Mercruiser 3.0 problems
 

Hi

My 2004 Mariah SX8 - 18 foot bowrider is taking on a lot of water in the bilge and the engine makes a high pitched squealing noise. The problems are probably unrelated.

Any ideas on what to check and what may be causing these 2 issues?

Thanks
Kerry

Bellows are likely cracked. Its a fairly common issue. Examine your bellows very closely (particularly in the folds) for splits/cracks. If you find one it will need replacing. And its quite possible those two issues are related. Water thru the bellows gets into the bearings causing rust and then squealing.

Any idea on how much a marina would charge to replace them?
