically reach speeds of around 20 to 30 knots, depending on factors such as weight, load, and water conditions. Generally, with optimal conditions and a light load, you might expect closer to the higher end of that range. However, performance can vary, so it's best to check with specific boat and engine performance data for more precise estimates.
If the use of a professional to replace the water pump is out of the question, then one should use the manual to locate the correct part on their particular model of the motor. Once it is found, follow the instructions listed in the manual for replacing the part.
On the side of the engine block on bottom of the motor
Yes it should come out from starboard side, its perfectly normal, if it doesn't than you have a problem.
It could be a freeze plug on the side of the engine block by the motor mount.
Very carefully
The water pump for an s-10 engine is located on the front of the motor. The engine can be damages if it overheats due to a bad pump.
The 2003 model, 200hp Evinrude outboard, may be equipped with either a standard gearcase, which has the common inlets on both port and starboard sides of the case, or with a high performance Lightening gearcase utilizing a low water pick-up. The linlet on the later design is located underneath the nose of the gearcase bullet.
