How to Identify Your 75–85HP Model

Nameplate location: look for the identification/serial plate on the transom bracket (starboard side) or swivel bracket. Record model code and serial number.
Model code basics: suffix letters typically indicate shaft length (e.g., S/L/XL), manual vs. electric start, and tiller vs. remote steering. The year can be encoded by a letter/number—check your service manual.
Platform clues: these 2‑Stroke engines are commonly inline‑3 carbureted designs. Visual hints include a 3‑carb layout and an external oil tank if equipped with oil injection.
2‑Stroke distinction: premix models require a fuel/oil mixture; oil‑injected models include an oil tank, pump, and delivery lines that should be inspected periodically.

Routine Maintenance & Service Parts

Intervals below are general guidelines for typical recreational use. Always follow the official service manual for your exact model and operating conditions.

Item	Interval*	Remarks	Parts Link
Gear oil (lower unit)	Every 100 hours or annually	Inspect for water intrusion/metal; replace drain/vent gaskets; service seals if contamination is found.	Yamaha Lower Unit Seal Kits
Spark plugs	Inspect every 50 hours; replace 100–200 hours (as needed)	Check gap and color; replace if fouled or worn.	Spark Plug
Fuel filter / water separator	Every 100 hours or annually	Drain/replace and monitor for water or debris; renew fuel hoses if hardened.	Fuel Filters
Water pump impeller / kit	Every 2 seasons or 200 hours (inspect annually)	Essential for cooling; replace sooner if weak tell‑tale or overheat symptoms appear.	Yamaha Water Pump Repair Kits
Anodes	Inspect every 50 hours; replace when 50% consumed	Match anode material to water type (salt, brackish, fresh) for best protection.	Yamaha Anodes
Premix ratio / oil injection system	Each fuel fill‑up; inspect seasonally	Use the factory‑specified premix ratio if applicable; for oil injection, inspect pump cable setting, filters, and oil lines for leaks.	Hoses
Propeller inspection	Every 50 hours and after impacts	Check blades and hub for damage; remove prop to clear line and grease shaft.	Yamaha Propellers

Common Symptoms & Quick Checks

Symptom	Check First	Related Parts
Weak tell‑tale or overheat alarm	Inspect intake screen for blockage; verify tell‑tale hose is clear; check impeller and thermostat.	Water pump kit, thermostat, intake screen
Poor acceleration / power loss	Check prop for damage or hub slip; replace fuel filter; verify fresh plugs; confirm throttle opens fully.	Propeller, fuel filter, spark plugs
Hard starting / rough idle	Prime fuel system; verify choke/enrichment operation; inspect/clean carbs; check for air leaks in fuel lines.	Carburetor service parts, fuel hoses, spark plugs
Excessive smoke (2‑Stroke)	Confirm correct fuel/oil ratio; check stuck choke; verify thermostat isn’t stuck open (engine not warming up).	Spark plugs, carburetor service parts, thermostat
Gearcase noise or metal in gear oil	Drain and inspect oil; look for water (milky oil); pressure/vacuum test and service seals; inspect bearings/gears.	Lower unit seal kit, bearings, gear oil

FAQs

Are parts interchangeable between different years or platforms?

Many routine items (impellers, plugs, anodes, filters) remain consistent across the Selva 75–85HP 2‑Stroke family, especially where the design mirrors Yamaha 75/85 platforms. Always confirm via model/serial plate and physical comparison before ordering.

When should the impeller be replaced?

Inspect annually and replace every 2 seasons or ~200 hours, sooner if cooling flow weakens or the engine has seen sand/silt. The impeller is a critical wear item in all outboards.

How often should I change the gear oil?

Typically every 100 hours or at least once per season. If you discover milky oil (water intrusion) or metal debris, perform a seal service and re‑test before further use.

What information do you need to confirm part compatibility?

Please provide the exact model code, serial number, shaft length, control type (tiller/remote), and clear photos of the nameplate and the part area. This allows us to validate cross‑references where applicable.
