My V-20 performance

[THEFERMANATOR]

I have the same boat with a 1.6L SEADRIVE and it had a fresh rebuild on it. I was using a 15 pitch stainless prop and was turning 5300-5400 WOT with me and 2 dogs in the boat and 3/4 tank of fuel. The 1.6L is pretty underpowered for a V-20, and milage will suffer because of it. I had to run 4200 just to keep the boat on a plane with mine, and it sucked down 35 gallons in 2 1/2 hours of running during break-in(just before the transom delaminated). The 2.0L has ALOT more power potential to be had, but a repower with a bracket would make the most sense financially if you keep it.

Something is really wrong with the fuel consumption you've quoted. I've had 8000 pound boats that used less fuel. My 248 Offshore with twin 140's would run a 30 miles on 32 gallons with smooth seas.

1.6 litre parts are cheap, if you can get the HP up maybe you can re-prop to cruise below 4000. As long as you're cruising at 4500 you can forget about mileage with that crossflow motor.

You HAD a 248 OFFSHORE!?...lordy, what happened to it

I bought a 248 Offshore new in 1985 and powered it with twin 1986 Evinrude looper 140's. I ran it until 1994 and have since owned a few more including a Grady White 248 Offshore with twin 130 loopers. The Wellcraft 248 was the best boat I've owned, I had it 140 miles offshore once and typicall ran 80 to 100 mile out. It was so easy on fuel compared to the Grady White, it planed out nicely at 3500 and cruised economically up to 4300 which was getting close to 35 mph. I never installed trim tabs on the boat because it planed so flat at such a low speed. It had the best walkaround design I've seen since the front deck walkway turned outboard and drained over the side.It would really scream loaded lightly and it's embarrased a few bass boats and ski boats. I sold it to a car salesman that forgot to install the plug....he thinks. They're lucky to have survived. It went down in WC Block 110 about 18 miles south of Cameron, LA in the winter of 1995. They were picked up by a commercial boat minutes later. I saw a 248 project hull for sale at a marine salvage place somewhere around Atlanta. They also have a 21 Nova for $750! I always loved the look of the Nova. I belive the place might be called Lanier Marine Liquidators.
