Here is something that happened to me last weekend, and I will try to add in as much detail as I can think of in hopes for some input as to how this happened.
My boat was sitting for a couple weeks without using it. Between some bad weather and some previous commitments, we hadn't been out on the water for about 3 weeks.
I had just taken the boat over to top off the tanks (which were 1/2 full) and a pump out. Since it was nearing the end of the season, I added a container of Stabili to the tanks.
I had done my usual engine room check, and did not notice anything out of the ordinary. And 3 days after filling the tanks, we had a beautiful weekend and decided to go out for an end of season cruise.
After we motored out of the marina, we entered the channel and began to bring it up on plane.
The engines maxed out at 2770 RPMs and wouldn't go any further. I tried time and again for about 20 minutes, and then as quickly as it happened, the problem disappeared and we climbed straight up to 3200 RPMs and had a great day with no further problems.
When we we got back about 2 hrs later, I climbed into the engine room and looked around, I found that both my diesel separators were half full of water. I assumed that was the issue why we couldn't get past 2770 RPMs. I emptied the separators and I am hoping for another nice day before I get hauled out, to try the engines one more time.
My my question is this. I have good seals on my filler caps. My marina swears that they have good filters on their tanks to pre
vent water from contaminating their fuel. Some have suggested that with aluminum fuel tanks, and the cooler water and air at night, it could be a condensation issue. However my separators are large and to have them both HALF filled with water seems excessive for condensation.
does anyone have any ideas how this may have occurred. ???????
