The marine motor the Fisher-Pierce Bearcat 55 was introduced in 1967. Richard Fisher, the founder of Boston Whaler Boats purchased the engine from Homelite Division of Textron, Inc., Originally built by Lou Fageol who adapted a small auto engine into a high-performance marine engine. Homelite marketed the engine from 1962 until 1966 Fisher bought the motor. The motor was perfected and integrated into the sale of Boston Whaler boats.
Some of the improvements include a high-performance gear valve which paired with the existing overhead camshaft and one-piece cylinder block and head made for a durable and trouble-free motor. With it’s new hardened valve seats and Stellite exhaust valves, the need for frequent tune-ups was reduced and the life of the motor was extended between overhauls.
A bypass cooling system was also added to the new Bearcat 55. Now the Bearcat cooling water passed directly to the exhaust system instead of the engine. This left the cylinder block full of water after shut-down, keeping the air out which prevented rust accumulation. and effectively preventing dust accumulation. In addition, internal water jets were added to precisely cool the four-cylinder heads. The improvements were a significant and the Fisher-Pirce Bearcat 55 became a classic marine motor. It is still popular with boat owners looking to restore their 1960’s-1970’s Boston Whalers which feature alone added almost as much to durability as the high-performance valves.
