Found out, after learning a lot more about my engine exhaust, that the problem was actually this build up in the raw water pump hose. Fixed that, engine seems really happy again. Replaced the impeller, bent back most of my bent bow rail with tie-downs, might try a halyard next. Installed a light, tied up loose wiring, cleaned, added a strap to keep the table leg up and free up more storage space, went sailing on my neighbors for-sale hunter 15 to bluff cove and back. That was the most fun of the weekend. My other neighbor Connor and I took turns sailing the boat on its limit and being towed behind by a rope in the warm water.
