How to Identify Your Parsun 2‑Stroke Model

Locate the nameplate/serial label on the clamp bracket or swivel bracket. Record the model code, serial number, and shaft length (S, L, or XL).
Read the model suffix: it often indicates tiller vs. remote control, manual vs. electric start, and shaft length.
Confirm it’s a 2‑Stroke: premix fuel/oil or an oil‑injection tank and lines, and carbureted intake are typical markers.
For mid‑range motors, note whether you have a twin‑cylinder or triple‑cylinder platform; this affects impeller size, propeller dimensions, and ignition parts.

Platform Overview

Portable Class (approx. 2–9.8 HP)

Feature	Description
Configuration	Single or twin‑cylinder, carbureted 2‑Stroke, manual or electric start.
Common Models	Examples include T2BMS, TC3.6BM, T3.6BM, T5.8BM, T9.8BM.
Advantages	Lightweight, simple maintenance, strong low‑speed thrust for small boats.
Notes	Confirm shaft length and propeller pitch; impeller and spark plug specs vary by model code.

Mid‑Range Class (approx. 15–90 HP)

Feature	Description
Configuration	Twin or triple‑cylinder, carbureted 2‑Stroke; remote or tiller control options.
Common Models	Examples include T15BM, T25/T30BM, T40BM, T75/T90BM.
Advantages	Strong acceleration, straightforward service, wide propeller selection.
Notes	Carburetor jetting, ignition components, and water pump kits are model‑specific; verify your exact model code and year.

Routine Maintenance & Service Parts

Intervals below are general guidelines; always follow your official service manual for your specific model and operating conditions.

Item	Interval*	Remarks	Parts Link
Gear oil (lower unit)	Every 100 hrs or annually	Inspect for water intrusion (milky oil) and metal on the drain plug magnet.	Lower Unit Seal Kits
Spark plugs	Inspect every 50 hrs; replace 100–200 hrs	Use the heat range and gap specified for your model; replace if fouled or worn.	Spark Plugs
Fuel filter / inline filter	Every 100 hrs or annually	Replace sooner if contaminated fuel is suspected; check for restricted flow.	Fuel Filters
Water pump impeller / kit	Every 2 seasons or 200 hrs	Replace sooner if weak tell‑tale or overheat alarm occurs; avoid dry starts.	Water Pump Impeller Kits
Anodes (corrosion protection)	Inspect every 50 hrs; replace when 50% consumed	Match anode material to your water type (fresh/brackish/salt).	Anodes
2‑Stroke fuel/oil mix or oil‑injection service	Every 100 hrs or annually	Verify mix ratio (commonly 50:1 TC‑W3) or inspect oil tank, lines, and pump for injection systems.	Hoses
Propeller inspection	Every 50–100 hrs	Check for dings, bent blades, and fishing line around the prop shaft; grease splines.	Propellers

Common Symptoms & Quick Checks

Symptom	Check First	Related Parts
Weak tell‑tale stream or overheat alarm	Inspect intake screens, impeller condition, and thermostat operation.	Water pump impeller kit, thermostat, intake screen.
Poor acceleration or power loss	Check propeller damage/slip, fuel filter restriction, and carburetor jets for debris.	Propeller, fuel filter, carburetor repair parts.
Hard starting or rough idle	Verify choke/enrichment function, spark plug condition/gap, and fuel quality.	Spark plugs, carburetor kit, fuel pump.
Excessive smoke (2‑Stroke)	Confirm correct fuel/oil mix ratio; check for stuck choke or flooded carburetor.	Spark plugs, carburetor parts, fuel components.
Gearcase noise or metal in gear oil	Drain and inspect gear oil; check prop shaft seals and water intrusion.	Lower unit seal kit, bearings, thrust washers.

FAQs

Are parts interchangeable between different years or platforms?

Some items cross over, but many 2‑Stroke components—such as carburetor jets, ignition parts, and water pump kits—are model‑specific. Always match your exact model code, serial, and shaft length before ordering.

When should the impeller be replaced?

A practical guideline is every two seasons or about 200 hours. Replace immediately if the tell‑tale weakens, the motor overheats, or the pump has been run dry.

How often should gear oil be changed?

Typically every 100 hours or at least once per season. Inspect the drain plug magnet and oil color; milky oil indicates water intrusion and the need to service seals.

What information do you need to confirm part compatibility?

Please provide the model code, serial number, shaft length, control type (tiller/remote), approximate year, and clear photos of the nameplate and the part you’re replacing.
