Available in several versions the Twinline 520 is the finest inline twin engine on the market. Featuring genuine G260PUM Marine power heads coupled with CNC machined "solid" crank shaft coupler. Each engine is machined and hand fitted and assembled to exacting specification to assure that they will stand up to the power they product.

The Twinline 520 is nearly 52cc's of displacement and can produce between 6 to 10+ horsepower depending on the engine and exhaust configuration.

The inline design makes it the easiest and most trouble-free design when building what we like to call "Exotic" gassers. The engine is designed to fit between industry standard 5" stringer spacing, and mounts with 4 rubber isolator mount pads.

Note: Engine shown with optional exhaust headers / tuned exhaust, available separately.
Note: This engine should be used with a single gas tank and two water pumps.
Note: Our sealed Nose-mount (shown but not included) can be used with this engine along with a square ended drive cable for a totally sealed system with on-board cable greasing. See optional upgrades or give us a call for more information.
