Outboard Motor manufacturers, If you are considering buying a new or used outboard engine or outboard boat, this is the page for you! We maintain the most extensive list of Outboard Motor Manufacturer Links available on the net, along with links to parts manual, service manuals, operators manuals and related information. Outboard Motor Manufacturers Directory is a Polson Enterprises web site.
If you happen to be interested in stern drives, inboards, water jets, surface drives, sail drives or other marine propulsion systems, you can find links to their manufacturers on our Marine Drive Manufacturers page.
Calculate your boat speed or prop slip from
engine RPM, prop pitch and gear ratio.
If you are aware of an outboard with a web site not listed, please email us the URL. Also, please contact us with any comments you may have about the site or if you are interested in advertising on this page.
We have lost track of a few marine propulsion companies, for them we provide the last URL we saw them at and the date we removed them from the list. You can find info on several of them in the historical files at the Internet Archive.
Dozens of companies rebuild outboard motors, sell cores and powerheads. Due to high shipping costs, several excellent rebuilders serve regional markets, especially regions with high concentrations of outboards. A few of the larger rebuilders are listed below.

J.D. Powers annually issues awards to outboard manufacturers based on
customer satisfaction in its surveys. Coverage of recent awards is in their press releases.
2008 awards
With Brunswick's recent outboard dumping claims against Yamaha, more people are becoming aware many outboards are not produced (or certainly not entirely produced) by the company selling them.
Trailer Boats recently published an excellent article titled, "Who Makes What for Whom" by Jim Barron in their February 2006 issue (page 28). It details the "who makes what for whom" now and in recent years.
Their article is summarized in the table below.
Drive Manufacturer
Who Actually Builds the Drives
Bombardier/OMC
Johnson and Evinrude
Under both builders, from the powerhead down, the major differences in Johnson and Evinrude are the cowls and paint color.
Until 2006, Suzuki manufactured the Johnson four strokes up to 225 HP.
For 2006 Suzuki only makes the Johnson four strokes up through 30 HP, Evinrude produces direct injected two strokes (E-Tec) 40 HP and above.
Nissan
Nissan outboards are built by Tohatsu
Honda
Long ago, some Honda three cylinder powerheads were mounted on Mercury drive legs and props. For the last several years, Honda has built its full line of outboards.
Mercury Marine
2006 model Mercury four strokes from 2.5 through 30 HP are built by Tohatsu.
Before Yamaha entered the U.S. market, Mercury's Mariner line was built by Yamaha.
Last year (2005), Mercury four stroke powerheads from 25 through 225 HP (except the Verados) were built by Yamaha. Several of those models used Mercury drive legs, electronics and EFI systems (replacing carbs Yamaha used in similar sized engines).
In 2006 models, Mercury four stroke powerheads from 40 to 225 HP (except the Verados) are built by Yamaha.
Mercury's agreement with Yamaha ended in March 2006, at which time Mercury is expected to phase in more four cylinders (75 to 115 HP) based on the Verado engine block, but without supercharging or intercooling.
Outboard Motor Parts Manuals, Outboard Service Manuals, Outboard Operators Manuals
Several manufacturers put their parts manuals online. The table below provides links to online manuals and sources for others. You may need the year, model number and serial number of the outboard to select the proper manual.
Outboard parts are for sale by the engine manufacturers, thousands of dealers and retail outlets. We list a few sources below with web sites that seem a bit friendlier than the others below.
