Bach, any chance I could ask you to post a picture of your exhaust arrangement as it leaves you engine? I've got my 170 Yanmar bolted in, and it looks like the exhaust outlet at the turbo level is scary close to the water-line elevation. do you have a riser to keep sea water from going up the exhaust into the turbo, or just a flapper? Thanks in advance!!!
Actually I do in this thread. https://www.shamrockboatownersclub.com/forums/threads/nearly-sank-my-boat-yesterday.42885/
