Gas or Diesel 3100 Open

[ReelMagic]

I owned a 1997 31 Open w/454 FI Crusaders for over 10 years in salt water. Engines were fresh water cooled and never had a problem with them. As previously stated you want engines fresh water cooled. Don't think Tiara offered engines WITHOUT fresh water cooling... We traveled extensively all over the east coast each summer from our home port on the north shore of Long Island as far south as the Chesapeake, north to Montreal CA, and east to Boston and points north of Boston. Nantucket, Martha's Vineyard and Block Island were other places traveled to... Engines never let us down and speed/fuel consumption weren't bad... Cruised @ 23+ knots with a fuel burn of 30-32 GPH at 3200-3400...Prefect boat/engine setup.. Believe majority of 31's were powered by 454 Crusaders... M2C
