Water in bildge only at higher RPMs

[Devid]

Hello,<br /><br />I have noticed that at the beginning of the day when I check my engine fluids the bildge has no water and everything seems good. If I just idle around for the day there doesn't seem to be any water added to the bildge. However, if I have run the boat on plane for a while and turn on the bildge pump there is alot of water that comes out.<br /><br />We have a 1988 Welcraft Antigua 265 cabin cruiser with a 7.4L Bravo 1. I have actually looked in the engine compartment while underway and cannot find the source of the water. It's a lot of fun riding beside a wide open 7.4L in cramped conditions and waves to boot. Yee Ha.<br /><br />Anyway any ideas or what I should be looking for.<br />Thanks,<br />Deev.

hello<br /> check all the bellows. shift cable and drive. then check the exhaust ypipe for leaks while running check anyting down stream of the seawater pump. if the engine/drive mechanicals are good start checking thru-hulls. I just repowered a 86 33ft will crack and found 2 cheesy factory plastic fittings that were bad. one was cracked and the one for tyhe sink drain was broken off just inside the hull. everytime he hit a wave it had an 1 1/4 hole under water.<br />I fond a cracked plastic valve on a 2003 whaler today while looking at a fuel problem so its not just wellcraft that uses cheepie stuff. plastic thru-hulls on boats lager than 16 ft should be against the law .<br /> good luck and keep posting.

Thank you Rodbolt.<br /><br />I have just replaced a few of the thru-huls above the water line and didn't know there was anything other than plastic. I will try and find the other type and use them from now on.<br /><br />I will also look again with a focus on the areas you have pointed out.<br /><br />As far as the Will Crack, (had to read that one a couple times to get it) I was going to post another topic on that one. I have been makeing repairs and just keeping up with the cracks.<br /><br />Deev.
