Forgive me...my first boat.<br /><br />I have my SELOC manual and was looking over the power head, giving it an eyball, trying to become familiar with it.<br /><br />What are the covers on the port/starboard sides of the power head called? I ask because I put a wrench on them and they seemed loose, so i snugged them up a bit. One on port side at the very rear bottom leaked a drop of water every 5-10 seconds when i first crank it. Once it idles a couple of minutes it seems to seal off and quit.<br /><br />Second, Below the cowling, on the drive shaft of the motor i guess, on the rear side there are two square shaped holes. What are they called? I get what appears to be exhaust out of them. At idle, the Stbd one spits just a little bit of water every now and then. If I take my hand and cover the exhaust out the center of the prop, I get a lot more water running out of it. But the port one stays dry. <br /><br />3rd - there is a very small line that runs from a small port at the top of the power head just rear of the flywheel on stbd side, down along stbd side of motor, behind fuel pump, and appears to attach to the power head again at the bottom. I found it was cracked at top where it connects, and cut end off and reattached it. Not sure about the bottom connection as I can barely see it. What signifigance is this small tube, what does it do?<br /><br />Sorry so long, just didnt want several posts.
