I believe that one of my trim cylinders is leaking on my Yami 250 TXRY (204 hours on each). I was tilting up my engine after a trip this weekend and noticed that the pump was making a gurgling sound and was tilting the engine very slowly until the trim piston rods were at their maximum stroke...

On most of my trips, I am travelling in 2 to 3 foot seas on the nose and sometimes they can end up being 6 feet high by the end of the journey. How would you guys trim the tabs and the engine tilt on a Marlin in these types of conditions to avoid taking a real pounding and what rpm would you be...

I was replacing the thermostats in my year '2000 250 SX TXRY that has 190 hours of running time in salt water. Inside the thermostat housing was a large amount of salt scale and calcium buildup. My questions are: 1) Is it advisable to scrape this out or will small particles plug up the passage...

I recently re & re'd my water pump impellers last fall and ran the machines twice without any problems. I then experienced overheat problems after the first start up of the 2009 season. Some of the local mechanics at my marina have suggested that maybe the impellers were inserted into the...

I had my mechanic come down and do a dockside test with with his Thermometer to check out my low idle overheat issue on both engines. Of couse when he was ther it did not happen. His theory is that since we had a very cold winter, the wax in the T Stats might have hardened and it might have...

I posted back in July about an overheating problem on my port machine. I have replaced the Thermostats, Water Pump Impeller, Cleaned the PR Valve and tested the Thermosenders and I my alarm still trips from time to time at various rpms. Any ideas??

Hey guys; I was leaving for vacation this morning and my port engine overheat alarm went off after about 10 minutes at 3,800 rpm. I shut down the machine and went back to my berth on one engine. It looks like the waterpump is operating since the stream of outflow was the same on both...
