An update on this case, I was traveling for work almost for a month and couldn't work on it. The issue was the starter, just replaced it with a new one and now it starts even easier than before. However, since now I have a new propeller and not the original one that comes with the boat, I wonder if that could make me lose a bit of power. I noticed that the boat now somewhere between 5-10 mph slower but feels more stable. My new propeller is a solas amita 14 - 1/2, 19 pitch 3 blades. I noticed some dirty water in the bilge, and it doesn't seem to be from the lake because of how dirty and smelly it is, maybe some loose hose?
