- Power trim adjusts running angle
- EFI fuel delivery system
Description
Deploy the Mercury 20EPT to fix poor holeshot on low-profile skiffs. The EFI computer regulates fuel delivery into the 15-inch shaft powerhead. You feel sharp throttle translation navigating loaded fiberglass hulls through twisting inland creeks. Measuring your low transom confirms this 15 inch shaft mercury outboard motor operates without sucking air.
Fighting heavy bow rise under hard acceleration? The factory power trim serves as a structural solution. The operator tucks the engine in from the helm to push the bow down fast. Mercury reinforces the gearcase with impact-deflecting aluminum geometries. This thick-wall casting survives hidden submerged log strikes. Precision throttle linkage alignment is crucial when repowering skiffs with remote power.
Key Features of Mercury 20EPT
- Electronic fuel injection vaporizes gas instantly into the cylinders regardless of temperature, ensuring crisp throttle translation on lightweight fiberglass hulls.
- The 15-inch short shaft matches standard low transoms exactly, preventing excessive drag from a deep gearcase and increasing top speed.
- Power trim hydraulics lift the skeg completely clear of mud flats at the push of a button, preventing catastrophic propeller strikes.
- Forward remote control integration connects your steering wheel directly to the engine pivot tube, sharpening handling response in narrow creeks.
- A reliable 12-amp charging system keeps your cranking battery topped off automatically, powering demanding fish finders and livewell pumps reliably.
- Impact-deflecting aluminum geometries reinforce the lower unit housing tightly, protecting internal gears against hidden submerged log strikes in shallow water.
- Routing exhaust gases through the propeller hub eliminates surface fumes completely, ensuring clean air for the operator at the rear console.
- A conveniently located engine oil drain plug simplifies routine lubrication changes, saving significant time during seasonal maintenance prep.
- Vibration-isolating rubber engine mounts absorb powerhead shaking effectively, delivering a much smoother ride across rough chop and boat wakes.
- EPA-approved clean idle technology burns fuel without leaving an oil slick, allowing legal operation on highly restricted inland lakes and reservoirs.
Why Choose Mercury 20EPT
This exact model demands a 15-inch transom height paired with a complete forward helm station. Attaching it to a 20-inch transom leaves the cooling intakes completely dry. Tiller conversion is physically impossible without factory retrofits. Finding a low transom remote outboard fits specific classic hulls.
- Confirm your transom measures exactly 15 inches vertically down the centerline.
- Route mechanical steering and shift cables cleanly avoiding sharp pinch points.
- Operate legally on restricted waters using EPA-approved clean idle technology.
Warranty, Support and Maintenance
Pleasure applications carry a 3-Year Limited Warranty and a 3-Year Corrosion Warranty. Registered commercial fleets utilize a 1-Year Limited Warranty containing no corrosion protection. Routine service involves draining gear lube and replacing spark plugs as defined by the factory manual. Document all fluid changes. Parts counters demand your specific engine serial number to verify hardware compatibility. For product details and order support, Mulmotor offers assistance before your purchase is placed.
