Good to hear you are going to test it this weekend. I'd like to hear your results. We havn't had ours in the water for a year or so, it's been an ongoing project, but the last we had it in the water our fuel pump was going out on us. Saying that, we had somewhere in the 28 knots range around...

Yes I own a 1981 GW Wahoo. I've had a hard time finding many other people that own it. We have repowered ours with a 454 and installed a fuel injection on it. What do you have in yours?

Re: Repower 1988 25 ft. Grady trophy pro twin 180 hp. mercru I have a 1981 Grady White Wahoo 256 with a 454 straight inboard. It has a 1.72:1 Borg Warner gear and 16" prop. I get around 1.5 gallons per hour at around 3800 rpm. Speed in that range with boat averagely loaded in freshwater is...

How's it going on the Wahoo refit. What kind of paint did you use? We had to make a rail repair and we are currently waiting on our carburetor to get rebuilt before we run it again. We had low fuel flow and 2 of the 4 barrels in the carburetor weren't getting any gas, but in freshwater we...

Have you ever been on one of these boat jumpnjack? It seems the ride would be completely different provided the weight being low in the boat versus on the back and high like an outboard.

We havn't run our Wahoo yet. She has a 454 with Velvet Drive and a gear ratio, but I can't tell what the ratio is b/c all the tags are gone. We also have large trim tabs installed which i guess are factory. Anyone have any ideas about performance with this boat. We are still about a month...

Yeah I am glad to see someone else who owns a 1981 Grady-White Wahoo 256. We are currently upgrading her with a new rail, winshield, and some mechanical work. New coolers, etc. We have a Mercruiser 454 installed and have hopes of a top speed around 40+, but we will see in about a month or so...
