How to Identify Your 28HP Model

Nameplate location: Look for the model/serial plate on the transom bracket or swivel bracket. It lists the model code and serial number.
Reading the model code: The base code identifies horsepower; suffix letters typically indicate shaft length (S/L/XL), control type (tiller vs. remote), and production year/series.
2‑Stroke specifics: Most 28HP units are carbureted 2‑cylinders. Some use premix; others may have oil injection. Confirm which system your engine uses before servicing.
Starting and controls: Note whether your engine is rope or electric start and whether it has tiller or remote controls—these details help match ignition switches, harnesses, and cables.

Engine Overview

28HP Inline‑2 Carbureted 2‑Stroke

Feature	Description
Configuration	Inline‑2, carbureted 2‑stroke with mechanical fuel system and conventional magneto/CD ignition.
Common Models	28HP variants in short/long shaft, rope or electric start, tiller or remote configurations (year‑specific differences apply).
Advantages	Lightweight, simple to service, strong low‑to‑mid‑range torque for small craft.
Notes	Many parts cross with 25/30HP siblings of similar years; confirm by model code and serial number for exact compatibility.

Routine Maintenance & Service Parts

Intervals below are general guidelines for typical use. Always follow the procedures and schedules in your official service manual for your exact model and year.

Item	Interval*	Remarks	Parts Link
Gear oil (lower unit)	Every 100 hours or annually	Change sooner after water intrusion or submersion; inspect magnet for metal debris.	Johnson/Evinrude/OMC Service & Maintenance Kits
Spark plugs	Inspect every 50 hours; replace annually	Use the correct heat range and gap; replace if fouled, worn, or cracked.	Spark Plugs
Fuel filter / inline strainer	Every 100 hours or annually	Replace more often if using ethanol‑blended fuel or after contamination events.	Fuel Filters
Water pump impeller / pump kit	Every 2–3 seasons (or sooner in sandy/silty water)	Weak tell‑tale or overheat alarms often trace to a worn impeller or housing wear.	Johnson/Evinrude/OMC Water Pump Repair Kits
Anodes (corrosion protection)	Inspect every 3–6 months; replace when ~50% depleted	Choose zinc for saltwater, aluminum for brackish, magnesium for fresh water where applicable.	Johnson/Evinrude/OMC Anodes
2‑Stroke oil usage	Every fill‑up (if premix)	Premix TC‑W3 marine oil at 50:1 unless your engine is equipped with and calibrated for oil injection.	Johnson/Evinrude/OMC Outboard Parts
Oil injection (VRO) system check — if equipped	Annually	Inspect hoses, clamps, and pump diaphragm; verify alarms and prime procedure.	Fuel Pumps
Gearcase seals inspection	Annually or if milky gear oil is found	Pressure/vacuum test after seal replacement; replace any nicked seal or worn shift shaft bushing.	Johnson/Evinrude/OMC Lower Unit Seal Kits

*Intervals vary by environment and duty cycle. Follow the schedule for your exact model/year.

Common Symptoms & Quick Checks

Symptom	Check First	Related Parts
Weak tell‑tale or overheat alarm	Inspect intake screen for debris; check impeller condition and thermostat operation.	Water pump kit, impeller, thermostat, intake screen
Poor acceleration / power loss	Check for fouled plugs, restricted fuel filter, clogged carb jets, damaged prop, or timing/ignition issues.	Spark plugs, fuel filter, carburetor kit, propeller, ignition coil/power pack
Hard starting / rough idle	Verify primer bulb and fuel line integrity; confirm choke/enricher function and correct plug gap.	Spark plugs, carburetor kit, fuel pump diaphragm, fuel lines
Excessive smoke (2‑stroke)	Confirm correct oil ratio; check for stuck choke, leaking needle/seat, or cold‑running thermostat.	Spark plugs, thermostat, carburetor needles/seats, fuel/oil pump
Gearcase noise / metal in oil	Inspect drain plug magnet; pressure/vacuum test for leaking seals; verify gear lash.	Gear lube, lower unit seal kit, bearings

FAQs

Are 28HP parts interchangeable with other Johnson/Evinrude models?

Some maintenance items (plugs, filters, anodes) and many hardware pieces cross with 25/30HP engines from similar eras. Gearcase, ignition, and carburetion can vary by year and configuration. Always confirm using the model code and serial number.

When should I replace the impeller?

As a preventative measure, replace the impeller every 2–3 seasons, or sooner if you operate in sandy/silty water or notice a weak tell‑tale. If the pump housing is scored, use a complete water pump repair kit.

How often should I change lower unit gear oil?

Change gear oil every 100 hours or annually, and anytime you see milky oil (water intrusion) or after an impact or submersion event.

What information do I need to confirm part compatibility?

Provide the model code, serial number, shaft length (S/L/XL), start type (rope/electric), and control type (tiller/remote). Photos of the nameplate and the part needing replacement are very helpful.
