Save on boat parts & accessories!
Seiler Marine offers huge savings on boat parts for sterndrives and outboard motors, as well as other boating accessories. Our prices include shipping in the continental US, so the price you see is what you pay.
Outboard Motor Parts
Choose from outboard parts for Chrysler, Evinrude, Force, Johnson, Mariner, Mercury, Mercury Sport Jet, Nissan, OMC Seadrive, Tohatsu and Yamaha outboard motors.
Sterndrive Parts
Sterndrive parts and complete outdrives are available for Mercruiser (R-Style, Alpha I, Gen II, Bravo I/II/III) and OMC Sterndrives (Electric Shift, 400/800 Series and Cobra).
A limited selection of Volvo-Penta parts are also available. Please use the price quote form to check stock.
Boat Part Manufacturers
Boat parts from Seiler Marine meet or exceed OEM specs and are manufactured by the top names in the marine business.
We also offer a limited selection of OEM Quicksilver parts (Mariner, Mercury, Mercruiser and Force) for those that prefer them, at lower prices than one might expect to pay for OEM parts.
Here is a partial list of the manufacturers we deal with:
API Marine manufactures electrical parts like power trim motors, starters and alternators.
CDI (Rapair) is the leader when it comes to outboard ignition parts (stators, triggers/timer bases, power packs/switch boxes, coils, etc...). CDI ignition parts are available for Chrysler, Force, Johnson, Evinrude, Mercury, Mariner, OMC Seadrive and a few others.
Outboard Recycle (Red Rhino) is hard to beat when it comes to remanufactured powerheads, lower units (gearcases), power trim and tilt units, as well as Mercruiser and OMC sterndrives.
Sierra offers everything from gaskets, water pump kits and starters, to complete lower units. They even offer a replacement for Mercury 99186T style trim motors, so there's no longer a need to replace the whole cartridge assembly.
Wiseco piston kits are the way to go if you're rebuilding your outboard powerhead. Each kit includes a forged piston, wrist pin, circlips and spec sheet. Kits are available for Chrysler, Force, Johnson - Evinrude - OMC, Mercury & Mariner, Mercury Sport Jets, Nissan & Tohatsu, Suzuki and Yamaha outboard motors.
Those are the main brands, but we also offer parts from Aqua-Power, Arco, Barr, Detmar, GLM, MES, Osco, Teleflex, Tempo, U-Flex and many others.
Marine Specialty Tools
In addition to standard hand tools, some jobs require marine specialty tools, like lower unit shimming and reading peak voltage (DVA) when testing ignition parts. If you need a special tool, just email us the part number in the manual and we'll look it up.
Can't find what you need?
We will always have more available than what's listed on the site, so if you can't find the parts you need, just fill out this form and we'll look it up for you. Please include as much info as possible to make sure you receive the correct info. It's also a good idea to include the part number from your old part, if available.
What's this part called?!
If you figured out which part has failed but you're not sure what it's called, just provide the best description you can, along with the part number that's on the part. That's generally enough to match it up for you.
Some manufacturers have different names for the same part. What Mercury calls a switch box, OMC will call a power pack, pulse pack, or amplifier--depending on model/year. Others might call it a CD module, ignition module, ignition box, etc...
What OMC calls a timer base, Mercury calls a trigger. You may also hear them referred to as sensors or sensor rings.
Gearcase and lower unit are the common terms for what some people call a foot... and the list goes on.
Ordering Tips
Whether you're ordering parts, or just checking price, it's important to include as much info as possible.
Please be sure to include your engine serial number if you're working on a Mercury, Mariner, or Mercruiser.
If you have one of the following, be sure to include your engine model number: Chrysler, Force, Johnson, Evinrude, OMC Seadrive, OMC sterndrives, Suzuki and Yamaha. If you're working on a newer Force, you should also include the engine serial number as well.
Once you have all of the information you need, you can submit your order through the secure order form.
