Looking at buying a '63 Nauset with a '94 90 Mercury. With a 19" pitch the boat would just reach 37 on GPS WOT(5500) with two passengers, no gear, 10 gals fuel. This seems slow to me, could the hull be "wet" and weigh more than it should? Motor ran nice, smooth, quiet. Any ideas or is this normal. Boat is F/S with aftermarket glass console and no seating. Newer trailer is asking $4000 firm. Should I just keep looking? Thanks in advance.

Using the Propeller Caluclator ( ) you can assess the performance.

First, I assume the engine has a lower unit gear ratio of 2.3:1. I also assume you have cited the speed in MPH. If these are correct, then the boat is running with about 14% SLIP, which is a bit high. Typically a good prop can run with about 7% slip. This would put your speed at 40 MPH, just 3 MPH faster.

The price sounds quite reasonable, but to me a 1963 hull loses some of its appeal if it is no longer in stock configuration.

Weigh it!

The boat with Nauset console fuel and motor should weigh in at about 1100-1200lbs. Maybe add another 500 for the trailer.

The motor is worth 2500-3000.00, trailer(newer) 750.00 that makes the boat 250-500.00, sounds like a good deal to me.

Took another look at the boat and spoke with the gentleman selling it. Floor is spongy, compresses 1/4" to 1/2" in spots. Told me he drilled it to let it drain ahen he bought it, but not much water came out. Think I'll pass on this one, but thanks for all the help anyway.
