Video link attached to the bubbling/steam coming out of top of motor beside manifold. Seams to be a failure in the exhaust manifold gasket. Cooling lines seemed clogged initially, when running off hose no water came out the exhaust but it never overheated. I then throttled up to try and pop out whatever could have been “clogging it” and then seconds later water began coming out the exhaust along with a large puff/cloud of white smoke. The smoke cleared shortly after. Cooling lines seemed fine then. Have noticed some black particles discharging from the water drain/winterize hoses when I drain after use. While on the water I noticed this coming out of the top of the manifold gasket. Engine was brand new installed from a crate motor in June of 2017. This could have first occurred today, or been occurring for a while but I didn’t own the boat till two months ago. It’s only been run in fresh water to my knowledge, and it’s all I’ve run it in. I’m not a mechanic, and this is my first boat but a big DIY guy. I’ve read enough to know a bad manifold can leak water and cause serious damage. https://www.youtube.com/watch?v=XvcPYz4txa8 |
