An added bonus to removing the A4 from the boat was the chance to take the cockpit drains apart and see what was up in there. I don't know if it is true of all Bristol 27's but what I found was unacceptable and dangerous. The cockpit 1 1/2" OD male end (molded FRP) was connected to a 1" ball valve via a 1 1/2" hose, a plain steel close nipple and a plain steel connector. (This resulted in a 1 1/2" OD to fit the hose). As an added attraction the ball valve was frozen. Open.
No need to mess with hose clamps - just shook the hose and the nipple sheared at the valve.
Please don't tell me the factory did this.
Below is my solution. The 1 1/2" ID hose slides over the1 1/4" OD hose perfectly. McMaster-Carr 1" NPT to 1 1/4" barb. Don't waste your time looking for a 1" NPT to 1 1/2" barb. And the hose is cheaper.
