It was finally time to bite the bullet and bore the 4 inch holes in the hull sides for the exhaust side pipes. This was pretty scary stuff, as we measured the position and angle of the each hole many, many times. Then, with a 4 inch hole saw on our trusty Dewald drill, we took a deep breath and bored the two holes. The use of side pipes make for a very simple and clean installation, eliminating the need to run the 4 inch pipes all the way through the transom, and causing interference with the aft cockpit flooring. To keep the exhaust noise within legal limits, we run 2 slip-in marine muffles inside each exhaust pipe. They are held in place by set screws, which allow the mufflers to be easily removed when the boat is run on the APBA Vintage Race Boat Circuit. Work also continued on the transom cavitation plate assembly.

Compulsion will debut this summer at Clayton, NY:

Next, the Chevy 383 stroker motor was pulled and hauled back to Larry's Auto Machine in Stonington, Connecticut to complete the detailing and to break the motor in on their dynamometer. These guys are good, and when the motor was run on the dyno, the motor was tuned for ultimate performance, the horsepower and torque were measured as adjustments were made, and a complete printout was produced for documentation. We were expecting 450 HP and we were not disappointed!

Bill & Denny,
The boat looks terrific on land but that's not
the purpose. GET IT WET and post some pictures

Will do Rob,

We will be hauling “Compulsion” in our Wolfeboro 4th of July
parade and then we will all gather for the launching ceremonies.

Can’t wait to see if the boat actually floats, and to make some
noise with that 383 stroker motor. Was on the dyno yesterday
and we got 500 hp at 5,400 rpm’s – perfect ???!!!
