The Larson FX 1750 TL O/B 2012 has a documented max rating of 90 hp. Engine specifications for the Larson SEi 180 Fish Series I/O 2005 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.

The Larson FX 1750 TL O/B 2012 is Coast Guard rated for 6 passengers, while the Larson SEi 180 Fish Series I/O 2005 is certified for 6.
