How to Identify Your 15HP Model

Nameplate location: check the serial/model plate on the starboard side of the swivel bracket or inside the transom clamp area.
Reading the code: examples like T15BMS/T15BML indicate engine family (T15), revision (B), start/control (M = manual; E = electric; R = remote), and shaft length (S = 15" short; L = 20" long).
2‑Stroke specifics: premix fuel is common on this class; 2‑strokes do not have an engine oil dipstick or oil filter, unlike 4‑strokes.
Platform cues: twin‑cylinder carbureted models resemble Yamaha 9.9/15 two‑stroke architecture; verify by comparing carburetor layout and gearcase style.

Routine Maintenance & Service Parts

Intervals below are general guidelines for small 2‑stroke outboards; always follow your engine’s official service manual.

Item	Interval*	Remarks	Parts Link
Gear oil (lower unit)	Every 100 hrs or annually	Use marine 90W GL‑5; inspect for water (milky oil). Reseal if contamination is found.	Lower Unit Seal Kits
Spark plugs	Inspect 50 hrs; replace 100 hrs/season	Gap to spec; replace if fouled from rich mix or excessive idling.	Spark plug
Fuel filter (inline)	Every 100 hrs or annually	Replace more often with ethanol fuel or debris‑prone tanks.	Fuel Filters
Water pump impeller/kit	Every 2–3 seasons (or overheat/weak telltale)	Replace sooner in sandy/silty water; kit includes impeller and wear components.	Water Pump Impeller Rebuild Kits
Anodes (internal/external)	Inspect each haul‑out; replace <50% remaining	Match alloy to water type (zinc/salt, aluminum/brackish, magnesium/fresh).	Anodes
2‑Stroke fuel/oil mix	Every fill‑up	Use fresh gasoline and TC‑W3 outboard oil at the ratio specified by your manual (commonly 50:1 for this class).	Service & Maintenance Kits

FAQs

Are parts interchangeable between Parsun 15HP 2‑Stroke and Yamaha 9.9/15 two‑stroke models?

Many service parts (impellers, plugs, some gearcase and carb components) follow the Yamaha 9.9/15 two‑stroke pattern. Always verify by model code, shaft length, and serial number before ordering.

When should I replace the impeller?

Every 2–3 seasons in normal use, or immediately if the telltale weakens, you experience an overheat, or you run in sandy/silty water frequently.

How often should lower unit gear oil be changed?

At least annually or every 100 hours. Inspect drained oil for water (milky color) or metal. If contaminated, reseal the gearcase before continued operation.

What information helps confirm part compatibility?

Provide the full model code (e.g., T15BMS/T15BML), serial number, shaft length, start/control type, and clear photos of the nameplate and the part you’re replacing.
