These I think you will find were made in Yugoslavia by the Tomos company and sold under the "sea Bee " brand in the UK for some reason.
I may be stating the obvious here but usually outboard gearboxes have 2 plugs one top and one bottom. Take out both to drain the oil and then fill from the bottom hole forcing in the oil till it comes out of the top hole, then refit the top plug followed byt the bottom one.

Coleman outboard overheating

You should change your impeller.
It is located at the top of the gearbox, around the vertical engine shaft.
First, disconnect the gear control. Underneath the steering bracket, you'll see a long nut with a counternut. ( Maybe you'll have to shift FWD or BWD to get better access ). Loosen the counternut 1/4 turn and then turn the long nut up ( 2 open box wrenches 10mm ).
Then remove the 4 bolts holding from lower to upper the gearcase ( just above the anti-cavitation plate )
The gearbox should drop down easily.
Then remove the 4 screws of the waterpump ( top of gearcase, around the long vertical shaft ). Lift the waterpupp housing, you'll get the impeller.
To reassemble the waterpump, grease the cup in the housing with PTFE or silicone grease, and while pushing the housing down over the impeller, rotate the shaft clockwise.
Reassemble all the rest in reverse order.
Check and adjust the gear shifting...

How to Change the impeller on Suzuki 140 outboard motor

Suzukis are normally a mission to work on especially if it is a two stroke,so I suggest you get a workshop manual.all gearbox bolts must be undone,the gear linkage is under the bottom carb,this is the tricky part,you have to loosen a nut at bottom of gear arm where gearcable fits,then push in with screw driver,this releases gear change shaft.the biggest problem is trying to see what you are doing.good luck

Water pump

The water pump is a flexible impellor located in the top of the bottom section of the leg of the outboard. It is driven by the drive shaft to the prop that is spinning all the time the motor is running. You will find it behind or near the water inlet slots at the bottom of the leg

Johnson 235HP Outboard - oil leaking from bottom leg - dark black so picking it is the two stroke oil

most 2 stroke motors will not burn all the oil in the mix and that unburned oil coats the exhaust leg and leaks out the thru hub exhaust and parting line of the lower to the housing. so keep some windex handy and clean it up.

We bought the Clymer Honda outboard shop manual (B757) which covers Honda 2-130 HP from 1979 to 1999.
It was $20 and worth every penny.

Hope this is helpful.

What type of oil for a 90 horsepower 1998 engine for a boat?

The outboard leg/transom leg oil is most important, where the gears drive the propeller it will need a heavy oil like hypoid gear oil No. 90. If it is a four cycle motor which doesn't need to have oil mixed with the gas, the base of the motor will have an oil plug and dipstick, and most likely take a high performance oil which acts as a coolant as well as a lube oil, so keep it right on but not over the full mark to avoid deadly engine heat.
If it is a Two-cycle motor you will need a 2cycle oil to mix with the gas according to that engine's particular mix strength on the instructions. Some are automatic oilers - 2cycle injection so you just keep the 2cycle oil tank full. You need to find a sticker on the motor or brochure to get the right oil weight and weather it can take the new multi-weight synthetic oils or not. Also oil the cables and steering pivots and all joints after you take it out of salt water and do your routine flush-out for the leg coolant water system with a hose - the coolant pump in the leg is not rust proof at all, even for fresh water boating.
