  5. Sleipner SE80 Tunnel Thruster 12V
    #3 over 75 kgf3.7Full review

    Strong thrust for a 33 to 49 ft boat that has only a 12 V system. If you can run 24 V, the 24 V version needs about half the current.

    #2 under 45 kgf3.5Full review

    The cheapest way into a Sleipner tunnel thruster, for a small cruiser or runabout. Pick the SE40 if your boat is near the top of its length range.

  8. Sleipner SX35 External Stern Thruster 12V Discontinued
    #8 under 45 kgf2.8Full review

    Only worth it when a tunnel can not be cut, such as a shallow or cored hull. For every other boat a tunnel thruster is far cheaper per kgf.
