May have screwed up. Took the boat out while it was a bit choppy and the water pump belt decided to jump off overheating the engine. Fast forward I test for spark and fuel good to go there. I test all the cylinders and all good except I am getting no compression (0) on 3 and barely any (~30) the opposite side 4. Thinking I blew a ring or something in those two. So wondering how much work is ahead of me before I start googling repairs or is it worth it just to take it in? Any insight or help is greatly appreciated!
