#1 in Over 75 kgfFull review
For a 43 to 62 ft boat with a big battery bank. Most boats this size are better served by a 24 V version if the maker offers one.

3.2/5
For a large boat on 12 V that needs more than 75 kgf. At this price compare the Sleipner SE80 and its 24 V version.

Sleipner SE80 Tunnel Thruster 24V
#2 in Over 75 kgfFull review
The better SE80 when your boat has 24 V batteries: thinner cables and a lower price for the same thrust.

Sleipner SE80 Tunnel Thruster 12V
#3 in Over 75 kgfFull 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.
