Exceptional performance, using a stock 1.8L automotive engine.Prospector has plenty of payload. Either build it as an open boat or add windshield, soft top, and a heater, and cruising comfort may be had. With a hull size of 8 feet by 16 feet or the preferred 18 feet, Prospector is a scaleup of the Vanguard design, and uses a Subaru 1.8L EA82 engine. Prospector uses a drive similar to the North to Alaska Explorer.
With a top over water speed of 46 mph with a 1.8L engine and fuel use of around 2.5 gallons per hour at cruise, this sev can run relaxed at 30mph plus speeds on less than half power. This sev can haul over 900lb payloads over big and small waters.
Plans and instruction manual are available for $51US including first class postage (Foreign, add $3). Critical parts for Prospector such as propellers, fans, skirt material, drive hardware and foam for the composite hull construction are available from Sevtec.
Total cost of construction, including engine and critical parts kits for Prospector is $3000 to $7000, and some 600 to 2000 man hours.
