Re: Motor lb range I should be factoring on an 84
Hey Matt,
I've got a 1999 Merc Carbed 200 on my '83 20SF. She'll run around 50 mph WOT with a light load, around 45 with a full load of gear, crew, and fuel, but I'm still experimenting with props. She cruises at about 33 at 4200 rpm. All speeds measured on GPS.
I checked my fuel economy on my first offshore trip and went 82 miles on 30 gallons of fuel. That works out to 2.73 mpg, or about .91 mp$ at today's gas price. The only thing I would change would be to go with a fuel injected motor to improve the fuel economy.
The motor weighs about 400lb. With a full load, I have to keep the plugs in the scuppers to avoid wet feet. Had to gasket the bottom board on the splash well, too. The cockpit drains just fine at the dock with nobody aboard.
Dave
