Hi all! I am carrying out a major engine overhaul on my Ri217. The cylinder block is bored to the second repair size 020 (0.5mm). Enginetech P5038(8)020 pistons will be installed. The manufacturer recommends setting a thermal gap of 0.03 mm, but this is for land use. Is there a difference in thermal clearance between marine and automotive engines? If so, what should the clearance be on my ZR409? -
Water in Cylinders
byerman posted a topic in Centurion Boat Maintenance, Performance, Troubleshooting
Hey Crew, 2014 SV233. There is water in my Starboard (driver's side) cylinders. None in the port. Clean lake water. About 1/2 cup total. No coolant. Oil is clear. No water in oil. Oil level is not rising. No water in Port side. There were no issues prior to the winter. I had the boat "winterized" and "de-winterized." When I let the cylinders dry, the boat runs well until I stop. When I stop, I don't turn off the engine (to assure there is exhaust and no opportunity for water to back-flow). I did have one issue last year with overheating. My boat did not come with a freshwater strainer. Debris from the lake destroyed my impeller and the boat overheated. After the impeller was repaired, the boat worked well the rest of the summer. I am getting codes 1325 and 1326 FMI 31. My dealer lost their license and the dealership when to another local dealer. Both shops are great but I am the only one that "owns" the problem. Any ideas? Blake
