Earlier models require 90 wt. and newer models 140wt. More important however is to use only API GL1 rated oil, regardless of weight. GL1 contains no sulphur-based high pressure additives. These additives will cause severe corrosion of the Seagulls bronze/brass lower end bearings/bushings. GL1 is still used in old car transmissions and is common in the food processing and timber/lumber industries.
trying to find service manual for a british seagull outboard 2 hp. motor?
The impeller is located inside the water pump housing, on the topside of the gearcase. The gearcase will have to be removed in order to service it.
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.
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 pump impeller on a 7.5 hp Mercury outboard, is located on top of the gearcase, and is driven by the driveshaft.
Motors that are mounted on the outside of a boat. The engine, gearcase, and propeller are mounted in a single case attached to the outside of the hull. Outboard motors range in size from 3 to 300 horsepower.An inboard motor is mounted inside the hull, with a propeller shaft protruding through the hull.
The gearcase assembly on an outboard engine is sealed, and draining is not needed. If however, the gear lube has not been changed in a while, during the water pump replacement is generally a good time to do so.
I would assume there is no oil reservoir in that motor. The oil is mixed in with the gas each time you fill the tank. There is probably lubricant (oil) in the lower unit gearcase, but I don't know the procedure for changing that.
By measuring the exhaust housing, between the powerhead, and where the gearcase bolts on. A shortshaft engine will have an exhaust housing length of approximately 15 in. The longshaft engine will measure 20 in.
Yes. For example, you can have an outboard motor on a boat.
