Here are pics of the hose and glued in thru hull.
One pic shows the OEM tiny 3/4 copper pipe for comparison.
Has worked great. After gluing in, I sanded it flush with the outer hull.
The plastic fitting took the white paint fine.
It has been 4 years since I did this on the last haulout.
At the time, I also reworked my Rule 2000 hose and thru hull. The prior owner simply pushed a bigger hose over the littler hose and left the Rule 2000 to pump through a tiny 3/4 hose. Not good. I went to an electrical supply shop and bought 12 foot of liquid tight non metallic conduit, 1.25 inch diameter, basically a grey flexible PVC hose. Did the same type idea except I used a 1.25 inch white PVC street elbow. And it has worked great. Those pumps can move a lot of water, as long as the head is low. The Rule 2000 calls for a hose size of 1 1/8 inch, but the 1.25 inch hose has worked fine.
